I attached a stack of magnetic stones half in half out of the side of my smallest fishtank.
It's eye-catching and the fish don't seem to mind but as I'm cleaning the tank for the umpteenth time since I stuck them in there I noticed that they have absolutely no algae growth. Might be that I mean cyanobacteria,
<shrugs>, I always called the greenish gunk algae.
A quick webternet search shows research being done using magnetism to promote algae growth but perhaps field strength or configuration can inhibit algae growth as well. Magnetizing the filter intake or adding magnetic granules to the charcoal might prolong intervals between cleanings.

[+] you could also feed the fish iron filings to make removing them from the tank easier. |
|
|
Drop a few cow magnets in your filter and post your
findings. I'm always looking for chemical-free algae
deterrents to use in my, um, fishtanks. |
|
|
I suspect it's likelier that the algae don't like the
mineral content of your "magnetic stones". |
|
|
What exactly are they? Are they pieces of
magnetite? Or plastic rocks with magnets in
them? Or what? |
|
|
If they are not plastic and will take the heat, you
could try heating one over a gas flame which
*might* demagnetize it; you could confirm this by
seeing if it will attract a paperclip, and then (if it
is now demagnetized), see if it grows algae. |
|
|
Or take a strong magnet, put in inside a closed
jam-jar, and see if algae grows on the outside of
the jar. |
|
|
[+] because it's experimentally accessible. |
|
|
Sounds like an attractive idea. [+]. Interested is seeing the
follow up results. If you put a magnet on the outside of
the glass could you move the inside magnet around to
scrape algae off the tank walls? |
|
|
Magnetic algae scrapers are well baked, but that's a
different matter. |

There are certain types of plastic that algae and aquatic
bacteria don't thrive on. I don't know what types
specifically, or why, but some of the pieced of submerged
equipment in my 'fishtanks' never attract colonies. I think
that noteworthy, especially considering that the
micropests I encounter are a particularly resilient bunch. |
|
|
No idea what kind of magnets. Shiny, rounded, garage-sale, inukshuk type magnets. I assumed neodymium. |
|
|
Once the underlying mechanisms are understood this is going to be quite a thing. Totally sweet. |
