What should i buy to purify my water?

[megs_clark]

Iv been using Aqua Plus tap water condition to remove the chlorine, Is that the same thing? After i do a water change i fill the container up get the salt right, put in my Aqua Plus tap water conditioner, I was also adding cycle but didnt for my last couple water changes, and then i let that airate for 7 days till my next water change. I think i need to do more though, Im going to try to find a TDS so i can check my water but have a feeling ill have to order that in to.

I just realized you said that "safe" stuff is also a de nitrifiyer. Ill try to find that and try switching. Sounds like that does more then the Aqua Pluse tap water conditioner

Thought the lower mainland water was rather good right from the tap (treated for chlorine). The crushed coral might be contributing to your problems as well as the amounts your feeding.
