tnnlynch Posted February 14, 2022 Share Posted February 14, 2022 (edited) My water is rock hard but my PH and KH vary depending on the season from the tap. Ph 6.8-7.2 with KH 60-100. I add the occasional wondershell for my shrimp and snails and have crushed coral in my hob(s). My PH and KH still drop in all of my planted tanks with KH hitting 0 in about 8 days. I use baking soda in my daphnia tank to keep higher ph but am hesitant to do that in my other tanks. My fish seem fine in general but I was looking to increase the interval between water changes to allow me to go on vacation and minimize the potential impact on the fish ignorant friend taking care of the tank. I know @Mmiller2001 mentioned potassium carbonate in another thread. I saw a few dosing guides on the net but have not had a chance to compare them.
