I purchased the Piranha and this is the best algae cleaner I have ever used. Very strong magnet and well-built well worth the price.

Hammerhead works well with a very strong magnet however do not use close to your gravel it is very easy to scratch your tank with gravel which stays on cleaning pad....

It will clean your glass, however, it is one of those to each his own. For me it is way to strong and extremly difficult to move around the tank. It takes 2 hands and it has nothing to grip, thus I have gone back to me old class cleaner.

Got a hammerhead for my 90g tank with 1/2 inch glass- way too strong, grips too hard so it stutters when it moves along the glass.

This is a great product. The magnet is very strong as advertised. It helps reduce the amount of time for cleaning the tank and I only have to clean the tight spaces by hand

I have a Piranha and a Hammerhead float. Both clean the glass without scratching and work very well. The only reason for not giving a five start rating is they are a little hard to grip. If outside block was a little thicker it would be helpful.

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.
