Calcium demand question

Bigger never hurts, what is you reactor effluent dkh?

I would bring magnesium up to 1380 to 1400 if I were you, but 1310 is still pretty good.

It's that caps, I have the same problem with my Calcium because of the caps. They just suck the Ca right out of the system.

I lowered my temp and lowered their position in the tank to slow down metabolism. Now I am able to keep my Ca around 380-400, where as before I couldn't keep it above 320-340ppm.

I have the same problem as you Marie. Top off with a Kalk reactor, Calcium reactor going 24/7, and I can't keep up with it. (I have a 150 full of SPS). They just don't make Calcium reactors big enough. If you look at the common commercially available ones the majority are small and IMO greatly over-rated. I am planning on making a new one but haven't been able to find the plastic I need locally yet... mind you I have only made a quasi-effort.

The best media to get is coral sand as I find I can run it to a low 6.2 resctor effluent ph and not have it turn to mush.

Where do you get it? Is it finer then the common Aragonite media you can buy at the store?

I think the pics tell the story, the Ca is all in the tank, just part of the Corals now. Good Growth! Do you use a Kalk stirrer/reactor? Making the Kalk more concentrated may help.
