Protein Skimmer .. To be or not to be ??

[GreenSpottedPuffer]

I tried it...lasted about a month. The tank looked great and corals actually had better color then now but I hated the maintenance and it was only a month! I can't imagine a long term skimmerless tank personally. Just too much work. Its easy in the beginning but over time once the "new and exciting" part wears off, I think it gets harder to keeping doing water changes. I only had two clowns most of that time in the tank and I still had to do water changes every two weeks to keep the nitrates at 0. It was a 68G, so about the same size as your thinking.

I think if you don't mind a lot of extra water changes (which will cost more than a skimmer eventually) then its a cool way to do a tank but if not, don't bother. Find a tank you can fit a sump.
