I'm using the fresh stuff, crushed and used immediately.....I'm reaallyy tired of the smell of garlic, it permeates everything :lol:

They're hard to find but apparently a diatom filter can remove ick, well the free floating stuff anyways. not sure if you could eventually get rid of it that way?

well, I think a diatom filter is as useless as a UV filter in terms of figting ich. You have to some how get all the free swimming ich to get pass the diatom filter or the UV filter before they attach to fish in order for them to work, assuming the filter is the right size with correct flow rate. That is not possible. You fail even if one ich parasite finds the fish before it goes through the filter.

This is a brand new UV sterilizer. 35 or 36w. I think for your tank, just screw on the clear plastic nozzles, add a couple of short pieces of vinyl tubing and add a powerhead in the display tank. You could stick it in the sump, but I think if you somehow position so it stays on your display tank you should be better off. Maybe zapstrap it onto something. Even a MJ1200 would work but its big enough you can go with more flow.
