I have had my hands in pond water for thirty years now; our first pond was 450 gallons and when we moved we put in a 2000 gallon 5X17 ft pond (size due to limited yard space). I have a Ultima II bead filter with a sequence pump and priming pot which I installed myself 10 years ago. It works great. Two or three years ago we installed a bog filter with a waterfall and many plants. My husband and I made the filter box out of concrete and if anyone wants to know how not to do a bog filter we can certainly help! It works great now is all I can say about that. In addition we have a small submerged filter box with a 1200 gph pump that goes to the UV light. We have six very large koi and three babies from last year (yech, spawning with big fish makes a big mess!) In the past we have split the intake to the bog filter so that half of the suction goes to a freestanding Oase skimmer. The skimmer is great for removing surface stuff, but inevitably something would cause the skimmer to float up causing the pump to cavitate disturbing the bog filter as well. We removed the skimmer over the winter but it was quickly evident that it did a good job so we bought another pump to run the skimmer routing the water through a Tetra Bio-active pressure filter.In the description it states that 1 1/2" ID hose is needed and based on that we ordered 50 feet of hose and a pump that would accommodate 1 1/2" hose. Now I am ready to do the hook up and I see that the threaded outlets are 1 1/4" not 1 1/2". If I had known that I would have gladly used 1 1/4" hose but it clearly states in the literature and on the filter itself that 1 1/2" hose should be used. In addition, the female connectors that attach to the threaded outlet have a barb that accommodates a 1 1/4" hose not a 1 1/2" hose. I found adapters that will take the 1 1/4" thread to a 1 1/2" barb but they do not screw on to the 1 1/4" outlet. The threads appear to be the same width but the tetra threads are quite rough. When I called Tetra they said that they would bring it up with the engineers (big help to me!). I was also told that no one else had called to report difficulties; that's also extremely helpful! In addition to that, the basic design of the connectors is flawed: at some point the lid to the filter will have to be removed which will mean that the hoses will have to be disconnected. If the screw on connector is not a swivel the hose will be extremely difficult to remove from the barb. I guess no one thought of that during the design phase.
One way to make this work is to use 1 1/4" hose but the instructions clearly state that 1/12" hose be used and I will be stuck with the cost of the hose I have as well as purchasing 50 more feet of hose.
Has anyone had this issue with this filter?
Sorry this is so long but wanted to provide as much info as possible.
