Hey everyone! I'm upgrading my entire reef system to a larger tank, and have some lightly used equipment for sale. I'm looking for local buyers before advertising on the selling forum. Here's what I have pictures of right now: Apex Classic controller system, extra EB4, and Apple AirPort Express wireless router: $575 obo comes with everything included in the Apex Classic system EXCEPT the ph probe original boxes included Neptune DOS dosing pump: $250 obo includes original box and everything that comes with a new DOS NOTE: I have modified the pump head outputs to accept 1/4" compression tubing. This completely prevents leaks, which are common with the stock connections SMART ATO micro: $100 obo includes original box and everything that comes with the new ATO NOTE: the tubing has been cut shorter than the 6' that comes with the new ATO BRAND NEW Neptune 1/2" flow sensor: $50 I also have a 24" x 4 bulb ATI Dimmable Sunpower T5 fixture (perfect condition, original box, 7 bulbs included, $375), a Reef Octopus Classic 100 HOB protein skimmer (perfect condition, original box), and a Marine Depot 600gph overflow box (brand new--never used). Let me know if you have any questions or if you would like to see photos, etc. Thanks!
