Sump redesign and adding Reefmat 1200 Looking for thoughts

[William Norman]

So I am upgrading to a IM 200 EXT. My current sump is a 75 gallon marineland that I built into the sump. The dimensions are L 48.4 W 18.4 H 21. My first thought is to reduce drainage plumbing and reduce resistance is to put the drains straight down into the middle of the sump. Essentially the area that is the return today. The second is do I really need the bubble trap ? Third is if I moving everything around, restructure for auto filter roller. After researching it seem the safest bet for a good experience is the RedSea ReefMat 1200. which RedSea state requires 8.1" x 17.3" (5.2 is for hose space). My first reaction was HolyS$#t that is a lot. Since the width of the inside of my sump is 17.2 it might just fit.

Current Layout

Do you all think I need a bubble trap prior to the new return ?

Should I seperate the skimmer and media from the drain and Reefmat ? I am thinking it would provide more control for the skimmer.

Thank you in advance for use of your brains and experience.

I cant answer all of your questions directly but no, no need for a bubble trap as you will plumb the overflow/inflow from the tank directly to the Reefmat… the outgassing will occur in the Reefmat chamber

I had a space crunch with my old sump so instead of the convoluted hose I used st8 PVC 1” with a mm to inches adapter and a street el that fits snuggly into the side of the 1200…Ill have to see if I have pics

Added: opinions may vary but IME with a filter mat I see no upside in sump chambers, except maybe for the return pump to isolate it from the heater so that stays submerged ( but I almost never outfit with heaters anyway)
