Hi, I’m trying to understand the water I have in my house and what my best solution is. I had a some Otto catfish which did not survive and then some mollies. I returned the mollies to the store as was concerned about my water and wanted to figure out before went any further. The water in my area is commonly referred to as hard. But my house has a water softener. I have 2 tanks. One I’m trying to cycle and one that has a snail in it. Ammonia, nitrate and nitrite are 0 in both tanks. PH is high in the one I’m trying to cycle (around 8) and KH is 6. But in the other tank the ph is 7.4 and kH is showing as less than 1 (i think). I’ve been testing KH around my house and trying to understand. Can anyone help me understand what I should be measuring, what good levels would be - was hoping to put Cory catfish in the new tank when it’s ready.
