high calcium
hi thanks for your reply
when they tested the r/o water they put in 2 drops and the color changed same with the tap water, when my tank water was tested it took 7to 8 drops for the water tochange color the test was for calcium. but they didnt check any others besides the ph the ph was 8.2 hope that helps? |

um, pretty sure you couldn't get 800 ppm Ca, it would precipitate out well below that.
What kind of test kit? Are you testing CaCO3 hardness (carbonate) or total hardness (Ca + Mg)? Oh, and welcome to the board!

Re: thanks for your reply
Hagen has SW test kits. I use a Hagen calcium kit. 8 drops from the third bottle of the test kit would be very low calcium. Multiply 8 drops by 20 to get ppm with the Hagen kit, which would be 160 ppm calcium in your case. Don't know why your lfs says your calcium is at 800
 By all means, get some test kits so you can measure readings at home. From what you say about the lfs, I don't have much faith in them  |
