Has anyone used one of these? I have been reading about how you can use a Magnum 250 with diatom powder to clean to 1 micron. This would rid the tank of parasites, etc. and micro polish the water. Is this something worth looking into? Are parasites problematic enough to justify the expense ($50-60) and trouble to set a micro filter up?
I guess since I have a few fish in the tank too I worry about parasites and tanks "bugs". Am I being paranoid? Does the canister filter do a sufficient job to make this a non issue?
Thanks!
