Hi everyone, My eyes were too big for my life, so I set up an ~200 gallon system ~2 years ago. That proved to be more than I could handle, so I tore it down and now I have these tanks for free. I cleaned them with pressurized water, but did not use acid to remove coralline algae from the backs. These were reef tanks and only contained reef stuff (no copper, etc). I'd love it if whoever takes these might eventually give me some softies/zoas/inverts for a small tank I'm setting up at work as a replacement, bit it isn't a requirement. Here are the pics: All three tanks; the two 75s are drilled such that water is returned from the sump into the left side of the left tank, flows through two bulkheads on the right side of the left tank, into two bulkheads on the left side of the right tank, and through an external overflow on the right side of the right tank back down to the sump. left tank: Right tank: Rear of 75s: External beananimal style overflow (all pipes 1" inner diameter): Overflow from the inside: Overflow from top: 40 gallon sump with two compartments and triple baffle: Tanks come with diy glass lids and all the plumbing I used (including gate valve for control of the overflow as well as a sump manifold with hookups for 2 return/feed pumps and lots of different types of reactors). I can also give you some powerheads and heaters with the tanks for free. I can sell you some Jebao controllable wavemakers (RW-8s and WP-40s) as well as led light fixtures, return pumps, calcium reactor, CO2 tank, skimmer, etc, but those will be posted later in the for sale section (or feel free to reach out to me if you want them). First I have to get rid of these huge glass boxes! PM me if you want the tanks. I live in North Oakland near the intersection of Alcatraz and Telegraph. Thanks for looking!
