Just cleaning out a few things: I have a Reef Octopus HOB skimmer (Classic 90) ordered from bulk reef supply for $190 and only used for a few months on a quarantine tank. I'd take $100 for it. I have an ESHOPPS X-160 or X-220 skimmer that sits in the sump, cant remember which one it is, I can check when I get home. Worked great in my 125g tank with moderate bioload. This one is probably 5 years old, I paid between $300-$400 for it. I'd sell that one for $150, one of the 4 acryclic feet that holds the pump inside the skimmer is broken but it still works well since 3 sides are held down. I have a 20-30g sump/fuge? Can't remember what the size is, but I bought the tank from petco and installed baffles to create 3 compartments inside the sump, 1st compartment is for inlet/sock filters/ skimmer, 2nd compartment is a fuge for cheato or snails/shrimp, 3rd compartment is return. $40 for this tank with the baffles. Baffles alone were over $50 on amazon. They are siliconed in place so you can remove them and space them differently easily if you'd like. I also have a litermeter III and RODI system I might be willing to part ways with those also. The litermeter III was over $400 with the additional pump and ATO system included. Would be willing to sell for $250. LiterMeter® III Programmable 3 Channel Precision Dosing System - LM3-115 - SpectraPure Send me a DM and I can send you pictures if interested.
