Depending on how hot it is I usually go through about a half a gallon to a gallon of top off per day. I went to water store down the street from my place today and i decided to try their "alkaline water" I asked how they raised the pH of the water and the guy was clueless, kept trying to sell me on the health benefits of it. ??? ::) Curious as to how it would work I got one of my 5 gallon jugs full of the alkaline water (which instead of my usual .25 a gallon was a buck a gallon, wish he would have told me that first.) Brought it home and broke out the test kits, checked all the params, 0 on all the stuff that should be 0, including alk. I measured the pH of the water which was 9, I was running low in my sump anyhow so I mixed up 4L of pH 9 water with 4 scoops of the Seachem reef builder which raises alk without affecting pH. That brought the alk up to 12 dKh and left the pH at 9. I also added in 2L of plain RO water to bring the pH down. That should have in theory given me a pH of 8.3. The next time I put the top off water together like that i'll measure the Ph before and after, hindsight being what it is. We'll see how things go from there..
The good thing is i can see new growth on all of the SPS stuff i have added recently, especially on that branching porites Lanny gave me on last monday.
