Hey guys so ive finally reached the decision of going undertank sump for the 40 gallon. Its currently running cpr bakpak skimmer converted to small refugium and a Aqua clear 70 HOB. Im just tired of the mess of stuff hanging behind the tank looking for something cleaner looking for going the sump route. This will be my first time using and installing a sump so i need some advice. 1 the tank is not drillable so i need to use a over flow . Which over flow do you guys recommend , im also worried about overflowing if the power cuts out. is there anyway to prevent this ? also was looking into the aqueon pro flex sumps, but then i also see alot of nice DIYs sumps on here that look great to. Im looking for a small, well working, low cost sump .dont need anything to crazy, just a skimmer, refugium , and return chambers will do fine. would also like some kind of filter floss or filter socks in there. What you guys think ? hit me with the ideas, opinions and advice!
Thanks
Thanks
