The cloudiness from adding CaCl2 is caused because the calcium you add reacts with the bicarbonate (KH) in your tank and produces CaCO3. The cloudiness goes away when the CaCO3 settles out or (more likely) redissolves. Redissolving the CaCO3 requires CO2.

I think you have gone *way* overboard on trying to fix a calcium problem that you probably don't have. If you have 10 dGH in your tap water then I think it's highly unlikely that any part of your problem has to do with a calcium deficiency.

I've never kept a tank with that much artificial light, so I won't offer much more. As near as I can tell a watt per gallon measure over 5 on a medium-sized or large tank creates far more problems than it solves.

Were I to write

"As near as I can tell hitting yourself on the head with a mallet causes more problems than it solves."

And someone were to reply

"That's the idea behind this. I'd like to determine just how to hit myself on the head with a mallet correctly."

I would have to worry.

What do you expect to do with 5.5 watts/gallon that you can't do with less?

Error, how much calcium were you dosing to get 1 ppm?

Cs' comment about dissolving 1 ppm of calcium is right and got me thinking about it. I posted a comment to the Fertilator bug forum.
