Hello- I am new to the hobby and beginning my tank build. I had originally purchased a COR-15 to use on my Reefer 425XL but am worried after reading some threads where others have the COR-20 in their smaller tanks that this pump won't be big enough. I had a Reefer 425XL 88 gallon DT and 112 gallons overall with sump. I was just going to put the return pump in my sump and build 1" hard PVC tubing as the return so I could create a couple opportunities for reactors or UV if possible. Will the COR 15 be enough to do all this? I am worried I ordered the wrong size but really like the idea of only linking using the 1link system to my Apex. Any advice would be greatly appreciated!
