  1. I loved using a peristaltic dosing pump for my kalk dosing.  Wish I could go back to it, but there just isn't enough room in my stand for a kalk stirrer.  

     

    How often (if ever) do you pull the kalk stirrer out for a thorough cleaning?

  2. This build is too smart for me. But I'm intrigued by what is happening, and I will be sticking around to pretend to understand!

     

    Hahaha it's ok, I'm just about done being an electronics super nerd, and time to switch to reef super nerd....  What am I going to stock the tank with?!

  3. Oh and a major issue I ran into.... The MeanWell power supply I'm using in the controller apparently is pretty noisy and screws up the powerline adapter I use to get my Apex onto the network....  Right now I'm running my Apex with no network.  I bought a clip on ferrite core filter which I hope will help, otherwise I will have to switch to a wifi bridge.   :hammer:

  4. Almost there, finally ready to add a couple of snails and start getting the tank ready for corals.....  

     

    I may still slap a fan on the lights.  They are ok running ~50%, but higher than that and I should run a fan.  And I need to start thinking more about the semi-automatic water change module.

  5. This could explain the fraudulent paypal account that was setup using my CC that was also used at BRS in November.  Paypal was really good about pro-actively shutting down the other account and refunding the money back to my CC.  I just wish they had done a better job of notifying me... I saw a charge/refund from paypal a few days after it had posted and had to call in to find out what was going on, then call my CC company for a new card.

  6. Been awhile since I've update this....  Cycle is done, rigged up the lights in a temporary fashion a week ago and starting the algae phase.  I need to do a full water change, which I'll probably take care of this weekend.

     

    Most of the work over the last few weeks has been on the controller...  Programming is ~90% done, I just need to program the water change module.  I've painted and drilled holes in a project box that will be the case of the controller and I've started mounting and wiring some of the parts.  I've also finished soldering the main arduino circuit board except for 1 capacitor.

  7. question for bbq...

     

    are you able to get your lens open to 2.8 at 1:1? i have heard that 2.8 is only from ~10' to infinity and not close up. At that point, it jumps down to 5.6 ish or something....would love to get your thoughts. do you have the DI or non-di?

    I have the DI version without VC.  I just tested it and you are right, at 1:1 it's f/5.6, and about 12 feet to get 2.8.  I hadn't noticed that before, but isn't really a big deal for me.  I'll mainly be using this for 1:1 or near 1:1 shooting where the DOF is so shallow I wouldn't want to shoot at less than f/8 anyway.  Having only taken a handful of shots with the lens, I'm quite happy with it so far.

     

    I too would like more info on the lens...can you provide a little more details of the exact lens?  

    Here is the exact lens, although mine was bought used so I didn't feel as bad about the price tag on a lens I won't use a ton

  8. Sweet shots, nice lens!

    Thanks!

     

    The tripod will help a ton, not that you need it though =P Very nice photos!

    Thanks, with the super high ISO i was able to keep things relatively sharp while handholding.  Hoping the tripod will let me shoot with some more DOF without being a shaky mess!

     

    Cool coral with that cleaner shrimp, what is it?

    Darth Maul Porites from piper.  It's kept it's color but really hasn't grown in the last year.

  9. Got a Tamron 90mm macro lens for x-mas and finally decided to give it a quick try, here are a couple of the better shots.  Handheld on a D7000 @ f/8 and 6400 ISO, quick tweaks on an older verion of CameraRAW.

     

    Next time I'll bust out the tripod and shoot at f/11 and also try some top down shots.  Oh and maybe try stocking my tank with some more interesting subjects!  :rollface:

  10. Sorry if I gave the impression that I carefully monitor and chase pH, I'm happy as long as it's somewhere in the ballpark of the right value.... The probe was measuring 8.6+ at the peak when I finally decided it was time to try to calibrate!   :blink:

     

    I know that the probes need to be replaced every year or so, I was just surprised that this one only made it 3 months...  After "calibrating" it last night and reviewing the pH graph it looks like the response time of the probe is shot.  After removing the probe from the 7.00 reference solution and putting it back in the tank, It took over an hour to stabilize.

     

     Also, these probes are not meant to be fully submerged, just the tips of the probe in the water - is yours?  

     

    Interesting, I did not know that.... I think mine is fully submerged, or pretty close to fully submerged.  I'll have to find a better mounting method for my next one!

  11. 3 months ago I bought a BRS lab grade ph probe for my apex.  It calibrated and ran fine for a while, but lately it's been reading really high.  I wasn't too concerned and figured it had drifted and needed to be calibrated.  Tried calibrating today, but after finishing the calibration process I put the probe back in the 7.00 solution and it reads about 7.25.  The probe hadn't been out of water in 3 months, but I also hadn't really cleaned it at all (last week when I finally did clean it there was a bunch of red bubble algae growing on it, mostly on the outside casing).

     

    Should I be cleaning the probe more often or did I just end up with a bad probe?  Now I'm debating splurging and getting a Cole Parmer probe or just getting the cheaper Pinpoint one.  

