Hello!
I purchased 3 PureFlo Micron (50) Filter Pads by CoraLife 18x36. (I didn't want to run out anytime soon

) I added it to my wet/dry filtration. I cut it to fit. It states on the package that it may need to be rinsed frequently and it's reusable. I have well water and no
chlorine issues so I'll rinse it under tap water as I'm not counting on this pad for biological purposes. I don't count on any of this media in the blue tray for biological purposes. I change the batting material every 5 days and I rinse the course pad every 5 days too. This prevents clogging.
I placed the micron pad on the bottom of the blue tray, which is above my blue bio balls. However, since it may clog quickly I've placed my really course filter pad and a layer of batting material (I use as floss) on top of it. Maybe this will help prevent it becoming clogged too quickly.
I'll update with results in a few days. I've never used the micron pads before. I'm anxious to see if there is a difference in my water clarity. If there is a significant difference then maybe I can go longer periods before using my diatom filters (which also filter to the micron.)
Maybe I'll get a photo of the new white micron pad before and after use.
