To eliminate confusion, can the people who have opinions about this say yeah or nay to the following questions so he knows the consensus as to how to proceed?
Decrease photo period (and maybe even lower in the future)
Remove wet/dry
Get rid of tangs
Shut off sump (skimmer can run directly on the tank)
Buy a Fluval canister and run carbon, nitrate sponge, and silicate
Start looking at prices for a heavy duty skimmer for the future
Test copper if you have a test kit, if not, maybe this is lower priority
Maybe do a 20% water change after all this is done to speed the process
NO FOOD.
Please quote in you response yeah or nay. I think it will help him make up his mind, since a lot of good reefers are contributing at this point.
