Beverly I find it interesting and heartening that you are one of the very small skimmerless, and sumpless crowd.
In my case I have a 50 and a 20H tank. These tanks have always been skimmerless, and sumpless. The only difference in my case is that I run Chemipure in smaller Fluvals. I am assuming it does a good job, as I don't bother measuring things, and I do very few water changes. Between the two tanks there are seven smallish fish and a couple of Cleaner shrimp. I also have some soft and LPS corals, and zoanthids that grow like mad.
The 20H also has some M. digitata, a bit of Hynnophora, and a piece of staghorn. All the inhabitants appear to be happy, so I will continue being less anal than most.
I am 63 years old and could well be considered somewhat stubborn.
