Help!! Question about my KH, GH and plants
Hello everyone....I'm new to The Planted Tank however, I have had a planted tank for almost 1 year now. However, recently I am noticing a bit of a problem. I am finding that my pH is actually dipping quite low into the 5.5-6 range within my tank. I have tested my water from the tap: pH-7.0, GH 2.24, KH 0.56.....the GH and KH in the tank remain the same but the pH is usually in the 5.5-6 range. I am doing a injected CO2 obviously, which usually ranges in the 20-30ppm. I know the problem here is my buffering capacity, as I seem to have none. The question I am having is....would it be viable to add about a 2 lb piece of Texas Holy Rock to the aquarium and continue to use the CO2, with ferts and lights etc, and have a more stable pH......I'm hlooking to stay in the 6.5-7.5 range....let me know what you think, if you have any ideas, or need more info!!
