Protien Skimmer ???

[Lance]

I went sumpless (ran a Fluval 405) on my 90 gal corner tank for several months before I put the sump in. I found it easier and much less work keeping the water parameters decent after the sump was installed. Skimming keeps the water so much clearer with fewer water changes. I still use the 405to run carbon. Personally, I would never go back to keeping a tank without a sump and skimmer. Hope this helps.
