The above is a link to the plans we used to build the sand & gravel filter. I say "we", but my husband deserves the credit!

I'm posting some pictures I took this afternoon. I'm still mulling over ideas for the appearance of the wooden structure my husband built to hide the barrel and camouflage the three inch return line.

The first time we back washed it, we used our shop vac. The second time, it didn't work and we discovered it wasn't strong enough. Ironically we had great success using our professional dog blower ( we have three newfoundlands ) and it's truly amazing to see the gunk that comes out.

I'm not a serious koi keeper, but am serious about taking good care of them :) A down side to this filter is, if you don't like to perform water changes, as you need to add water after back washing it. My hope is this filter reduces the time we spent cleaning our old filters.

According to the directions, it can be cleaned every two weeks, but I'm cleaning it a couple time a week for Spring start up. I think I'll clean it once a week during the summer.

How long did it take to build it?
Well, longer then it should have - ha ha! I originally thought it would be on cement blocks, painted and landscaping around it, but hubby built this structure, which took time.

The actual filter didn't take that long, but we had to redo plumbing etc. Trying to decide if I'll stain the wood, or paint in the same shade of green as the pond shack...as we call it :)

I would encourage those who are interested, to try it. The man who created the plans is super nice and answered our many questions.

How many pumps do you have running? Just the one going to the new filter?

2000 GPH is recommended for the filter, so the media doesn't fluidize. I have a 2000 in the skimmer. I also run a 3000 GPH pump to the water fall.

Trying to think of a use for my 1200 GPH Pondmaster, but have it pulled for now.....maybe I just don't need it.

My goal was to simplify pond keeping , while improving filtration....and hopefully not ruin the beauty of the pond area!

I forgot to mention we bought the kit from the guy who designed this. It cost $149 and it had all the fittings included and came pre-drilled....to us, it was well worth it. I bought the barrel for $30 off Craigslist. We had to buy PVC pipes and the media, both from Lowes....except the chicken grit...that came from Tractor Supply.

How often does it need to be cleaned?
I've read varying suggestions. I think a good measure of when it needs cleaning, is to remove the cap from the pipe the blower goes in and if the water in it, is high, or flowing over the top....it needs cleaning.

Right now I'm cleaning it a couple times a week, hoping to stretch to once a week and longer, during the summer. It only takes a few minutes to back wash it and another 15 minutes to replenish water to the pond.

Like the hide! If it was mine I would paint it green like the other blends in more.

Great job on the S/G filter build.
Does the skimmer that houses the pump feeding the S/G filter have mechanical filter pads before the pump? I ask because if the pump is prefiltered for large particles less will get to the S/G filter . Then maybe it would take longer before needing to be cleaned out.

The pump sits inside a Savio skimmer and just has the Savio pads, which I rinse regularly. I've read where some serious koi keepers have sieves and such, before the S & G filter, but the man who designed this filter, told me, it's all I need due to the size of my pond and only having 4 koi. I sure hope so !

That's what I'm leaning towards :)

Hubby originally wanted to make a door and roof for this structure. I'm not so sure.....I think if it's painted green, it'll blend with the hedge of box woods behind it and the barrel has a lid to keep debris out. I kind of like having it open in the back and could paint the barrel green too...just not sure yet....if he wants to build a door, that would be fine too.

Thank you for sharing your S/G filter!

My waterfalls don't have a back-flush, so I only clean those once a year during Spring cleaning. I rinse my mechanical filter pad every couple of days, and that's all that I do to maintain the filters in my pond. The water parameters (when I do check) are always good, the fish are active and healthy, does it mean I'm ok as far as filtration goes?

Sounds like minimal maintenance and good results :)

@Tula , I saw you post on kiophen in Oct or Nov about running the S/G filter thru the winter. Did you keep it running? IF you kept it running how did it go? My climate is similar to yours. I plan on building one this spring.
