I've had my tank 29 gallon for four months now, everything was going good. Now I seem to be losing guppies, I think I figured out as to why just don't know the best way to fix it. the Ph and hardness levels have always been on the higher side (I think its mainly because of my tap water) but now I'm noticing the nitrites are rising slowly in my tank. Tested it today and it was about .3. It could be do to the fact that I had all of the fry in the tank as well as my guppies but I'm not positive on that. So how do I go about lowering the level? I did a pwc two days ago, is it safe to do another one?
