Low PH and KH
Hi, this is my first planted tank. It's a 7 gallon cube. My KH has dropped to 1 GH is 166 according to API test. I did a 25% water change and have the same result. Out of the tap the PH is 7 and the GH and KH max out the API test, it never changes color with and I didn't want to waste solution. I don't have a liquid PH test yet, but the seachem PH alert reads the lowest (5.3 i think) and the API test strip reads the lowest (6.0 I think). I have a drop checker and the solution started out blue but now it stays green. I'll try to provide as much additional info as I can.
Substrate: Fluval Stratum
Lighting: Fluval Nano 7 hours of light
Ferts: Seachem plant dosing schedule
CO2: Fluval 45g. I set this at the same time every day an hour before light and off an hour before dark. 1 bubble per 2 second. I work from home and monitor throughout the day.
Decor: small piece of driftwood and Indian almond leaf
The plants are doing really well. Crypts melted but suddenly had new growth. Getting some pearling as well.
I don't want to start adding stuff to target a specific PH necessarily, but I do have a betta who is still doing well, building bubble nests and patrolling the territory. I don't want to hurt my betta but I'm not sure what to do. I have some seachem acid and alkaline buffer on the way just in case.
I'm not sure what to do. Any help is greatly appreciated!
