When I do half water changes in my 5 gallon tank. I add water conditioner to my pitcher of water before I put it in my tank (where my fish stays while I change) my question here is, is it possible to have too much water conditioner? to a harmful level? im not talking like 50 ml per 5gs or anything. my bottle says 2.5ml per 5 gallons. so if I ended up with say.. 3mls could this be bad for my fish?
my second question is the same, but with beneficial bacteria.. can you have too much bacteria? my logic is that if there's more bacteria than ammonia, wont some bacteria and starve anyway?
