My reef. is 1900 liters, hevy stock of sps, I have to replace my old etss 800, that these are the options:
AP 1003 (Deltec)
300 External (Bubbles King)
or
HSA-3000 (Marine Technical Concepts)
MR-7 (MRC)
I've never used either, but looked at both bubble king and deltec and they seem roughly comparable. The high-end euroreefs that recirculate might be getting into that territory also.
I'm still waiting for my Barre skimmer ordered may 7th. :lol:
