also, could you recommend some brands? and how to install it? i don't have any experience with these. thanks
I bought a nextreef MR1 and a maxijet 1200 to power it. I love it, but there are cheaper ones as well. I would buy bulk GFO from Bulk Reef Supply. Cheaper than Phosban and works great.
By the way, you want the GFO barely moving not tumbling or it will go back into your tank. I installed a ball valve on the intake hose and the GFO just barely bubbles. It took about a week before it really kicked in but now my glass is always clean even when I leave the lights on all day.... just a swipe or two over the weekend.
ALSO - DO NOT Fill it up. Your corals are used to the high phosphate levels you have and reducing it too quickly will probably kill them. I started with 1/4 full for a week or so, added another 1/4, for a week or so and then finally another 1/4. Keep in mind my system is close to 600 gallons so you may need less than that.
NOW, those things said, I am also a notorious over-feeder which is probably why I had high phosphate in the first place. and I am sure someone will chime in and say find out the cause of your high phosphates and fix it.
THEY ARE RIGHT TOO. Fix the problem. Good luck.
