Maxspect jump Oct 1, 2022
I have no idea what some reviewers are talking about. This is the best skimmer I've had no micro bubbles. Even during the break-in period when I bought it I couldn't believe it and it's quiet it's an excellent design has been running consistently 8 months all I clean is the collection cup it's a Workhorse. For me After a water change the skimmer gets excited I run It Wide Open the next day I put it to the water line where I like it runs beautiful. It's very heavy duty and for 300 you can't beat it.
Some good points, but in the end not consistent Jun 20, 2022
I bought this to replace an extremely unreliable skimmer from a now-defunct brand, and was tempted by a sale price. Good points: relatively small footprint, easy setup, DC motor, quite large collection cup, nice controller, and the dual pump sounds good in principle. However, all that is overshadowed by performance problems. It is set up correctly, and I've played with water height and other factors a fair bit trying to improve things. It seems to pull relatively little air as compared to my other skimmers. I suspect (and I'm guessing here but it seems logical) that the two small pumps just don't pull enough water each to in turn suck enough air in there. As a result, performance is just OK. Second, and more serious, its inconsistent. In the first month of use, it went "nuts" and started overflowing water into and over the collection cup five times. No clue why, I carefully inspected it each time and there were no clogs or other visible issues. For some reason it just stopped pulling air for the most part, leading to too much water flow.
In the end I'm sorry to say I'm regretting the purchase. I have four skimmers in various tanks and the other three, while more expensive, have performed perfectly needing only routine cleaning to keep going. Should have gone for what I know.
Good for 100 gallon or less Mar 16, 2022
I my view it is good for 100 gallon or less. Had no idea how small the size was(my fault). Went by what Maxspect claimed. The reactor is so small that the pump takes up almost all the room and very little dwell time for the bubbles. They are really small bubbles but the output is small and really fast. have a 180 invert take and just not big enough. Well made construction wise but wish it had been rated more accurate.
