I bought these thinking I was going to use them but.....turns out I just want to change my water. I have sold 2 now I have a 3rd one for sale. This one has a container and all the plumbing (hose and shut off valve) that you could ever need.Im asking $70 or a trade or a combo of the 2. I need salt and was thinking about trying salinity again. Um corals are getting tough because i am running out of room Unless you have a brain (no favia) I want one of those but any way hit me up. If you must have a picture just post saying that you need one.
