mag float

They work great on some algae, but don't do much against green spot or other harder algaes. If sand gets under the magnet it can scratch a glass tank.
 
ya they remove the easy stuff, but you will still have to do some tough scrubbing from time to time.. but def worth it... i got a little one for my 29 and its junk,,, just not enough power to stay together....so i use big one for all my tanks now...:dance2:
 
I got one and was not impressed. It was supposed to be "acrylic safe" but scratched hell out of the SO's tank. (lfs guy says that many tanks called acrylic are actually just plain ol' plastic, so this may not have been entirely the mag-float's fault.) And it only cleaned a little strip like 1/4 inch on each pass, so it was a substantial amount of scrubbing to clean even one wall of a 12g.

A fuzzy plastic scrubber pad works much better, imho, besides being cheaper. Yes you get your arm wet. /shrug
I use one on my acrylic tank with a piece of tailor cut micro-fiber cloth embedded with Novus acrylic polish number 2 or 3 depending on need. The polish stays on the micro-fiber even under the water only bleeding slightly but never hurts my fish at all and polish/cleans the glass very well. However only the medium or large mag cleaner has enough strength to firmly hold "thin" microfiber cloth sandwiched on the face of each magnet to prevent the scratching of acrylic and hold polishing abrasive in the micro fibers.

green pads ftw, baby! that's my trick. i love my mag float..... buuuuut... after some time in the tank the rough pad i typically use inside got a little gummed up and didn't work as well as new. that's when i cut a piece of green pad the size of the mag float surface and stuck it on there. glass comes clean in record time with half the effort. laziness has it's benefits. :D

the bottom couple inches is best to use a scraper to keep the mag float out of the substrate so things don't get scratched.

don't try this at home folks.... if your tank isn't glass... you folks have to put the time in, lol. acrylic is pretty but beware of your zipper during tank maintenance... and anything else that touches it (like a 3 or 5 yr old).
 
mag floats rock, except for on hard algae.




tank, stand, filters, lights - $(insert insane amount of money here)

plants, sand, fish - $(insert more insane amounts of money here)

realizing you are using your maxxed out credit card to scrape hard algae - PRICELESS!
 
Love the mag floats..
 
I appreciate all the information. I plan to get one for each of my tanks, 30, 55 and 150 glass tanks
 
I love the Mag Float but don't get near the bottom if you have sand as your substrate since it will scratch with even one little piece of sand.
