Review by Richard L. Elias for Sunterra 337106 Prefilter Box for 500 Gallon Pond Capacity, Black

This filter box is a pre-filter that draws water through two foam pads — a coarse filter, then a fine one — before it is drawn into the pump. My Sunterra pump includes another filter inside a snap-on housing, so the pond has three filters in all. The box filter is effective but clogs quickly. The top is held on by four screws. To clean the foam pads, you must disassemble it. Awkward. Some kind of snap-on top would be more convenient. Also, my Sunterra pump has a threaded outlet which is designed to be used with a Sunterra diverter valve . . . more than I needed or wanted! (I have a small pond.) A trip to a hardware store yielded a few plastic plumbing coupling that allow me to snap a hose onto the outlet with a quick-release coupler . . . very convenient.
I had drained the pond and refilled it before installing the Sunterra kit. It wasn’t possible to drain it entirely because of the fish, however. The filter got clogged quickly even with new, clear water — well, clearER than it was! Yesterday I drained the pond again, more thoroughly, and decided not to use the box prefilter but just the pump with its built-in filter. I can get it out by snapping off the pump housing. If it doesn’t clog for a week or so, I’ll try to add the prefilter again. If it does clog, I’ll just go with the built-in filter.

After use for about a year there have been no problems with this product. Plastic didn’t crack yet.

One of the good things about a small pond is that you can use a simple little submerged pump and a simple little filter box. This box works with the Sunterra pump (reviewed also). There is a course filter on top, then a finer inner layer. They are easy to remove and clean and should last a very long time if maintained at all. There are little holes punched out in the filter for the hose to go through and you can see the hole in the top cover.
In my review of the pump, I point out the problem of running the tube so that it doesn’t arc way up in the air. Also, detaching the tubing is not all that easy, so I suggest making little razor blade slits in the filters, from the hole to a side, so that they can be easily removed for cleaning without the hassle of playing with the tubing connections.
I placed a couple of rocks on top to hold it down and to hide it some. Just don’t obstruct too much of the filter.
This is a simple, economical way to deal with mounting a pump and filtering a small garden of fish pond. I recommend it.
