Balling and why

[Aqua-Digital]

Here is a great thread from Zeovit.com where one user switched from doing a NON NACL balling system to the full system as per hans original recipe

Hi,
My tank runs the balling system together with Zeo. At the very beginning of using the balling I didn't add NaCl free salts. There were 4 solutions: calcium chloride dihydrate, magnesium chloride hexahydrate, magnesium sulphate heptahydrate and sodium hydrogen carbonate. I used to have trouble with keeping water parameters stabile then. After about half a year I introduced some changes; instead of magnesium sulphate heptahydrate I started using NaCl free salts and noticed that parameters became steady. Since then there has been the need to adjust them sporadically.
Do NaCl free salts cause the build-up of the elements? I don't know, I haven't seen any evidence of that so far. My corals are fine, the live rocks are clear, without undesirable algae or any other nasty stuff. Everything is ok. Maybe in case of an excessive additional supplementing along with the balling method with NaCl free salts, there's a major increase in some elements and perhaps that's a problem.
I'm neither a scientist nor a chemist, so I can't say for sure whether NaCl free salts with Zeo are a good or bad thing. As most of you, I try something and then observe the effects. For me it has worked, at least so far.
More than 3 years have passed since I started the balling method and about 2 years of Zeo method.
These pictures aren't made up by Photoshop or another programme - they show real colours in my tank. The pics were taken yesterday. There have been 8 months after publishing my tank as DTOTQ of the second quarter of 2009.
