I have a 90gal/30sump system with polyps, leathers, shrooms and xenia. I know my corals are not calcium hogs but I do realize they need some amount so I decided to run some tests. My akalinity was 6dkh and the calcium was over 400. I can't tell between purple, lavender and periwinkle so I can't give you guys an exact number but I do know it's higher than 400. My pH swings between 8.1 and 8.25(pinpoint monitor)
Now to the point. I dosed w/ the 2part ESV system and got the akalinity up to 8dkh and the calcium is still above 400. The instructions recommend to dose 30ml for each part/daily. Knowing that every tank is different and has different needs I don't feel comfortable dosing 30ml/day. I stopped dosing and plan to test daily to see what happens? Any input?

When it comes to adding anything to the tank , Test. and I have notice that when reading the label they can be on the high end of the scale. If I add something I start out adding less and then work up to what is needed. I am only saying this as I really don't add anything to my tanks. I do drip kalk and have a calcium reactor on my reef. and I do alot of water changes with reef cystals where I get pretty much waht I need to have a healty tank.

So like you said take reading and see what You have before You start back up and then you can adjust it to your tank

I think you are doing the right thing. Don't go by the instructions on the bottle...go by the results of your own tests. :)

use your test results, then if you wnt to hit the exact mark for the dose, go to one of the calcium and alkalinity calculators on the 'Net.

I agree, I wouldn't add anything to your tank unless you have some corals that require more calcium - - good water changes and decent detritus cleanup should be enough - - I hate using the additives!
