Community Fish tank water Levels?

All look fine to me but the kh should be around 4-8 and the gh? you sure you got the right reading? I would expect it too be 6-14 I might be mistaken for something else. I would lower the temp just a tad bit to 78 or 76. pH is fine though I leave mine at 6.7-8. Yes I've kept live plant before and know how it work but still if you claim to have an stock planted tank you must be pumping co2 and that can bump of oxygen out of the water. I usually keep my tank at 24 to 20 gallon. It was at 30 to 20g but they look too cramp. Didn't look nice to me, Keep it bottom feeders, mid, and top if you want to stock it crazily. Another than that your tanks seem good.
