i would rather suggest a aqua C skimmer then this. honestly i would rather suggest a sump with an in ( or out ) of sump skimmer rated well beyond but thats just me. a skimmer isnt something you want to skimp out on. its great that your asking around, its also good to read online reviews. you may also want to look for a local reefing club for deals on equipment and to learn new things.
care to share more about your setup?
i also moved your post to the skimmer section to get more responses, you had posted in the reptile section. if your still having issues feel free to click my name on the left and send me a message. welcome to the forum.
