I had one of those nearly 20 yrs ago and it did an amazing job at polishing the water. Like Bob said, it's good for a few hours until it clogs and needs cleaning. Definitely not a 24/7 filter.Vortex Diatom..top notch for water clarification or polishing..but not as a day to day filter.
My brother in law just ordered a diatom filter for his 15 gallon tank.
To me a diatom filter on a 15g is an overkill but it's his moneyI used a Vortex and sold it because I rarely used it. "Purigen" polishes water as good as a diatom filter IME.
IMO, a HOT Magnum (which can be used as a diatom filter) or a UV sterilizer is a better investment because they are versatile. You've got to see the power of UV + Purigen. Water looks like liquid air.
