Is this a good idea for a prefilter?
This is my setup. An above ground 3000 gallon pond with a bottom drain and
Oase 200 skimmer feeding a Sequence 3800 pump. Then the water is being pumped into two one hundred gallon skippy filters back into the pond. The problem is the p-trap keeps getting clogged I have to unscrew and clean twice a day. There is stuff that gets though the skimmer and sucked through the bottom drain into the ptrap basket and clogs it. The daily cleaning doesn't bother me but makes it almost impossible to go on vacation. I am thinknig of putting two bulkhead adapters into the side of the pond one for the skimmer and one for the bottom drain. Then running these lines into a 55 gallon drum towards the top. Keeping the water line a few inches below the top of the drum. Then hanging a 5 foot long mesh bag over each line so the bags will catch anything that comes in. The bags can be purchased down to a micron of my choice I think around 40 would be good maybe smaller if they don't clog to fast. Then plumbing a two inch line to the ptrap of the pump. With bags this size I think I would not have to worry about the bags clogging and I think they would provide adequate flow. Not to mention they are easy to clean. I could have a couple of spares on hand and change them and clean the dirty ones as needed. Does anyone see a prblem with this idea? |

Chris, this sounds like a reasonable solution. Our pond doesn't have a
bottom drain. Our pump (a Little Giant sump pump) sits in a basket of lava rock, and grinds up small debris that makes it way through the "prefilter" of rock. In the spring and fall I have hung mesh bags (with various sizes of openings) to catch this debris. I've also used the nylon socks that you can sometimes find at hardware stores that are used over slotted drainage pipes to prevent sand or dirt from filling them. I just knotted one end and secured the sock to the pump outlet in the first barrel of our filtering system. It's great for catching small debris and algae in the spring. Let us know how your new system works. -- Kathy B, zookeeper 3500gal pond (Oregon) |

Ponding is not exactly rocket science. Why do you have a P-trap in the setup? On Thu, 29 May 2003 19:51:18 -0500, "Chris" wrote: This is my setup.

I want to make sure nothing big gets sucked into the pump. I did this
originally to catch the big stuff so it would not get sucked into the pond. The problem is it has to be cleaned to often. I want a big prefilter and would not even need the ptrap at that point.

I want a big prefilter and would not even need the ptrap at that point. Yep. I retrofitted a settling tank (a 32gal plastic trashcan) to my filter, loosely stuffed with bird netting. ALL the visible stuff is caught and I clean it once a year. The bird netting acts to slow the water flow so the particles drop out. The mesh is so large (3/4 inch) that it just never clogs :-) The next stage is a biofilter with plastic gutter screening and then the pump, through the UV and back to the pond. Once a year maintenance. |
