Matala BSTPII Biosteps II Pond Filter for Ponds up to 2,700 gallons with 6 Filter Pads (2 Blue, 2 Gray, 2 Green)

Wish I had bought this filter system years ago. I love it. Cleared the water up in my koi pond in less than 24 hours. Such an easy simple system to put together and clean. Well worth the money. Filters are going to last a really long time. I used to have the round bio pressure filter system, what a pain to take apart to clean (horrible). Which needed to be done every week. I don't have time for that. So glad I finally decided to go ahead and spend the money on this.

Works as described. I had to modify the output to be 2 inches. Drilled a bigger hole and used a bulkhead fitting.

The pressure filter I was using for my pond wasn’t enough so I picked this up and was quickly impressed. The assembly was easy and within a few days my water was crystal clear. The pads are easy to remove and clean and the bottom outlet is perfect for draining the stink water. I wish I had purchased this sooner.

Other than 3 of the sheets were cut shortThe system works wellThere quality control isn't the best

This Matala for my pond medium size with 10 koi . My pond now Cristal clear , every one enjoy these handsome koi.I love it

This filter was shipped with what is apparently a non-standard bulkhead fitting for the outlet side of the filter box. It is not a standard fitting to allow connecting any available tubing or PVC fittings. I went to to 3 hardware stores and a specialty pond supply store to find the fittings to complete the outflow and was told that no available tubing or PVC parts would fit the existing connection (bulkhead outflow fitting). Still trying to figure out how to get this filter set up so I can use it, the return window has passed. The reps at the pond store told me that this was likely a metric fitting and not standard USA measurement.

okay but not so happy! the idea is good but need to improve to an excellent pond filtering box, have problem with the inlet water splash into filters and since cover (top) doesn't have a gasket it drips. and it's easy to overflood since outlet is too small ...

Better than the ones I've used before.
