Re: NFC: Pressure (prolly off-topic. :)

I don't know what pump you have but if you look at the literature on them in
the various pet supply catalogs, some of them are rated for circulation and
some are rated for pressure situations.I'm sure the Rainbow filter would be
in the later. Iwaki pumps come highly regarded from my crusty friends
(saltwater buddies).
