Tap Water: High Ammonia & PH
I live in the Sarasota, FL area and I'm very concerned about our tap water. Out of the tap is has 2.0ppm ammonia, and a PH of 7.6 (maybe even a little higher), a GH of 14, and a KH of 3.
I'm just cycling a 65G now and will be setting up my 30G when the first is done. But it took a lot of work to get the ammonia down so I'm worried about how I'm going to do water changes. The first treatment with Amquel only brought the ammonia down to 1.0. So I treated it again on the 2nd day, but it still took until about day 4 to drop to 0.
I've already got 6 zebra danios in there to start the cycle and I used eco-complete and some Turbostart to try to jumpstart the cycle.
My question is: should I get an RO unit and mix half with the tap water when I'm doing water changes? I'll still treat with Amquel, but that should bring the ammonia down to what Amquel can manage. The bottle says it can treat up to 1.2ppm ammonia.
From what I'm learning about water chemistry, since the KH is low, doesn't that make my water more susceptible to ph swings? I'm hoping once I start the CO2 injection it will lower the ph just a bit, but I'm only wanting it to get stable around 6.0.
I would love to talk to someone who already has planted tanks in the area. . . someone with experience with the water. Or anyone out there who has some experience with this.
I am wiling to buy an RO unit but not quite ready to have to get a plumber to install, figure out where to put it, etc. . . LOL
Thanks for any help!
