Hi All
For my RSR 250, I am currently dosing 72ml/day of Alk. I also dose the same amount for Calcium, to keep everything balanced. I know it's higher than most people and I really don't understand why it is the way it is.
Originally after I got all my coral in, 6 months ago, I stopped dosing completely for a few days, did a water change and checked the Alk, it was at 7.5. I dosed to 8.0 and verified it was where it was supposed to be. I did this for 5 days, test before, dose, check after. Using this method, it said that I needed ~48ml a day. And that's where I set it.
I implemented this on my GHL doser and after a day, the 8.0 dropped to 7.0, even with the dosing. I manually add again, and test to verify. The next day the same thing; it drops to ~7.0. After a week, this trend doesn't seem to change. I still need to manually add more Alkalinity.
- I've checked the GHL program.
- Checked the reservoirs to make sure it's filled
- I've checked for leaks
- I've put a measuring cup under the drip tube and measured the amount dosed per day, and it's dead on
Magnesium is good, between 1300-1350. Calcium is reasonable also, 425.
I'm not sure why I'm using so much alkalinity. I don't have many corals
- duncan
- frogspawn
- daisy coral
- torch
- zoas
- montipora
- lepto
Any ideas?
