Wait, I'm a bit confused, I have been running twin xP3s on my 60g and have not been realy happy. These filters are $140+ each. I tool one off and built a 10g sump and fuge, with a PVC
overflow (not drilled) for $90. The pump being the most expensive item of 60$ for a 700gph. I built a 1inch overflow and I am getting 350+ gph
out of my sump and refuge. Also notice I set it up as a top skimmer, no more proteins floating in my tank!
you made a good choice, but they are not as expensive if you make one, unless you buy a pre built one. I have no "arts and crafts" abilities at all and I made this work!
I am however interested to see a pic of yours when it's set up!
Don't judge, I added new sand and it clouded up a little.
