Question for Acrylic folks

[Larry Grenier]

I already asked about getting one of those basic piece-o-plastic on a stick scrapers but what about a magnet scraper? (I plan on using both) The acrylic is 1/2" thick. What do you folks use and/or recommend.

Thanks

Larry,

 

I'd just use one of the Magnavore magnets for 1/2" acrylic. I would just load up on extra pads when you get one. This in conjunction with one of those plastic scrapers should serve well.

my nano jbj came with a magnetic scrapper just don't use one for glass and don't get it anywhere near the sandbed:)

I really like the Magnavore ER 6. Extended reach, strong, and it floats.

 

The 8 and 10 are good, you can really scrub 3/4 well with them, but don't have the extended reach, and may be overkill for 1/2.

I'll go against the flow, I've used both the Magnavore 6 & the Algae Free Great White - both scratched the tank. As does the Kent "Pro Scratcher" when used on the long handle.

 

I've only found a process that keeps from scratching -

 

1) doubled up acrylic safe pad on the inside magnet, used by hand

2) Scrub more stubborn stuff with a Dobie (kitchen aisle, 2 pack 3M product)

3) Scrape coraline spots with the red blade from the Kent unit

 

 

FWIW - I have 3/4" thick acrylic which requires heavy duty magnets, these heavier magnets may be the cause of problems I've had.

We now use http://www.pentairaquatics.com/products/de...algae_pads.html .

 

(We used to use a magfloat, http://www.magfloat.net/telas/pagina.php?id=5&idc=3, but a few bits of sand grit got stuck in the cleaner and scratched the tank.)
