Help with buying a used tank

So I am getting back in the hobby after 23 years. Seems it has changed a bit! I am probably going to do two tanks. A FOWLR and a smaller mixed reef for the kids room. I really want to do this right the first time. I really want my tanks as low maintenance as possible once they are established. I have a septic system and want to keep my water changes at a minimum. I think I have the very basics down. Now for tank size for the FOWLR I am going 150min - 225 max. I want to know what I should look for when buying used? It will probably be a semi-aggressive tank. Sounds like it would be best to do a sump/fuge for my goals of low maintenance I also want the tank as clean of hardware as I can so that would be a good place. How big of sump needed for gallon size of tank? Also I have untreated tap water at my house can I use that?
Nice Forrum!

Re: Help with buying a used tank

You will probably want to do a 30 gal sump for that size tank. Pack it with Live rock, skimmer and heater/chiller. I don't recommend the untreated tap water, as it will be high in phosphates, nitrates (you can always treat for hard metals and chlorine), which will cause algae and other problems. The initial startup will be okay with tap water, as you will cycle most of that out. I recommend RO/DI autolinking image water for top off (can be purchased at LFS). Also, use that water for water changes ( autolinking image of course). Hope that helps!

Re: Help with buying a used tank

Thanks guys! I am planning on buying a RO/DI system. It is going to be real easy to plumb a water line in. And since it is going next to a big closet I think I will run a 55 sump and be able to have an automatic top of as well.
I will check my tap water bet we have very low levels of metals, no chlorine, and I imagine low on other elements. We have some of the best water in the nation where I live.
I might end up building my own tank it will come out to about 260g. I have a little more room than i thought. Unless I find one the right size used. The large ones are few and far between.
