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
Sandra would recommend this product to a friend
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
monkiboy would recommend this product to a friend
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
Matt wouldn't recommend this product to a friend
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.
The best cleaning float money can buy By Edward on 1/28/2013
Edward would recommend this product to a friend
Not only does it clean better (stronger magnets) than traditional mag floats, but it also looks really classy on the tank. I leave it on the front of my display along the sand bed - it looks that good! And the fact that it comes with spare/replacement cleaning pads is a really nice touch! Don't look elsewhere - buy this for your tank.

Not too happy... By Scott on 1/7/2013
Scott wouldn't recommend this product to a friend
After paying almost 100 dollars on the Tiger Shark and only having it for a couple months and the outside liner started peeling away leaving a sticky residue all over the outside glass of my tank.
I have since taken the liner off and use a small soft pad there and it works famously, but I shouldn't have to "rig" an item that costs this much after a couple months of use.
Best Algae magnet I've tried By CY on 12/14/2012

I used the usual MagFloats and tried the Magnavore as well. I always go back to the trusty ALG magnet. Best balance of quality, performance and price

takes all the algae off my tank in one sweep, only problem is the magnet is way too strong that it is giving my arm a work out on my 29 gal tank. but cleans so much better than my mag float

I'm new to the hobby. As you know, constant water changes, putting in live rock, figuring out the equipment, etc., has left little time to actually enjoy my work. I've cleaned the front of the tank 4 or so times with windex, but it was always smudged. I got this on a whim and it is amazing. All my work is viewable crystal-clear. Trust me... reward yourself and get this. It's not a necessity, but makes the tank the work of art that you worked for.

This cleaner is by far the best on the market. The magnet is crazy strong and the optional razor blade attachement makes getting hard algae off very easy. My tank has never been so clean!

Other magnetic glass cleaners I've had in the past aren't strong enough to stay together and do a poor job of cleaning. The tiger shark magnetic glass cleaner is nothing like those. The magnet is strong enough to stay together through thick glass and has a tough cleaning pad for algae. Don't waste your time looking at anything else.

I don't know what I would do without this! I have a 210 gallon Marineland and this is strong enough to hold on my thick glass. I bought the Tiger Shark and its perfect. I wish other parts of reef keeping were this easy.
So much better than the cheap ones! By Casey on 8/29/2012
Casey would recommend this product to a friend
I've always ran the cheaper magnets and I aquired one of these with a tank I recently purchased and all I can say is wow. Not even on the same level with the others. It grabs/cleans way better than the rest, yes its a bit more pricey. But honestly, after using it, I dont think I could buy a cheap one again. Worth every penny.

Love this cleaner. Works great and it's fun to try and get it around corners. Makes cleaning the glass easy and fun.
Must Have! By McKay on 8/10/2012
McKay would recommend this product to a friend
I would consider this a "must have" item for anyone who takes this hobby seriously. Makes light work keeping your glass sparkling clean. Only heads up... be careful around the gravel line - especially if you have fine sand/gravel. These magnets are extremely powerful, and if anything gets caught in the pad it's very likely to scratch your glass. I usually use this to a half inch or so above the gravel line and use a kent scraper for anything below that.
Just about worthless By Nathan on 8/3/2012
Nathan wouldn't recommend this product to a friend
I really wanted to like this magnet. It's outer wood shell is stylish and it floats. The problem is for my tank it's just too powerful. I have a 55g glass and the magnet skips around like a 1950's record player. There is no way to get it to slide across the surface of the glass.
I've tried going up, down, fast, slow, etc. It just skips. I'm assuming that although it's listed for my thickness glass, that it's just to powerful. Oh, and keep your fingers out of the way of this thing. It looks like it could do some damage if you got your fingers caught in between the two magenets slamming shut.
Now I'm out ~$50 and don't have a functional magnet.
