Penn Plax Magnet Scraper
 

As mentioned in another thread I gave this a try and am in awe. I put this small bladed magnet on the back of my big one on my thick glass in the 230g and it of course jumps around a bit. But all my glass was sparkling-ly-free of coraline in minutes. For a nano, you could just use it as it. Two thumbs up from me. :biggrin:

Great. I need one. Do you just leave it in the water? No rust problems? Has anyone seem them for sale in Vancouver?

No, I wouldn't leave it in the water Sam. Just cause my FW one rusted in there when left in for years. :biggrin:

I just got one myself but I forgot the blade in it.It only took two days before I noticed that the blade started to rust. They work great though!

How ironic that your name is Rusty! :lol:

I have a similar scraper for my mag float, I don't leave it in the water. I have two sets of mags, one I leave in without the attachment for regular cleaning, and the one with the scraper I use when I need to get rid of coralline.

Do they sell these in Canada?

Yes, or at least the "easy blade" which I use is

Ocean Aquatics also sell it.

J&L last time I checked did not

This is not like the easy blade which stays attached to your magnet. That did not fit my magnavore magnet.

Ah, this is a magnet scraper in one.

Is the magnet as powerfull as a mag float 350?
Seems pretty inexpensive if it is!
