bought this clear water 100 algae scrubber a few months ago for my reefer 450 and it’s just too efficient for my tank! Works wonders at stripping n03 p04 and growing algae. Comes with everything needed to operate including the pump, tubing, discharge plumbing and the optional light covers from clear water. Paid $450 for this setup and I’m asking $350 shipped for it with everything. Let me know if you have any questions! Thanks for looking
