I wouldn’t recommend that skimmer for your system. It’s way too large of a skimmer in my experience. Especially with the Alpha’s. I’ve owned one and helped countless others here with them over the years. They were/are very under rated and required an extremely heavy load to be consistent. It likely will not be consistent and you will have to run it very wet and deal with occasional overflows and tuning issue. For that system, a Double Cone 200 would be about perfect and would be MUCH easier to tune. Heck, you would get away with a Double Cone 180 for that matter but the 200 could handle a heavier load should you decide to add more fish down the line.
