  • Easy to set up and get working.
Size: N100 for 50-100Gal
Excellent skimmer. Not as finicky as others I have had. Set it up, small adjustment and has been pulling out nasty water. Love it! I do have the variable speed pump one, and feel that is definitely worth the extra $

  • Great piece of equipment for a reef tank!!
Size: N130 for 105-135Gal
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. ... show more

  • Nice Clean Sleek and Quiet Skimmer N130 Plus
Size: N170 for 135-185Gal
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. ... show more

  • Does the Job
Size: N100 for 50-100Gal
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. ... show more

  • Excellent value
Size: N170 for 135-185Gal
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.

  • Had high hopes
Size: N100 for 50-100Gal
It quit working after 6 months. I'm trying to decide if I want to get the bigger version for my 125 gallon or try a different on brand. I had high hopes for this product.

  • Does have a great shut off overflow system
Size: N170 for 135-185Gal
Works great as intended and is super strong, adjustable too! , but I’d kinda bigger than I thought, I didn’t read dimensions but my 120gallon sump is a 30gallon and takes up a good chuck of my sump, fits but have to assemble it under the tank, so it’s possible! And easy to use!

  • This works with any water level. Fantastic equipment.
Size: N130 for 105-135Gal
The media could not be loaded. I'm running this 130 Plus on a 125 gallon display tank with a 25/30 gallon sump. I suggest you guys get the 170 if you have a 125G tank. This N130 doesn't cut the mustard. Would buy the brand again though. Edit: Dear God what a pain in the ass to clean. Whoever decided to use plastic machine screws should have given the threads more room to wiggle/move. Taking this thing apart for maintenance makes you rethink your decision on buying it. - 2 stars at the minimum. Make it disassemble easier text time. Also you can't use a screwdriver because they're freaking plastic screws so the screwdriver just eats up the plastic!! Frustrating as hell y'all. ... show more
