raised pond filter and live plant area need help

[scott70]

Hi all my next step in building my new pond is to build a 10 by 12 by 3 foot deep plant pond to help filter my main pond I will also have 3 external filters also all will hold 150 gallons each but what I need help on is how to build the box it will be on cement so I dont need a bottom but I want to make the sides out of wood I was thinking 2by4 on 12 inch centers and 3/4 ply wood for the side walls also bolt the box to the cement with some center bracing but not sure that is a lot of water to hold back the hole filter system will hold 3450 gallons when done my new pond will be around 10000 gallons so plenty of room for my koi thank you all for your help

I thing you will be fine, just make sure to really anchor your 2x4, you may want to use 4x4 and make sure you use pressure treated wood. In each corner, brace them well, corner brace, well screwed in. Use some of the bracing they use for building decks etc.

i would drill matching holes thru the 4 x 4s and drive either rebar or metal conduit thru the walls atleast 2.5 feet into the ground...conduit wont rust out below ground....drill the holes so its a snug fit.
