Yes safe as we are about 400 miles away.bean6924 said:Howard - This seems to be the concept. I'm curious to hear if your "down up flow" filters worked, and if so - how often did you clean the filters?
btw - Hope you're safe. sounds like a tough time for you in oklahoma...
I opened the bottom to back flush it about once a week.
I have it hooked now to my overloaded holding tanks/lift setup while the pond is being redone. The ammonia exiting it is 1/2 PPM lower then the water entering it. So that part works. I do not know that it is fully cycled and there is some ammonia removal via green water (a good thing in this case). It has a rio 2500 which should be flowing about 530 gph which is low but seems to work.
Crap come out when it is back flushed.
Thinking it would do ok on a 1000 or 1500 gallon pond with normal stocking levels.
Guess it works
There are so many variables.
I had used it on our 'for sale' pond. The pond was small but we were moving lilies in and out of it frequently and a lot of dirt got dumped into the system. Generally it would clear the water in about a day but then it was not very deep or big. The pump was small so it was not near max capacity flow wise.
