The aqualifter is a life saver. It kept siphon on my system great until it burnt out, and I then almost overflowed my DT.
Either way, a nice sump setup is what is needed for a good reef. It gives you space for your skimmer and fuge. Along with that you can put anything in there from heaters and so on. I'm planning on putting all the above back into my sump once I fix my issue, which has a dual reactor w/ GFO
and activated carbon with the addition of an algae scrubber. I've come to the conclusion that it is turning into overkill, but I really like the DIY projects.
