I can't keep up levels

[reefermadness]

Test.....wait 24hrs and test again. Go to the reef calculator and find out how much you will need to dose daily. Maybe tweek a bit but this method has always worked well for me.

Just an FYI but many tanks including mine can drop 1dkh or more in 24hrs.

Tested today after work ,24 hrs,
Ca read @ 410 after being topped to 420 yesterday
Alk read @ 8.9 on a hanna after being topped to 9 dkh yesterday I find it odd that Ca is dropping faster even though it's added @ a slightly higher dose, again because of the salts, Ca is now added @ 144 per 24 hrs, & Alk is @ 138ml per 24. will check again tomorrow, but a 10 ppm drop in Ca is 56 ml more & the drop in alk is only equal to like 11. So ummm... like WTF.

how bigs your tank and how much SPS do you have in it? thoes drops are what I would expect is a average to above average sps tank.

Ca reactor is the way to go then you can drop testing down to once a week

I think you are stressing too much on having the "perfect" numbers. I have a 125 gallon mixed reef. I dose 260ml of Ca EVERY DAY and can't get my levels over 400! In fact, I usually get a reading of 350. My Alk is 9, my Mg is 1350 to 1400 (still trying to balance it better), BUT.......I have about 140 SPS,LPS, zoa corals/frags/clams in my tank - everything grows like a weed in my tank and all my corals are happy and healthy. My tank is gorgeous, so I will try to up the dosage a little more, but I'm through stressing over it.

So, use your coral's health as an indicator and the numbers just as a reference/guide. If you have a lot of SPS/Clams, etc. using up calcium, you are going to have to dose more.

Holy crap thats over 100 more coral in your 125 than I have in my 120gal! What do you plan to do in a few months when they all start killing each other?

This is something I wonder about... how is it that some tanks we see are so packed with sps on top of sps on top of sps with very little issue & others start killing right a away, different types of coral yes but not always with the same results. I think I'll likely run into some issue's as well, as I've got 45-50 in an RSM 250 & they're all growing happily. When I have to start fragging it's gonna be like frag-mas in CT for whoever wants them.

Well, they are not ALL SPS. About 40 or 50 are SPS - and all frags at the moment - and the rest are Zoas, LPS, Rics, Favia, Acans, etc. However, I am not placing my SPS frags right next to each other. It will fill in nicely and I will simply sell of the frags as I need to trim them. Also, it's a peninsula, so I am placing corals on both sides of the rocks, which gives them more places to grow.

It's laid out fairly nice ATM. Here's a vid to give you an idea :

Thanks, I know I stress over it to much, like I said I'm sick of trying, everything looks good but I was eager to level it off @ 420 or just a bit higher. guess not. spring is here, time to start kayaking already.
