There was just a post on this but the answers don't solve my problem. My tank (75g) won't cycle, 3 weeks in, heavily planted in aquasoil, ammonia never got above 0.5, not many water changes, no ferts, seeded with media from my other established tanks. For the most part I've got rainwater coming out of the tap, KH is maybe 0.25 to 0.5--if I use 20ml water it takes 2 drops to get to color change, immediate if using 5ml. Absolutely zero GH. To make matters worse, I used aquasoil as a substrate before realizing the water at the new house isn't the rock hard stuff I'm used to and so the pH is likely less than 6 (low as the test goes) and KH is zero from that tank and my others, lost the 0.5 degrees from the tap.
For the health of my fish (once the tank is actually cycled and I can put them there) I'm assuming I'm going to have to use something to increase GH every time I change the water? What about KH and getting this thing to actually cycle? What products do RO people use? Is epsum salts enough or?
I am used to the exact opposite of this problem so feel a bit lost. But not exactly stoked that I'm going to have to mess with parameters. Thank you for any input!
