Just a curiousity question...what kind of calcium suppliment do you use with your tank? I've been using Kent Marine liquid calcium, though the current bottle will be gone in another couple of weeks and I may try something new.

Tumbleweed

That is the same one that I use, and I like it. Never even really thought about changing.

What's your calcium at ? What brand of salt mix are you currently using ?

sgould

I use Instant Ocean salt mix. Calcium hangs in the 390-400 range.

Try switching to a Pro type salt mix. This will increase your calcium and magnesium.
Examples:
Instant Ocean Reef Crystals, Red Sea Coral Pro and OceanPure.

Tankerini

Whats the ideal calcium range?

agsansoo

Somewhere close to natural sea water 420 ppm.

Instant Ocean and Two little Fishes two part.
