ph, gh, & kh different in all three tanks
so here's a little background on my three tanks and my tap water:
tap: 8.0ph, 4gh, 4kh
29g: 8.0ph, 8gh, 4kh (Flourite Black topped w/Flourite Black Sand)
10g: 7.8ph, 7gh, 6kh (Flourite Black)
10g: 7.6ph, 6gh, 7kh (Eco Complete Black)
All tanks have driftwood and are dosed with Flourish, Excel, Pottasium, & Iron.
The 29g is home to 8 Emperor Tetra, 12 Cardinal Tetra, and 2 Nerite Snails. The 10g aquariums are going through a fishless cycle right now.
So... all of that being said. 1) why are the gh and kh (in most cases) higher than the tap water? 2) what could be causing this? 3) are these levels ok, or should i be doing something to adjust them?
The 2 10g aquariums are going to house Betta.
Thanks in advance for any tips or advice you might have. There's so much to learn about aquarium and fish care. I feel like my mind is about to explode. Hehe.
