Anthony,
I just wanted to thank you for your assist in my design of my new sump. I had to go with the 29 due to space limitations, but it sure eased my mind about a flood, lots of extra room for water:
I unfortunately had to put my HOB skimmer into my sump as I didn't want to drill the 29 for the input pipe, so my cheato area is smaller than I want:
But, now my skimmer pump draws water from the top 4 inches of the water instead of the bottom 1 inch and in eight hours I already have this:
The picture doesn't show it, but it is dark green yummy skimmate. I also had 1 inch of dark green skimmate in my overflow bottle in 8 hours, looks like I'll need to empty my skimmate every 1-3 days, much better than the 3-5 days it took to get one cup with my old refuge/sump.
THANKS FOR THE INFO!
Brian
