Re: Vortex or Magnum



I use the Whisper DiatomMagic filter for polishing and like it very much. I
have never used the Vortex or Magnum so cannot compare. It hangs off the
side of the tank, on the inside. As for the diatomaceous earth, if you use
the little packets sold in the fish stores you will spend a lot of money.
Much better to go to a pool shop and buy a large bag, 20 pounds or so, it is
like 50 times cheaper. I do not recall the exact cost but I think it was
arounf $20-30 and will provide me with polishing filtration for at least 10
years.
