The Puffer Forum

Up untill this morning my gsp was doing fine. Very active and eating well. just checked up on him and he's slightly puffed up and his skin looks a bit wrinkled. His belly is stilkl all white .I have a zoa that's doing great,a clove polyp that hasnt opened up yet and a star polyp that just opened up today....got these corals last week. Params are ammo 0 nitrite 0 nitrate 10 sg 1.024 and temp is at 79F. The only thing that has changed is that i added another base rock yesterday. Maybe i didnt rinse it good enough cause when i put it in the tank some dust came off the rock, I left it like that cause i figured the filters would pick it up. Skimmerless set up running 2 AC 50 with bio mass, phosguard,hypersorb and poly filter(which is light brown).
What could be wrong?

I would definitely add a skimmer.

Puffer is gone. Didn't make it through the night.

So sorry to hear this... Zoas are one of the most toxic things on Earth.
