I am needing some help with some plumbing ideas for my 90 RR tank. I'm not that good or familiar with using PVC piping and don't really know how to go about piping my tank. My plan for this tank was to use a 20 gal long that had baffles in it as the sump, but after thinking, I though it would prob. be better to just use the 100 Gal. Plastic Stock Tank that Rubbermaid makes as a sump instead. Now to do this I know I need to pipe the tank over to it as well as do something for the return. Now like I said I'm a little dumb when it comes to this kind of work so I don't even know where to begin or what is the best to use. Once I got this all up do I just drain it all into the sump or into some kind of prefilter. I didnââ"šÂ¬Ã¢"žÂ¢t know if its alright for all the crap to just drain into this. Also should I just fill it with live rock and let that be my main filter? I want to purchase a big skimmer to put inside the sump. Any help would be great. Pictures would do best for me since like I said I'm very PVC illiterate.
