RIP Steve Irwin
Alright so after testing my tank for the first time in a long time a couple weeks ago and finding the KH terribly low and finding my Ca through the roof I ordered a Magnesium test kit and found it at maybe 1200 or so. So I added some of that and got it up to 1400 and I also over time buffed my KH/Alk back up but did it slowly so I did not stress everything (over a period of almost 2 weeks I brought it back from 4.5 to 8.0) I now noticed that my Ca level is at 500 compared to it testing higher than that the time previous to all of this. Anyways my thing I am getting at with all of this is today I tested my KH then topped off my tank (for a couple hours as I have no auto top off.) I just add 5-10 gallons every 3 days or so directly from my RO. After topping my tank off my KH went from 8-7.5 and when i tested the source water it was at like 10 or so???? So if it was higher going in why would it result in a drop in the long run? I hope this makes sense....maybe I need to test the source water over again but I am sure this is what it was when i tested before. I won a kalk reactor a while back and have been meaning to hook it up but I want to hook it up directly to my r/o with a float switch or whatever. Does anyone have theirs set up like this? What auto top off do you run?
