Thank you all for such good replies. I have a few more Q's:
It is tough to find a good skimmer that fits both in height within the cabinet (30" inside ht) and within the return sump (12"x12") of the wetdry filter box that we have. Currently, the Vertex has too big of a footprint. I am leaning towards the:
Protein Skimmer 9005
AquaC EV120 Protein Skimmer w/ JG Fitting + Rio 2100 Pump
Regarding the power heads, I am thinking of getting 2 K3's or K4's. Any preference?
Also, over the last few days I getting development of very bright green algae (I think). Is this okay - or is it something else.
AND I getting very little (<1/8") circular white things stuck on the back of the tank and even a few on my turbo snail. they are a little tought to chip off. Anyone know what this might be?
