How do I purge theTetraPond Bio-Active Pressure Filter of water in the filter at the end of summer so it does not freeze in winter?

I wish I could answer that but I never turn mine off and only use the clean and pond settings throughout the year. Our weather,is such that even on the few,days where,the,temp gets to freezing it never gets,to the point that the the system is total oy shut down and purging is necessary.

Does not freeze here in Calif., so no need; but just take off the top and drain water out.

I don't know, I left my pond running all winter. I had no problem with it freezing up at all. On my small filter I just took it apart and cleaned it out and put it in garage for winter.

You are doing it right. This is a gravity filter. The water is purified by slowly passing through the black activated charcoal media. It could take up to an hour for all the water to pass through the filter(s). However, sometimes these filters get a little clogged up and slow down significantly. In that case take a sponge with a "soft" scrubber back and gently scrub the filter's surface. Rinse the filter with water and you should see an improved rate of gravity filtering. If your filter(s) have been used for a long while, and don't improve after scrubbing, it may be time to replace them.

I use a very stiff brush and scrub the filter with this brush while holding it under the facet with the water running. To save water you can put water in a large bowl and scrub the filter like that.

My Biofilter is not pressureized When pump is on, which I keep mine on constantly. I use the UV lamp on mine also. Never has it become pressureized.

i do not have that problem. its only for cold water. my problem with this filter is, it don't last the way it used to to about 4 to 6 months.in my case, the last few filters lasted only about 6 to 8 weeks and the flow becomes very slow and restricted inspite of having the samesource of city water.

Sorry, I can't help with this. I returned the item due to poor performance and didn't have it long enough to have to clean the filter. Good luck.

I have not cleaned it yet and use it daily in the winter. I did make sure it was completely empty in the summertime when i stored it. I do use filtered water in it (not tap water). It works fine.

If I may, I'd like to suggest you use "Acurel extreme activated carbon pellets". It's sold here on Amazon and while it costs a little more, it will last you a very long time. I have two of these replaceable filters and they are worth every penny! I got the 45 ounce size and I haven't even used a third of it and it's been almost a year. Check it out and give it a try. They sell it in a smaller size if you want to give it a test run.

Back flushing or cleaning the Trio is easy and is recommend to be done in a clean environment such as a kitchen sink. After dis-assembly, simply run clean water through the top and bottom of the UF hollow fiber membrane. You will most likely see some sediments brake loose from the membrane. After a few minutes of running clean water through the filter shake it dry and place in a solution of vinegar to ensure no cross contamination. The carbon filter isn't the same as pet store filters. It must be replaced with the cartridge from Renovo.

Use hot water; dissolved gases will be expelled and won't bubble when the water freezes.

Bottom tray put bio balls filled with sponge and bio rings with 1 blue fine filter pad, middle try you can put 1 bag of fluval carbon or a better way to go is more bio balls, top try put pre filter rings, if you get micro bubbles turn down the outlet valve until they go away.

If the freezing temperature is only during the night and warms up to above freezing during the day, this method would be OK. The concern is how long the filter will be effective with water running through constantly.

I left mine run all winter in Delaware,as long as the water flows in the filter it won't freeze,however it was so cold this past winter the water started to freeze in the pond and created a dam that prevented the flow of water,so guess what,new filter time. A $300.00 oops. You really don't need to run it in the winter as the fish are in hibernation mode. Just keep the water from freezing solid with a heater or aeriator. Don't recommend buring it as it's too hard to access.

Once every other month or so, when doing a water change in my tank, I fill a five gallon bucket with tank water from the "dirty" tank and rinse/wash the sponges and bio rings and inside of the filter. I refuse the filter and bio ring areas with "dirty" water from the tank. Don't rinse the rings or filter or filter sponges with chlorinated tap water. You will kill all the good stuff. When the rings need to be replaced because they are crumbling, try and only replace 25% or less of the old rings with new rings.

My filter was in use and was not replaced for approximately 18 months. I would say we have moderate water and ice usage.
