Hi, I am getting a 75g low tech planted, with apistos, angels, tetras, cory, otos. My tap water is 282ppm TDS, dGH8, dKH 5, pH 8 (after sitting), 2.5 ppm high chloramines. I read that keeping a stable KH (buffer) is important to help keep pH in control. Can I use just my tap water with alkaline and acid buffers, Prime, Excel, SeaChem matrix in canister? Should I do anything else? Do I need RO? I am used to salt water tanks so this is a learning curve. I was told most fish are captive bred and will adapt with no problem?! Newbie needs help!!!
