Hey, yesterday I posted my insane numbers in my tank and I honestly didnt think they were that drastically different than what you would get from the tap, nonetheless today my ammonia was at 1 where yesterday it was .5 and my Nitrites had also doubled through the night. I am also missing a fish I assume it got weak and then eaten, or she is freaked by the water change and is hiding really well. So I did a 50% change and my from the tap numbers are: ph 6.8 nitrites 0 ammonia 0 kh 30 drops x 10 = kh of 300 x 0.056= 16.8 dh GH 1 drop x 20 = gh of 20 x 0.056= 1.12 dh I will copy my numbers from yesterday so you can see the difference ph 6 (or lower) 1.0 Nitrites .5 ammonia KH was 4 drops times 10, 40 mg/L (PPM) =2.24 dh GH at 580 mg/L or (PPM) = 32.48 dh So seeing the major differences especially in hardness I am wondering what is going on in my tank! I have Endlers that are always a different population, 8 (now 7) serpae tetra, 4 albino corydoras, 1 medium sized common pleco and snails. My filter is a double HOB, I am moderatley planted and have three medium pieces of driftwood. I don't overfeed and a large portion of the diet is fresh veggies and fruit that is removed when they stop munching. Thanks for your help. I am wondering if the veggies are making my numbers look worse than they are?
