What is the recommended way to boost Kh in a planted tank with CO2?
I'm a newb with planted tanks and am wondering how transferable techniques that I learned with a low plant tank are to a planted tank with CO2. In my low plant tanks, I just add a palmful of crushed coral in a fine mesh bag to the filter and it keeps the Kh at either 3 or 4.
I'm converted one tank to a planted tank with ADA AS and pressurized CO2 a week ago. I didn't add the crushed coral because I thought the Kh wouldn't drop with the CO2 injection. Tested it last night and it was zero. Ph is 6 (or less as this is the lowest reading on my test.) Plant growth is telling me this is a problem as at first the plants really grew but have since slowed substantially and I'm starting to have some algae on the root.
Thank you in advance for any advice you can give me.
