Thanks Josh! 4 inches will allow me to run my Eheim hobby pump or even my DV Waveline 6000. After reading and learning, there are 2 different refugium sumps!
The R-100 which is yours. Then the ADV-100 which is more money, and a different layout alltogether
Apparently, the ADV-100 has a 5.5 inch return pump chamber, and you can see it from the front. Its the last chamber on the right.
The ADV-100 also features built in probe holder as well, which I do not need. I am thinking the R-100 will suit me just fine, and its about 70.00-80.00 less in price.
I am really liking this sump and I think I am going to go for it!
