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 have only used this twice so far and it works great no issues straight out of the box ready to go.

Gets the pink coraline algae off pretty easily. never had a mag work this well. I also bought an add on scraper but haven't had to use it.
Very nice By Don on 3/27/2013

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.
Great on my 3/4" acrylic By Mike on 3/25/2013

I bought this cleaner for my 3/4" thick acrylic display tank. The magnets are strong and give a very good scrub to the inside of the tank...glad I spent a few extra bucks for this model. Much easier to keep up on my maintenance, I was getting tired of trying to clean in 30" of water from above with other tools!
Get's those stubborn bits off! By Sandra on 3/10/2013

An excellent glass cleaner. Very strong magnet that is capable of removing those stubborn bits of algae on the glass that aren't touched by the cheaper versions. Also, esthetically more pleasing than a hunk of plastic stuck on the outside of the glass. Bought two, will buy another for my 3rd tank.
actually does what you want it to By monkiboy on 3/9/2013

excellent product. comes with extra pads for both sides of the glass (smooth sliding and algae destroying. VERY strong magnets. does the job. don't be overzealous and get larger than needed. use the suggested ones for the glass thickness you have otherwise you'll be getting a heck of a work out and putting your glass in potential danger.
really enjoying this product. it is my second!
Good magnet By Matt on 3/6/2013

Good magnet, not great. Much Stronger than a magfloat, but does not seem to clean any better. This float still does not remove stubborn coraline or other thicker algae. The strong magnets are not really needed to remove the types of algae this scrubber handles well.(film algae)
I'm using on 1/2 inch acrylic so it may be slightly undersized. I like it, I'm just not thrilled, maybe my expectations were just too high.
hamer head mag By peter on 1/28/2013
peter would recommend this product to a friend
I have the hammer head mag. I had what I thought was a problem. I emailed Mark told him I picked up the Hammerhead at brs and his service was second to no one !!! I see why BRS sells the Algea free mag and why I will never think at all about buying any thing from them again , and yes its great also buy the scraper blade it takes any thing off.
