Thanks Troy. The light is already working well.

Forgot about the "how to see if corals are doing well". Too much algae, anemone's look less than prime, sps color and polyp extension. Top down is usually Alk, bottom up is usually phosphates/too much nutrients.

There's a ton of ways to run a tank "well". Unless you're keeping things like sea fans and sponges that aren't photo synthetic, I think the easiest way to keep things healthy is a very powerful skimmer run "wet". But this is just what I've found easiest for me. Heck, Tyree doesn't use skimmers on his systems.

The reason I don't do many water changes now, is I'm removing 3 gallons or so of super concentrated (compared to plain tank water) nasty water a week, spotty = bad critters. So, it's more stable than doing a big water change all at once while still pulling lots of poo. I just do a small water change to get any detritus out and the minerals are getting replace when I add salt to keep the salinity up.

There's also much better tanks within MAAST that hopefully will be shown in some future TOTM columns.
