水草情迷

你地有無每日觀察pH的早晚的變化呀? 我發覺我的魚缸在早上未放Co2時是6.8, 到晚上關Co2後是6.4. Co2的多少是直接影響pH的變化是絕對正常. 但問題是pH每日有0.4上落對魚兒是否有不良影響??

ph 上落, 在這兒有幾詳細說明, http://www.csd.net/~cgadd/aqua/art_plant_co2chart.htm
不過穩定些當然更好, 0.4 的差異, 應該不太嚴重.

I adjust the water flow to have some surface movement, I loss some CO2 this way, but help maintaining a more stable CO2 level at night. pH stays at around 6.4 +- 0.1 all day, and I don't have to worry about surface film.
