So im starting on my 30 gallon sump/refugium for my 75 gallon tank to fit my ASM G3 skimmer. I got the tank. I got 4 1/4" Acrylic baffles instead of glass. Stores in my area wanted $15 for a 1/4" - 11 7/8" x 10" piece of glass. I thought acrylic is more expensive but i guess not. Got all 6 baffles (2 spare) for $40 cut to size. Problem is i got them cut to 11 7/8", turns out they need to be even smaller maybe, 11 3/4" or 5/8". Back to the acrylic shop but this time im bringing the 30gallon with me. I was planning on using the far right chamber as intake/skimmer because the tank had a hole drilled in the back so i guess ill use this hole. Then refugium in the middle and return on the far left. I wanted to do it this way so i could minimize head lose on my Rio 2100 return. The flow will go from right to left. After the skimmer will be a 3 baffle bubble trap, over under over so the skimmer section will be a constant 10". Then a single 6" baffle to seperate the sand bed in the fuge from the return pump. The 6" acrylic will have some egg crate installed on top so as to keep livestock in the fuge area. I couldnt figure out which Silicone to buy for the baffles. I thought GE 1 or GE 2. I guess the difference is GE 2 is able to contact water within 4 hrs instead of 24hrs. Anyhow i found a better silicone sealant but its about $1 more than GE 2. Its GE 100% Silicone Sealant for plastic sheets and other plastics. It even says its excellent for marine applications above the waterline and says nothing about preventing mold or mildew like the GE 1 and 2 said. Here are some shots. Ill keep you guys posted.
