Tropic Marin Bio-Calcium

While I regularly use Seachem Reef Advantage Calcium, Kent Turbo Calcium, or Reef Smart Calcium (a TB Aquatics product), this morning I decided to give Tropic Marin Bio-Calcium a try as I've run out of those brands that I normally use. Despite what the directions say, I am not comfortable just sprinkling any dry powder directly into my tank. So, I mixed one teaspoonful at a time into a 10 oz cup of RO/DI water and added it to my overflow. Before I even reached 1/2 of the recommended dose, I noticed that the water coming out of the return was starting to get cloudy. I stopped my dosing right there, as none of the other brands have ever clouded my tank, even when I dosed above the recommended levels on the label. Shortly afterward and even an hour later, the whole tank was still cloudy.

Is this typical when using Tropic Marin Bio-Calcium?
If so, how long before the tank usually clears up again?

On Saturday, alkalinity was 10 dKH and Ca was 380 ppm. No addition of either (or anything else except a light feeding of pellet food) since Saturday morning until the Tropic Marin Bio-Calcium this morning. Saturday's addition was the last of the Kent Turbo Calcium I had, which was not enough to make up what I would normally add as a full dose. When I added the Bio-Calcium this morning, it was only the Bio-Calcium mixed in RO/DI water.

No, I haven't tested since this morning. I can this evening after work though. I'll check the Mg, too, while I'm at it. I wouldn't imagine Mg to be low, but then again I wouldn't imagine that the Bio-Calcium would cloud the tank either.

I should know better than to mess with one of the tanks in the morning before work... I'm never going to be around long enough to diagnose / fix anything before I have to leave for the day.

Ok, I checked the tank when I got home and it had cleared up. I tested the levels and here's what I get:

Alkalinity: 10 dKH
Calcium: 360 ppm
Magnesium: 1520 ppm

I had been dosing Mg somewhat regularly until a couple of weeks ago, since the Reef Smart Calcium and Kent Turbo Calcium do not contain a Mg component like the Seachem Reef Advantage Calcium does. I hadn't been watching the level very closely, which is why it is a little higher than it normally would be.

I'm trying to get the levels back on track, as I'm about to hook up a calcium reactor to this tank, hoping it will simplify things for me once I get it dialed in.

Yep, it's cleared up. As for the test results, keep in mind that this morning when it clouded up that I had only dosed a little less than half of the recommended dose, so I wouldn't think there would be a noticable change in the numbers since the last tests were on Saturday. Is my thinking incorrect? (presuming there was some consumption since then)

Any thoughts about continuing to use the Bio-Calcium? Is the clouding the formation of an insoluble precipitate, or something less of a concern and just more of an annoyance?
