Good day, I have a 18 gallon tank with 4 guppies, 1 platy (I had 5 but the others died, they slowly started turning a whitish pink), 1 plec (I know a 18 gallon tank is too small, and I'm buying a bigger tank in January) and a snail and recently I've been struggling with a pH of less than 6.2. all my other levels such as nitrates, ammonia, chlorine, carbonates, and hardness are within accepted levels - I use test strips to test water quality. So I bought an alkaline stabilizer which says it will bring acidic water up to pH 7 or at least increase it. It's been two days since I added stabilizer and now the pH is increasing to accepted levels, but the carbonates are increasing beyond accepted levels. What should I do to bring down the carbonate level please?
