Hey there, I'm just trying to verify that I'm not going crazy, and that my 2-part consumption is "normal" I have a ~380g display tank (600g with sump, etc.) that has been set up for about 6 months, and is very lightly stocked - about 10 torch/hammer frags with about 2-3 heads each, about 10 acro frags of ~1 inch, 10 acans of 2-3 polyps each, and about 10 other small frags of chalice, and other encrusters. So, basically everything is very small. Yet, I'm adding about 300ml of alk and CA a day (sodium hydroxide and calcium chloride), and a gallon of Kalk each day too. I have had to increase ALK/CA dose steadily every week for the last 3 months. I'll be switching over to a CA reactor eventually, but for the time being am using 2-part. I started with dry marco rock, which is now heavily encrusted with coralline, and have until now attributed the high consumption to that explosive coralline growth. Anyone else have a similar sized tank, and what is your 2-part consumption? I do have a little precipitation on heaters and a little clumping of some of the sand, but I'm not sure if that is a significant factor? Everything is dosed into the overflow, at alternative times - so very high flow. Tank is healthy otherwise, pH of about 8.1-8.2, ~8.5 Dkh, 425 CA, 1400 Mag. Acros haven't shown any real growth yet but I wouldn't expect it (only added those frags about 6 weeks ago), but all the LPS have. If this is the rate I'm going and it is normal, I might have to get that CA reactor sooner rather than later. Thanks for the help!
