I wanted to try and get some feedback regarding an issue I have. I recently set up my 125g tank. With it I pruchase a new ETSS 600 Protein Skimmer. This skimmer is external to my sump and is hooked up to an Iwaki 40RLT pump. The tank has been running for about 3 months and I haven't had any issues with water quality at all so I presume the skimmer is working well. However, the skimmer also requires a lot of attention compared to my Aqua C Remora which I use on my 46 gallon tank. When I say 'attention' I mean that I am still tweaking the ball valve a hair here and there to get the 'perfect' dry foam. I have the 1 gallon overflow and some mornings I will get up and the thing will be full, while other times I won't have a drop in it. I guess I am a little frustrated.
Anyway, after three months I am also running out of space in my stand. I could really us the space where the skimmer and pump sits. So I was considering replacing my ETSS with a EuroReef because the EuroReef sits inside of the sump. Even though I have heard a lot of good things about EuroReef, my LFS
stated that the downdraft skimming that ETSS is better (which I realize is their point of view). However, they also stated that it is better to have a skimmer external to the sump rather than in the sump because of overflow from the overflow cup of the EuroReef skimmer back into the sump (and he gave me a couple of other reasons).
I was hoping that somebody could chime in here and give me their opinions on ETSS versus EuroReef or an in-sump skimmer versus an extrernal-to-sump skimmer, or make a recommendation as to what I should do. Any help would be appreciated. Thanks...
