I highly recommend this product. Wish I would have bought this when I first purchased my acrylic aquarium. The wall thickness is 3/4" and works great. I thought it would scratch the acrylic due to its strength but it hasn't. It’s a huge time saver.

I've owned other magnets, this is by far the best. Worth every penny.

These magnets are better than others I could find at my LFS. Quick easy cleaning.

This is one strong magnet. It does a great job cleaning the glass. The only drawback I have found is that it is hard to grip.
Strong bond. Larger than expected. By Jasper on 10/22/2014
Jasper would recommend this product to a friend
I purchased the smallest size, and it's quite a bit larger than I expected. Expect to have trouble getting into tight spots, but very rapidly clean open areas.
The magnet bonds stronger than all other scrubbers I have used. I don't feel like I'll loose the inside piece if I move too quickly. It's secure and scrubs well.
Even works on Coraline By Johnny Sea on 9/23/2014

Purchased the Piranha and it is strong enough to even work through built up Coraline. Like others have said be careful with these they will snap together and catch your finger! If you let these get together without something in between be ready for a workout.
much better than a mag float By mark on 8/27/2014

upgraded to a 1/2" thick acrylic tank, and the largest mag float I could buy locally just wouldn't stay connected, this is powerful and the pad they sent really scrubs well without scratching
love it! By Jennifer on 6/3/2014

I love this cleaner. the magnet is super strong, cleans really well and it has a much better look to it then a chunk of plastic for a magnetic cleaner. It would be kinda cool if they had different wood colors so you could match it to your stand. but it is a much more polished look than the others out there.
works like it says! By reef geek on 3/14/2014

Pay attention before use! By AlexL on 2/6/2014
AlexL would recommend this product to a friend
It works just as stated. Only thing you must be careful with is that the magnet catches from the back side of the scrubber also. And if there's any hard build up, and you swipe, you more likely will scratch your glass. That's how i got a 6 inch scratch in my front glass :(
So please be aware of what side it's on before use.
Other than that its the best magnet scrubber ever used.
Great product By Smallreef on 1/14/2014

I have always had Mag floats; but with this new very thick acrylic tank, it just wouldn't hold on, let alone clean anything. Ordered the Floating Tiger Shark and I have to say I am very pleased; not only with its hold...these magnets are strong, but the cleaning ability, and the extra pads included. I feel this magnetic cleaner will last me much longer than any product I have previously used.
great product and very strong magnet By turbotone on MR on 1/13/2014

I've owned a few different types of magnetic cleaners and these are above them all.. what i would recommend is do not go with the plus 1 method with these bad boys.. get what your need in your size criteria.. these magnets are strong!!! a few swipes and its clean.. i could only imagine a stronger one will be very difficult to move.. definitely would recommend..
Beast mode magnet By Collin on 12/15/2013

This magnet is industrial strength. After a few pushes across the glass, your arm will get tired---and that's a good thing! Lots of power to clean those stubborn algae spots.
I highly recommend adding the algae scrapper with this magnet. Adding the algae scrapper lets you easily scrape away coraline algae.
This is easily one of the best investments I've made for my tank. The upfront cost may seem like a bit much, but in this hobby, you get what you pay for. Totally worth the purchase.
It also includes an extra felt and scrubber pad.
Tip: Keep the magnets apart when not in use, or else you'll stick the felt onto the cleaning pad.
Best magnet I ever owned By Matt on 12/6/2013

I purchased the Piranha Float black Fri/ The magnets are SUPER strong! You really have to put some effort into it in order to get it to slide. It gets the glass clean in only 3-5 passes.
Good product By Shawn on 11/5/2013

These glass cleaners work extremely well and will remove calcified algae from your glass with little effort. I find the pads don't wear nearly as long as I'd like but with magnets this strong it's easy to understand why. I find if I use glass polish before cleaning my glass things move much more easily and makes the felt side last long due to reduced friction.

I purchased the Hammerhead a few months ago and love it. I used a mag float before and with my 1/2 inch glass it would fly off if I went too fast. The hammer has a very strong magnet the will smash your fingers if your not careful with it. I used to worry about scratching my glass but not with this one.
Very good product and worth the high price
AS ADVERTISED. BEST CLEANING MAG ON THE MARKET. By Chicago C4 on 8/21/2013

This product proves you get what you pay for. I don't see myself ever buying another brand cleaning magnet again. Bought the Hammerhead, and it's exactly what you expect -- awesome, plain and simple. Definitely more expensive than others, but absolutely worth it.
Powerful! By Chad on 7/22/2013

I purchased the Piranha Float when I first set up my saltwater tank. The magnets are SUPER strong! You really have to put some effort into it in order to get it to slide, otherwise the cleaner kind of "skips" along the glass and can splash the water around a bit. It gets the glass clean in only 3-5 passes. Other cleaners could take up to 10-15 passes. It is a little bit beefy and bulky, and can be hard to fit into tight spaces, so I purchased a smaller, weaker magfloat to clean the glass right next to the powerheads.
just too powerful for my 50 gal By Joe on 5/25/2013

I pickup the Piranha float, but I just find it a little too large and powerful for my 50 gal tank with 1/4" glass, so I find myself using a smaller mag-float instead.
Strong Magnet! By Dan on 5/22/2013

This cleaner has a super strong magnet in it. To the point where I start to put pressure on the stand (30g). It cleans well, but the price needs to come way down. It's a block of wood with some felt and a plastic block with velcro...
pay attention to the size recommendations By tramboneplayer5 on 5/18/2013

I used to have a 55 gallon tank and was planning to upgrade to a 140 gallon tank. I did not want to buy the piranha and then have to buy the hammerhead a few months later, so I just bought the piranha. I had to insert a washcloth and use the acrylic pad on my 1/4" glass because the magnets were so strong it would almost scratch the glass. Now that I have the proper sized tank for the magnet it works wonderfully. Looks good too.

I picked up a hammerhead for my new 155. I really like the quality of this thing. It looks well made and has a much better appearance than the mag floats.
