I just read an article talking about being careful about which water conditioner you use to treat your tap water. They said it's best to use a simple dechlorinator in planted tanks because if the conditioner binds heavy metals, it can make them unavailable to plants. Anyone found this to be true? I was also wondering whether ammonia,nitrite, and nitrate removal are beneficial features of a planted tank conditioner?
I currently use PRIME by Seachem. It's one of those "all-in-one" recipes. It removes Chloramine, Chlorine, and Ammonia. It "detoxifies" Nitrite and Nitrate. It also provides a Slime Coat. Another cheap water conditioner I use is Aquarium Pharmaceuticals "Tap Water Conditioner". I usually just use this to add to small quantities of water like what I fill my canister or buckets with, since it only takes one drop per gallon. This one Removes Chlorine, breaks the Chloramine Bond, and Detoxifies Heavy Metals. Should I be looking for another conditioner? I have not noticed any problems in my planted tanks (or even my FO tanks), but I was wondering if maybe I'm wasting fertilizers compensating for these losses? I understand how it's easier for plants to utilize ammonia rather than nitrate. Am I really losing anything beneficial?
