Whats the skinny on water changes?
Ok guys heres my problem. Im still pretty new to planted tanks and am having strange readings on my test strips. Before I got into planted tanks, 30 % weekly was fine for me to keep nitrates low. And that was my regiment until something strange happened. I missed a week on changing the water on my 36 gallon planted tank. So the following week, I tested with a strip to see how bad my water was. It was actually way better than before! My nitrates were were barely reading a trace on the strip. I guess maybe 5-10 ppm. But I also noticed my ph had dropped to 6.8. That was weird because this tank used to be my cichlid tank and still contains a couple of lace rock pieces and has crushed coral substrate. Any help on this phenomenon is appreciated because now im nervous about doing anoher waterchange and really screwing up water parameters. Strip reads as follows:no3 0-10 ppm, no2 0, gh 300, chlorine 0, kh higher than 300, ph 6.8 its a low tech tank 1.2 wpg using NO t8 bulbs, cascade 1000 canister with sponge, eheim cocoapuffs, and biofloss, and am dosing every other week with micrbe-lift special blend and tetra florapride.
