Went to work immediately. Works as well as any overpriced skimmer. Easy to use. No micro bubbles. Easy to dial in and tune. Very quiet.

I’m fairly new to reefing and I did a lot of research on skimmers before buying this one. I checked local marketplace and Craigslist ads, compared about 20 different models online, asked chatGPT, etc.. I’m glad I chose this one for a few reasons. I read one review mentioning the noise level, but it’s silent.. I don’t hear anything while it’s working. It also works extremely well. Within two hours of turning it on, it began removing skimmate. It’s easy to adjust even for a rookie reefer. You can adjust the motor speed as well as the air/water intake so it was a breeze to fine tune it. The most helpful accessory is the overflow alarm. If it begins to get too full, the float rises in the skimmate cup, and sounds a low level beep from the controller. That’s awesome, because I don’t check it every day. I’m running it on a level 4 and it’s plenty of power for my 75g with a 30g sump. It fits well in my sump and leave room for other accessories. I was skeptical at first because it is a lesser known brand and not many reviews exist, but I’m glad I went with it.

JUNE 14TH, 20025 update// I Purchased a second MagTool skimmer (N130 Plus) with the puchase of a new sump. LOVE THE Overflow kill switch thats included. I added a second switch, still connected to my Neptune Apex. Still rate this a 5 Star item. There is a buzz humming from the pump at first, but all you have to do is put a small amount of pump grease on the impeller body and the pump becomes SILENT...//purchased in September 2024 (N170) and waited to give my complete review 90 days (Jan 2025). This Protein Skimmer (N170 Plus) is on a 108 Gall9n Mixed Reef System and stands with the rest of well known and top performing skimmers in my experience so far. Quietness is my biggest factor when picking a Skimmer and this has passed. There is a squant and faint humming sound from the pump doing it's job. Another factor is the DC control which give you the ability to crank it up or down. There is a inbed timer for the skimmer that will help prevent skimmer overflow once it is turned back on after feeding or maintenance for example. That timer can be overridden if you chose, but it is a nice included feature. The air value is very easy to operated, mine is attached to an Air Scrubber to help increase my ph, (8.40 during the day and 8.20 at nights). Skimmate is nice and thick with the help of my Automated Reefmat, my aquarium water is crystal clean. I have my skimmer controlled by my Automated Aquarium.controller... Neptune-Apex System..really great addition that has worked flawlessly since I installed it as a replacement.

This skimmer works well. Especially for the cost. Good speed. The variable knob control is nice but touchy. Started collecting skim mate quickly. Fits well in small spaces. Easy to install. For its size it has decent storage capacity. Minus one star for the discharge tube. It is very rigid. This makes it difficult to position the skim cup to drain it easily. Not a big deal. Using on a 20 gallon sump. Had to use a riser for proper water height.

I've used several smaller skimmers for nano tanks but just completed setup of a 50 gallon saltwater tank with a sump and needed a larger skimmer. This was not only the perfect size to fit in my sump, within my limited cabinet space, but setup is very easy and it started skimming properly immediately! Zero break in needed! I love the adjustability and drain as well. Lastly, the air inlet for the pump comes with the same diameter hose as my CO2 scrubber which is bonus. Some of the other skimmers don't even have a way to connect the air inlet to a scrubber which is another reason I went with this one. This skimmer is fully serviceable with four nylon screws in the base for disassembly. I absolutely love this skimmer (did I say that already?)

I saw this on Amazon and was very hesitant to try it because it wasn't a known brand. I was about to go crazy with a Red Sea 300 skimmer as it was overflowing and not skimming all the time. I received the skimmer and was immediately very impressed by the build quality. It's very well constructed with quality parts. The best part is the DC motor and the ability to adjust the flow. I was having to put spacers on the bottom of my sump to raise the Red Sea skimmer or it would overflow. With this skimmer, I was able to drop it in with no spacers and it works perfectly. I currently have the controller set on 4 and it's perfect. The air intake adjustment works so well and is very easy to dial in. It's super precise and only takes about a 1mm adjustment to make a difference. I would recommend this to anyone as I run a 100% Acropora tank and it has the very best of everything with no expense spared. This skimmer is better than some 1k skimmers I've tried. It also is almost an identical copy of a Bubble Magus by the way :).

The media could not be loaded. I've bought three protein skimmer in the past and they all seemed to fail on me one way or another. I recently picked this up and can tell it will last. Highly recommend and I'm already getting skim after a week of use. With the right bubble trap in my sump I am not getting micro bubbles in my tank either. It fits perfectly in a 10 gallon sump. I do wish the design was more functional for taking off the cup because it's on there pretty tight but the hose works great for emptying the cup.
