HowardofNOVA August 16, 2005 August 16, 2005 Chip and I where working on my system the Sunday night, Thanks sir for the help! Working on sump, new Iwaki pump, lighting, etc. Had to back down the MD70RLT pump almost 1/2 way and remove my 1" strainers to equalize the flow. Doing some more modifications tonight. Came home from work last night and tank temperature was at 91.5 degrees and both Percula Clowns, 1 Green Chromis and 1 Peppermint Shrimp was down the drains into the sumps wondering how to get back to the top of the ride. I immediately shut off the MH, did a 4g water change, added 2g of RO/DI and added 4 ice cold soda cans from frig (I cleaned them off afterwards) to the sump. Slowly got the tank down to 88 degrees an hour later. Down to 79.7 this morning and back to normal. PROBLEM: Forgot to turn the fan on for my temperary canopy. MH shot the temperature straight threw the roof. RESULTS: So far, my Sarcophyton, Frogspawn and 1 Capenella are a little worst for wear, SPS, Clams, Anenomes, Candy Canes, Leathers, Zoos, Gorgonians, etc are looking great this morning. Keeping my fingers crossed they will be that way tonight? TIP: Chip had some gutter screen type material that I used instead of the strainers. Worked great, with very little restrictions in flow. OH, BTW, I have 4 - 1" Clear Blue Strainers for sale? Howard
steveoutlaw August 16, 2005 August 16, 2005 Glad to hear everything is looking ok. I was going to use some eggcrate material on the end of my 90's to act as strainers. Ever since I hooked up my supersquirt I've had to use a mag 9 instead of my mag12. Can you see any problems with the eggcrate?
davelin315 August 16, 2005 August 16, 2005 Watch out for bleaching, sps will expel their zooxanthellae when exposed to high temperatures (that's what the fears are over global warming and the reefs!). I don't know if one doing it will trigger the rest, but I'd remove it if you see one turning white. That said, I think that sps corals are also exposed to drastic temperature swings and some even get exposed to *gasp!* excessive temperatures such as your own when they are on top of the reef, albeit more briefly, but high nonetheless. Good Luck!
Gadgets August 16, 2005 August 16, 2005 Hey Howard I will be back in town today. If u need any help just give me a ring.
flowerseller August 16, 2005 August 16, 2005 Howard, Getting the rest of the plumbing we discussed finished will allow you to run the one pump "full throttle" which will reduce back pressure on it. Less back pressure will translate to some less heat by means of less friction. Point one of the existing powerheads towards the water surface which will increase evaporation and aide in temp reduction by means of. If temp is a real issue try filling 2 milk jugs 3/4 with water, freezing them, and then alternating them between the freezer and the sump as needed. If you need milk jugs, our 3 sons can create them for you instantly. Glad your new strainers are working for you and call if needed.
HowardofNOVA August 16, 2005 Author August 16, 2005 Went home to check on the tank, Temperature 84.0, turned off MH for a couple of hours. EVERYTHING in the tank is otherwise doing fine so far! Keeping my fingers crossed. Stopped in at HD and got the remaining PVC pieces, going to start selling them stuff here pretty soon! Howard
HowardofNOVA October 24, 2005 Author October 24, 2005 I've got to head to VEGAS this week! I just can't be this lucky!!! I went hunting Sat morning leaving the house before 6am and FORGOT to turn the fan back on my temp canopy. Came home around 6pm. TEMPERATURE 91.7 DEGREES! :o Alot of stressed corals, immediate poured 1g of RO icewater from frig and added icepacks, drained 7g of water out, added 5g of Saltmix water and a couple of RO/DI water. Got the temperatur down to 88 and waited and prayed! By morning temperature was down to 79. With blurry eyes, looked into the tank for the worst! CAN'T REMEMBER CORALS LOOKING SO GOOD! :D Full polyp extension on everything! Even the anenomes where cranking it! Only time will tell, but I've got to MAKE TIME to get my canopy finished!!! Signed, One lucky SOB! Oh, on a side not, ANYONE wanting DEER MEAT, Give me a call! I have about 50-75# that I can offer if your interested. Got 2 more Sat. :D
Folta October 24, 2005 October 24, 2005 Hey Howard, do you manually turn on your fan each day? If so, why not set it to the same timer as your MH's? That way when the lights are on, the fans are on?
steveoutlaw October 24, 2005 October 24, 2005 Howard, Be careful using screen material over your overflows. If something.......like a piece of Nori......gets over top of one of them you could have a puddle or 2 of water on your floor.....not to mention a pump running dry!
