I am new to site but have my first pond. Currently it is only 90 gallons with a 330 gph pump inside a stock filter casing I got from home depot. I am going to rebuild the pond into 200+ gallon pond with a pond liner instead of the prefab lining. Is it worth building a tank filter for this size, and would I be able to conceal it? Plan would be to build it in back and have it built into the waterfall. Would my little 330 GPH pump still be enough? I realize i would be making a small 20-30 gallon filter for this. Pond is currently very cloudy and out of sync, but I have 2 small koi and 6 goldfish in there. here are the pics

To clarify talking about the DIY Doc bio filters. I spent about 6 hours reading posts on here today and didn't see many small ponds. Bunch of hard core pond owners in here :)

They grow on you!

The pump you have will turn over a pond of 200 or so gallons every hour. So the pump is fine. A diy filter will help keep the pond in great shape, conceal it with rocks, wood etc. I would make the filter as large as you can, it will help you balance out your pond.

And your little pond looks great btw

I might consider upsizing a little, once you cut the hole for your overflow, it won't hold 70 qts anymore, but the idea should work out well. And who am I to say? Anything will work, if it is not enough, just build a bigger one, right?

Ya, I saw his post and was thinking of a more durable plastic. I have one of those 70 qt feed buckets i may try and convert. How important would the height be? this is similar to what I have on hand.

those are all around. but I am thinking something taller would work better. got a rubbermaid fliptop garbage can today for 16.00 like two 5 gal buckets tall. I want one with a bigger bottom drain and I will glue the fittings in.

I have a few of those laying around, nice and durable, survived arizona sun for around 5 years.. Like they say if it is not big enough you could make it bigger.
