Hah great shot of the little guys! Glad to hear they are happy and healthy in your tank.

I know a cabinet guy who is looking to expand I to aquarium cabinetry. Lmk if you want to talk to him.

I fully agree with the above. Individual, isolated, random pH tests are not useful enough to be of much value. But with a controller, you gain the ability to track and see trends which does become useful. I would say the ability to usefully incorporate pH in monitoring your tank's health is one of the things that makes a controller special. You can always control lights using individual timers and heaters using internal/external temp sensors. You can't do much with pH without a controller. To that end, for anyone looking to buy their first controller I would say- getting a controller without the pH capability is almost like getting a controller without network, timer or temp capabilities. It's one of the fundamentally useful things you gain when you get a controller.

Hmmm, pre-seperated resin almost delivered to my door. Sooo tempting.... Can you shoot me text with how late you'll be in the area?

I'm gonna see how this first attempt goes before I end up multiple buckets of spent DI!

Doh, already driving around making pickups. At HD now for supplies. Let's see how this goes....

Thanks Dave and Rob. I'll stop by today and, along with what I saved up, should give me a large enough batch to make it worth the effort. Alan, good idea on doing a quarterly meeting drop off. Although if I'm regenerating it, I probably won't need more after I have accumulated enough. Let's see how this all goes! Ken, Jack is right, like so many other color changing replacement indicators out there, it often tells you to change before you really need. Getting a TDS meter is the best way to know when the DI really needs to be swapped. However, as soon as it stops reading zero, you really need to swap it. The 1-2 TDS coming out of exhausted DI isn't just stuff from the RO membrane that didn't get absorbed by expended resin. It's actually the WORST of the previously absorbed stuff. The the DI resin releases that when it continues to absorb the less bad stuff coming in.

Anyone got any used DI resin they are interested in getting rid of? I'm going to a separated bed design for my water filter system. Figured I may as well separate it myself and recharge at the same time. Looking to do it this weekend so if you are near me in the Reston/Tysons/Sterling area, I could probably stop by. If you aren't near me but have a lot, I may be up for driving out too. Otherwise we could arrange a pickup next time I'm in your area or I can get it from you at the next meet. Guess I'm just to see how much spend media we have floating around in WAMAS land. I guess if someone wants to try it with me this weekend I may be open to some company as I play chemist.

You mentioned you already have some in QT but if you are looking for more, I still have about 20 from the current batch available.

Just noticed this thread. My trio of lemons are doing very well. Laying eggs all the time. I have a batch of babies that I have released to some people. They are still a little small so they can only go in tanks with fish with small mouths...

I guess my suggestion was overlooked (or ignored...).

2 tanks 1 skimmer cup.

Thanks so much for offering patty. If no one has a 29 available, we may take you up in the offer for wither the first or 3rd tank.

Should be easy to raise them if you want. Siphon them out into a 1/2 filled 10G tank. Feed them baby brine for a week and then frozen rotifers or crushed up flake. If you don't have/want to do baby brine and rotifers, you may be able to get away with very finely crushed flake.

Oops, forgot to mention that it doesn't have to be free. It would be nice but I could throw a few bucks in for it. Just can't afford the time to drive all over the place so something near Tyson's/Reston or so would be ideal.

Hey guys, We need a mixing tank for a school so they can accumulate RO water and mix in some salt. It will go on a 17"x33" shelf so a 29 gallon would fit. We might be able to work with a 20 H if we can't find a 29. Anyone know if a 29 can be drilled on the side? Would be nice if we could install a float valve. Thanks all.

No to hit you while you are down but I suggest upgrading your RO membrane to something much faster in the future. 25GPD is too slow for that much tank. I have a 210 and I use a 150GPD. While I normally keep 25-50 gallons of pre-mixed salt on hand, I also like knowing I can do a 50% water change in 12 hours and then another 50% after I wake up the next day if needed.

Btw, I have one lumenarc you can borrow to test of you want. No 250w options though...

My guess is that with the reflectors that low, you should be able to do LPS and zoas on the bottom fine.

If they have to be low like that, you won't get as much spread so the lumenarc may be ok. Your bigger problem is going to be heat. Maybe the 250w is a better option because of that...

Depending on how high up your reflector is, 30" is a likely a little deep for 250W- especially if you are using the lumenarc. You may also get lots of light spilling out. I have a 24x72x30 and 3 Lumenbright pendants 14" over the water with 400W was perfect. You would get the same thing with 2 reflectors. Once you get your SPS grown out, then maybe you could consider going to a 250 to reduce heat/power. That was my plan but I never got to the point where I wanted my SPS to slow down...

Ask Phil at Reef eScape! They are the ones who service the tank. You can maybe also offer your suggestions.

Agree. Even Austrailia, which is probably one of the most heavily regulated dive juristictions allowed this for the invasive Crown of Thorns Starfish. For the divers in this group that want to do participate in local eradication, would suggest getting an non-barbed paralyzer tip on the spear instead. Once you stab the fish, you can just swipe it against something to pull it off. No risk getting stung but a squirming lionfish...

Yes it was..hah..yes it was....

Most definitely! I should have phrased it differently. I was trying to stress how the feedback to Denver's app will be so directly relevant to making ours better.
