Good luck!

Phosphate actually binds to calcification areas and that is how it inhibits the growth of organisms that require calcium deposition. If you have had phosphate issues for a while, then your (most likely) rock and coral structures are acting like a sink and storing phosphate that was previously in excess. So now you have a reservoir of phosphate that you need to get rid of. And your tank is pretty mature. The tank is a delicate balance and all components are in equilibrium. You removed a lot of phosphate from the water column. That allows the bound phosphate to be released into the water to maintain the equilibrium. So what's my point. Patience. Keep running the GFO and change the GFO out frequently (maybe daily for the first week if you can swing that) to keep it active. Soon enough phosphate will be removed so that the equilibrium will be established at a low level.

Very nice!

The air looks like it's directed through a side channel so as to not to interact with the jellies.

I think that is just waste. My condy does that after a meal.

Just saw this, and I want it! https://www.jellyfishart.com/Articles.asp?ID=266

This reminds me. The Dobie packaging says "not for aquarium use." I found that to be oddly specific.

I picked up my copy at barnes and noble in alexandria. They had one copy, but call the one by you and have them check their network.

The suggestion to create a pile of rubble (I used some nice shells that I boiled before hand) to encourage pod growth is working for me. Jeff

Of course -- Brilliant! Thanks! J

Thanks for all the replies. I'm all for RO/DI water and I like the idea of a small unit. A faucet adapter may or may not work because my faucet is "fancy" -- the aerator is a bit flush to the rest of the faucet (I guess to make it more sleek-looking) which would make connection and disconnection a pain. I tried unscrewing the aerator with some taped up pliers and it was obnoxious to get a grip. Maybe not as obnoxious are hauling up DI water in buckets, but obnoxious. I may go under the sink and plumb in a Tee and have the whole thing completely hidden. Time to get creative!! Jeff

Hey everyone, So I noticed that DC water has some pretty high nitrate levels (I measure about 40-60 ppm in SE DC). I live in an apt so a ro/di system is not very feasible. I saw the amquel plus product and I thought of using that to treat the tap water for water changes. I am wondering what other people do to counter the high nitrates in this area. Do most people have ro/di systems? Thanks! Jeff
