Last I checked, it was 2. And with the crap I see in the prefilter, I'll keep using RO

I get a reading of 2 after my membrane and a reading of 0 after my di stage. It's suprising how temperature sensitive your membrane is.

The most important food item seems to be zooplankton and without a sandbed you would have much less of it in your tank. Without a sandbed tho you should be able to feed the hell out of your tank without running into nutrient issues.

Now that just don't ,make sence seeing that corals have little algae that live inside them and convert light energy into food for the coral. the only food that went into my tank for 7 years was fish food and it was a very heavily skimmed, bare bottom tank. so basicly a very low nutrent high light envioirment. I think all these "coral additives" are just a get rich quick scam myself, but hey its your money.

Ok, so Ca is fine, not low, for some reason people think you need over 400 Ca in this hobby which isn't true. once you get over 420 you actualy start slowing down coral growth.

Brad, borrow a Mg test kit off some one and test your damn Mg. also what are you Nitrates/nitrites and phosphates. the later two will stop groth in a heart beat if they have a little to much

Do you have access to another system? Have you tried taking a frag out to a new system and see how it does?

I've given some frags to Tyler W. as well as have frags from others that he also has, so I'll check with him. But I suspect they're doing fine. Frags from Snappy are doing well in other tanks locally, just not mine.

Any stray voltage?

try it by holding the return line with your left hand, stand on your right foot, and stick your tongue in the water.

Or like me, put your head close to the halide reflector and then stick your hand in the water and see if an arc forms between your forehead and the reflector.

And as I cant keep acro,s alive, I have no advice on why they dont grow. They grew fine in my 90g with a pair of 250,s but not with T-5,s. However when I was laid up, the frags I had kept were in my 20g with cheap T-5,s and all though browned out, grew well. I,m assuming because the nutrients levels were increased, from the lack of filtration, {no skimmer}.

I have done things the same and had failure and visa versa. So who the hell knows. Many who have lost their sps, seem to have absolutely no explanation for it. You seem to be doing the exact same as before, but must be some little thing thats not the same, that affects the growth of your corals. Esp. with someone of your experience.
