My calcium stays at 420 with just plain PWC`s. I agree that you have to test first and know where you are. Coraline will come but you`ll have to be patient and keep trace elements stocked with weekly PWC`s.

Understood. I think I will return it to the store in that case.

I am hoping to completely overstock my tank with corals, as I think that look is really nice. Also, I don't think it's bad for corals at all as long as I keep them in shape and cut ones that get too large.

The only thing you`ll need to keep an eye out for is to make sure they have their space as to avoid stinging tentacles from LPS corals and chemical warfare between leathers.

...and getting a test kit for Ca to see where you're at in the first place.

I've recently tried to get my Ca levels up. In a nutshell, no matter how many or large of PWCs I would've done, it would've been impossible to raise my levels to 400 as my freshly made water was coming in around 360. Before I put a single thing in my tank, I got a test kit to determine what the Ca levels were in my tank, as well as in my freshly made salt water. Only then did I do anything to alter the levels.

Now, I've got my tank between 410 and 420 with alkalinity at 9 dkH (which is something else you're going to have to test for if you start altering your Ca levels) and know exactly how much Ca I need to add to my PWC water to keep it at that level, as well as how much 2-part Ca additive to add each day to keep my coraline algae growing strong. But the key to all of it is knowing what your Ca and Alk levels are to start with.

This is the article that made it all "click" for me...

... and here's the link to the "long story" of my battle with Ca levels, just FYI...

That's great Kurt, thanks for the experience! Not all water/salt mixes are equal. I tested my well water for Ca and it was off the charts. If I premix my water for more than 3 days, the Ca will build up in the bucket.

Kurt, others may be interested in the brand salt you're using too. What is it?

I did Oceanic for a long while because it gave good Ca levels, but am currently switching to Instant Ocean to better maintain the Ph.

GoUD, what brand of salt are you using?

Reef Crystals... mixed up to 1.024 gives me about 360ppm Ca, 8-9 dKh, and about 8.3 pH. If I remember correctly, I also get 1180ppm Mg out of the bucket.

I mix up my salt in 3.5 gallon batches (using 2 cups RC mix) and have made a premixed solution of TurboCalcium and DI water. I add 4 ounces of this solution to my 3.5 gallons of SW and that elevates the Ca levels of my freshly made water up to about 420ppm. I can't remember the amount of TurboCalcium I used for the 32 ounces of mix I made up, but when I get back home tonight I'll look it up and post it.

[Edit: OK... looked it up and I used 4 tsp (teaspoons) of TurboCalcium in 32 oz of DI water. When I add 4 oz of this solution to 3.5 gallons of 360ppm Ca water, I end up with around 425ppm Ca water.

Hey guys im curious as to what mix melosu58 uses to keep calcium steady with PWC alone,and GuOD I would say that in most cases you are not going to want to use your tap water(its hard to say what might be in there)
