I mixed a bucket and tested it the other day. Calcium was at 483, Alk 6.9 PH 8.4. I used RO/Di water but no buffer that was recommended when using salinity with Ro water.
I am going to mix up another fresh bucket today after rolling it around a bit and see what readings I get.
Since I have started the bucket, my coral growth has been noticeable in just a few water changes.
I don't like the parameter swings though. not sure if it is because I am not using a buffer to help stablize it with the Ro water or what. A day or so after a water change my Calc readings are 400 alk 8.4 ph 7.8
I havent noticed a residue or cloudy water.
