Hello all ive been around here for a few months and i love reading nearly all the post to try to learn all i can. Right now im having problems with my tank. I've had the tank since Oct of 2014. Its a 20 gallon tall stocked with 3 RCS, 3(2) mollies 1 is in QT tank not getting any better. Ever since i bought it i cant keep fish alive for long; at first it was new tank syndrome but after reading up on that i did a fishless cycle in about 28 days with the HOB.
In December i bought a new canister filter and ran the filter with the old HOB one. I use to use tap water for PWC with conditioner/stress coat every time, but now i use only deer park spring water every change. By now i would expect the water to be 100% cycled and safe for the fish.
pH-7.6
high pH-7.4
Ammonia-0.25
Nitrite-0
Nitrate-40
Filter is Marineland C-160
I can change the water and my Nitrates and ammonia don't go down too much, as well as changing water i have moss in the tank so shouldnt that bring my nitrates down too? I do not use any firts because of the RCS, and it can cause swings too.
Could tank temp changes cause things to go crazy, i have the hottest room in the house so this could be a reason too.
