What would you do? Again with the x@#^*! Dosing

Yes its into high flow, it goes though two sump chambers, then though a pump before hitting the DT. Dosing is done using the first two heads of a four head profilux. So I would guess between 15-30 mins between doses. As I've said before the paras were stable until august & @ that point I was dosing almost 4ml per gallon, which caused precip & the salinity to rise weekly while not maintaining CA levels. I can't figure it out unless the ca & mg tests are both pos. Or the ca supp. Is weak?

Thx tips. Read the above q & a as you are asking q's and appear not to be getting the answers.

On the profilux, are you dosing once a day or a total of that volume throughout the day?

Also, how full is your tank of coral? When my nano was full of SPS, it would drop 20 ppm Ca and 1 dKh Alk a day without dosing - likely your dosing regime just isn't cutting it.

Also, Alk of 7 dkH is fine. I keep my alk at 7 - 8 dkh (Fauna Marin supplements on a Profilux doser). I think I'm at about 256 ml (16 x 16ml) of alk a day, and 272 ml (16 x 17 ml) for Ca a day in a 100g + 30g sump (~115g total). Mg I'm using like crazy, but that's a different story.

My SG stays at 1.026, and I do a single 5g water change every week (or two).

If you're not already, I'd break up your doses to be more frequent and dose more in total. Try to test every day for a week to dial it in. Your Mg looks fine, and your SG isn't much of an issue.

To bring everything up, you may want to dose heavily for 2 weeks, then taper it off to a maintenance level. Slowly trying to raise your Ca will take weeks. Alk you probably want to do slower to avoid Alk burn, but Ca you can move a lot faster to bring it up to the 400 - 440 ppm range.

My Dosing is done @ 23 x 4ml doses for CA & 22 x 4ml Doses of alk currently. When I punched the numbers into the brs calculator after testing today I would need to add almost 17 ounces of BRS Ca recipe 1 to top up the CA. to 390 again That's a retarded amount to be used in 4 days, that would equal a loss of almost 126 ml per day, if I added that to the current amount I would be adding 219 ml per gal per day.Which is 4ml per gal How can that be, as there were small signs of precip when I was dosing that amount previously & not maintaining CA levels? Which would cause the salinity to go up like it was before. The maintenance dose is what I am struggling to find. It has this much coral

Yes I remember your tank and your previous post about salinity rising. Maybe you will have to use another method to keep your levels up? That is an insane amount of sps in a small tank I am not surprised you need to dose that much.

may wanna try kalkwasser in your ATO as well.

I was told that it was insane to try by my friend who helped me get started. But is it really possible that there is a maximum for a small tank that I have surpassed? Has anyone ever heard of this before. I really wanted it to be as jam packed as humanly possible.

Have you tried other calcium products?
Maybe u just got a shitty batch ......

maybe you should be running a calcium reactor in stead of dosing it