Caribbean Jake October 24, 2005 October 24, 2005 next time this or something similar happens, remember that chaning the temperture on your system should be gradual and not a sudden change or your livestock will be greatly affected. I suggest you get yourself a timer $4 and put that fan on the timer. This will ease lots of problems in the future. Jacob
Caribbean Jake October 24, 2005 October 24, 2005 one more thing.... VEGAS? I am going to Sacramento tomorrow for the rest of the week.
HowardofNOVA October 24, 2005 Author October 24, 2005 My girlfriend was over and I turned the fan off late at night to be a nice guy. Forgot to turn back on in the morning when I left, but it usually on a timer, should have turned off at the timer instead of manual control. Steve, you lost me on this one? "Be careful using screen material over your overflows. If something.......like a piece of Nori......gets over top of one of them you could have a puddle or 2 of water on your floor.....not to mention a pump running dry! " ...??
steveoutlaw October 24, 2005 October 24, 2005 Howard- I believe that most strainers are made to stick out of the water. If you just put screen material over a "90" that is totally submerged it can completely block off the overflow.......resulting in flooding and your sump running dry. I may have mis-understood you but I thought you said that you had to take the strainers off of your overflows and were just going to put screen material over them.
HowardofNOVA October 24, 2005 Author October 24, 2005 OK, I got you, your going back to original post! Actually with 3 - 1" stainers, blockage is rather low percentage. I've had one about a year ago was completely blocked with I had a thermoter come loose and suction cup covered outflow. Water came up about a 1/2" but still room to go with no problems. I believe the reason for my zero lost so far was that my system has been running hot anyways lately, as much as 86-87 degrees help here! I heard of other systems doing the same 90+ degrees and loosing everything. Like a said, one lucky SOB!
Lee Stearns October 24, 2005 October 24, 2005 Man and I get nervous if the tank hits 83 degrees- might run a smaller quieter fan 24-7 over the sump.
HowardofNOVA October 24, 2005 Author October 24, 2005 Just got back from stopping at my house to bring in 30# of Deer Meat for some of the staff. Tank was looking good, temperature was about 83 degrees! Was reading a post somewhere that the AVERAGE temperature in Indonesian Waters was 83 degrees. That's average, would be curious to know the high end? Lee, I run 3 - 9" fans currently, 1 fan running in front of the open canopy, 1 over the 29g sump and 1 over the 20g frag tank. Still a chore to keep consistancy, but the inhabitants are holding their own so far! :63: Howard
Eve October 25, 2005 October 25, 2005 Speaking of temperature in general - with the weather turning colder we need to start paying attention to it in the other direction too. I walked past the controller the other morning at around 7:00 am and there was this strange red light on and it took me a minute to realize that that means the heater should be on. I had removed the heater when I switched sumps (the old heater was rusted) and I hadn't even plugged the new heater back in!!
HowardofNOVA October 25, 2005 Author October 25, 2005 I'm just blown away, everything is still doing great! It has to be that I've been running a bit warmer than usual so this high was not as stressed if I would have been consistantly around 80 degrees! Still praying! :D
steveoutlaw October 25, 2005 October 25, 2005 Ok, here's a question. My tank fluctuates from 79 to 83 degrees every day......yet my corals and fish seem to be doing great. I'm getting some amazing growth out of my purple digi and my torch looks like it did the day I got it......and I've fragged 12 heads off of it. So, on to the question: Does our livestock become accustomed or acclimated to the changing temperatures of our tank?
Guest clownfish4 October 26, 2005 October 26, 2005 It's true they become adjusted but it also effects their health. For example, a cold water fish will only last a few years in a warm system. Therefore putting a fish from say 74 degree water to our 78 to 81 may shave a couple years off their lives.
Caribbean Jake October 26, 2005 October 26, 2005 I'm just blown away, everything is still doing great! It has to be that I've been running a bit warmer than usual so this high was not as stressed if I would have been consistantly around 80 degrees! Still praying! :D 43219[/snapback] tell your grilfriend to stay home and watch the fan the tne temp... and feed her venisen meet.... :D