  12. Well I finally got the controller build started.  Right now it's setup on a breadboard for testing purposes and to have the ATO portion of it running before we leave town for the holidays.  Right now the controller has 100% ATO functionality and the ability to monitor temperature.  I also added a bluetooth connection so I can monitor the current status of the float switches and temperature with my phone or laptop.  Eventually I want to be able to use it to send commands to change settings (set time, light schedule, etc). 

     

    During the initial testing of the controller my stupidity managed to fry 2 Arduino chips.  It's a good thing they only cost around $2 and I bought several spares!

  13. What is the sensitivity of your ATO? Do you know yet?

     

    I ask because I started down the road on a 5.5g project similar to this. I abandoned it because it just took too much DIY time since I wasn't throwing money at it. However, the ATO problem was one I wrestled with because it's hard to control salinity swings in a small water volume; ATO switches work fine for larger systems with smaller return pump compartments, but their sensitivity starts to get iffy as you scale down.

     

    For the 5.5g, I started out thinking I would use an internal overflow box just to house the ATO switch and let a micro-jet/pond pump keep the overflow box circulating back into the display. The idea was to maximize the vertical drop in water level for any given total system evaporation - increasing the sensitivity of the ATO switch to total evap and minimizing salinity changes.

     

    I haven't setup the ATO yet so I don't know the exact sensitivity.  I figure that I should be able to keep the water level within 1/2" at all times.  Based on the size of my return area, that's about a 2.3% swing in water volume.  That should keep the salinity within 1ppt.  I can live with that kind of swing in salinity, hopefully corals can too! ;-)

     

    My fingers are crossed that the 1/2" assumption was conservative, but I'll find out once I get it setup.

  14. Thanks!  Although I wouldn't say experienced (my coral keeping experience is only about 2 years)... I think it's more that I love a good challenge!

     

    Wow.  I'd take you up on the offer of advice but I wouldn't even begin to know how to work on a tank of this size.  It seems to be more of an art than a science.  

     

    You must be a very experienced reefer to have the confidence to attempt such a small tank without all the safety that comes with larger water volume.

     

    Good luck!

  15. what are the floats for in the back of the tank?

    The lower one will be for triggering an ATO. The upper one is an emergency water too high switch in case the main float switch gets stuck.
  16. The Good:

    Cycle is going! 

    Decided on a DIY dimmable LED setup using LDD's

    Most of the parts are here for the controller/LED build

     

    The Bad:

    API Test kit isn't reading the ammonia level right after using ammonium chloride to start the cycle.  Red sea test kit is on order.

     

    The Ugly:

    Standing bare foot on a concrete floor, I put my finger in the water to feel the temp of the water.... ZAP.  New pump is on order.

  17. So I've been itching to build another tank, but there isn't much room around the house for another tank so I'm going to take on the challenge of a pico tank with the goal of keeping SPS in it.  

     

    I used to dose kalk using a small reservoir with a stir bar in it to periodically mix it.  Once I switched to 2 part I no longer needed it for anything, so I decided to re-purpose it as a pico tank.  I painted a divider and glued it in to hide the pump, heater and float switches etc.  

     

    Display portion is 6 5/8 long x 4 15/16 wide x 6 5/8 tall = .93 gallons

    Rear chamber is 1 15/16 wide for about .3 gallons

     

    Filtering will be some filter floss with some ROX carbon in the DIY pump/filter chamber.  I plan on setting up an Arduino to control the lights, heater, and cheap ebay peristaltic pumps for ATO, WCs, and maybe kalk dosing.  Lighting will either be a PAR38 bulb or a DIY LED fixture using Evergrow replacement LEDs I have laying around.  

     

    Shooting for semi automatic water changes every 2 weeks.  Hook up an empty gallon container, and a gallon container of fresh saltwater and the controller will complete it in small increments over 24 hours or so.

     

    Hoping to get it wet tomorrow to get the cycle going!

     

    Would love to hear input on the aquascaping and any other tips you guys may have for a tank this small!

  18. Not happening. That's what I tried. If you can somehow "force it" you would probably damage the wire.

     

    Bummer.  I'll probably end up getting one, and seeing if I can rig something up.  If not I can live with it mounted one the side wall for one side of the tank and I'll use the WP10 on the other side.

  19. i got a few folks in and around fairfax that have placed orders and will be doing an ERC DELIVERY at Fair Oaks Mall on Thursday, 8/21 @ 12:45pm - 1pm. shoot me or richard a PM to coordinate your delivery if you want instead of shipping.

     

    if you're in the fairfax area and looking for some primo specimens of coral or fish, shoot one of us a PM and we'll have it ready on thursday!!

     

    I'll be there to pickup my Evergrow individual LEDs  :cool:

  20. No chance. The placement of that wire is poorly thought out for this scenario.

     

    I had sent an email to Logan at ReefBreeders, and according to him,you can remove the pump from the mount, and reattach it so the wire faces the opposite direction.  Is the wire pretty flexible to make a tight turn?

  21. One of my WP10's just died and I'm thinking of getting a RW4 to replace it.  I want to mount it to the back wall and have it rotated 90 degrees so the flow is parallel with the back wall.  Looking at pictures, this would mean the power cord is sticking out into the tank.  Is the mount reversible so it's sticking toward the back? Or better yet, can you rotate it so it would be sticking up toward the top of the tank?

     

    Thanks!
