Re: [GSAS-Member] Going Canister?

["Clifford Miller" <clifford@clevergeek.com>]

Since there have been some good positives mentioned about canister
filters, I thought I would mention one thing I don't really like about
them - failure type.

If most kinds of filters fail, they simply stop filtering.  I've seen
canister filters (especially ones using bottom-drains, or that have long
in-tank extensions) break in ways that meant a flooded house and a tank's
worth of dead fish...especially the kinds that use "quick connect"
attachments to make it easy to remove the canister.

It's never happened to me (and I have used a canister filter), so I'm not
saying they are likely to fail when properly set up, but I'd be curious to
hear if any of the canister-filter users in the group have ever had
issues.

I'd also add that I've had good luck using open-celled foam pads from
Joann fabrics for my DIY sponge or wet/dry filters. (and polly pillow
batting for media, and polly cloth for nets/breeder boxes). It's quite a
bit cheaper than most of the things I see in the shops, and works well. (I
rarely do water chanages, and never seem to have problems).  If you get
the local coupon fliers, Joann's regularly sends out 50% off coupons,
which make things even cheaper.
