      Anyone running Profidrum Shower?

      I have a combi bio 30 and recently added a shower with BHMedia. I could not find anyone one the internet with one. Pics and opinions would be great.

      I never knew they offered a shower filter. Any chance of more pictures of inside the unit itself? What's the flow rate?
      Is it sealed? How much media does it hold?

      Yeah I didn't know they offered one, either. How does the water return to the pond, through large OD pipe connections?

      Bet those two pumps suck a lot of air!

      holds 40kg of bacteria house media. flow rate is 6000gph. Im running a sequence 5800gph pimp. It has three tiers. Each tier is double stacked with media in a cross hatch pattern. there are better showers out there but not one that sits on top of the combi. Its a closed loop. I have 150liters of K1 underneath. Can barely hear the shower with lid on.

      No at all despite running a return pump of 8200gph Sequence

      I"m confused... how does water get to the top of the column... a pump, right? The water flows down through the bio, but how does it get back to the pond. The one picture above appears to show pumps at the outlet of the shower filter, but it's hard to see where the outlet pipes go. The reason for the questions is that if you have one pump pushing water to a filter, and another pump pulling water out the other side, and there's an air break between the two, they'll never flow the exact same amount of water. Either the water level under the shower filter will slowly rise and overflow, or it'll eventually get lower and lower until the second pump is sucking air. I'm assuming there's plumbing that's not visible that shows it's a different arrangement.

      I think a pump is dedicated to the shower. Combi moving bed to shower return to Combi moving bed. Saves space wastes electricity.

      I'm still skeptical a very small depth container with a aerated moving bed along with a tall shower mounted on top can have a pump sucking from the bottom with zero air in the intake. Air in the suction line hurts pump performance.

      The shower is closed loop. no micro bubbles in pond since Dec 2020 start up despite maxing out flow rate of 8000gph. wasting electricity is relative. Most ponds run more than one pump for many reasons. Ill take video this afternoon. thanks

      Looks interesting. What is the cost of the full combination?
      Also who sells it?

      I purchased from Torri Farms but Koi Acres is another retailer in the US. The shower I had to get from Absolute Koi in UK.

      Looks to me like it is a gravity flow into the RDF then moving bed chamber. There are 2 pumps one that goes to the top of the shower which basically just recirculates the water in the moving bed section and another pump that supplies the pond. The water from the first pump is coming from the filter and then going directly back into the filter so no extra water is being added so balance shouldn't be an issue. If either of the pumps goes bad either the shower will stop working or no water gets circulated back to the pond.

      Unless you just need the extra bio capacity I would think the moving bed alone would be plenty and not stick up above the pond. Plus the added expense of running a second pump which defeats the low head advantage of a combibio unit.
