New fully automatic backwash pond filter, smart koi pond filter.

When it comes to pressurized pond filters, there are many reasons why you don't want to use sand.

It will require larger pumps to run, which can result in higher energy consumption.

Because the sand is so fine, fish waste can build up on the surface and clog the filter, making it unusable.

You will need to backwash your sand filter daily to keep waste from clogging it.

If the sand does clog, it cannot be backwashed properly and must be cleaned by hand.

Sand provides poor living space for beneficial bacteria and therefore has no biofiltration properties.

So now that you know why sand can cause poor filtration systems, you can still use other media in pressure filters. Beaded media and microbial filter media require less energy to operate, are easier to maintain, and have a greater biological surface area than sand. Just make sure you install a screen to cover the outlet so the lightweight beads don't get washed away during the backwash. I recommend just enough to remove dust not beads.

When you convert a pressurized sand filter to a biological unit, you only want to fill the tank half way up with the biological filter media (I recommend the filter and UV pack). Next you watch the flow rate through the filter, if the water is moving through the filter too fast then the filter is not bio-effective. I do not recommend connecting the pump directly to the filter. Instead, you want to use a flow regulator so you can better control the pressure. When running in filter mode, the water flow is slower and the flow is increased when backwashing. For transportation, I recommend emailing and asking for some guidance on what you need to drive. Before you call, please have the following information ready: tank diameter and height.
