I can understand that ..but I clean mine once a week and it stays fairly clean .Also the air stones help a lot from letting water get stagnant or for anything harmful to build up ... And since I started using H202 they're doing better than ever ..
Side note - since my incident with the H202 it's my new practice to wear gloves lol
I just posted this in the DWC forum.
Basically what mine does.
Also, I change my water every week too brutha man.
That's the beauty of MY design you don't see often. Gravity does all the work. The return lines are all at the bottom of the buckets and return on individual lines to each of 6 holes on the bottom of the reservoir bucket. In the res, there is a pump that comes out with a tube line, through the wall of the top of the bucket and splits. Then the lines are used like a manifold and teed into the top of the bucket wall (same as the res) fiirst two buckets are Tee'd and elbowed(90*) on the last. All connections are just barbed fittings stuck through donutgrommets. The pump from the res uses the water to supply these "waterfalls" and as the buckets are filled and the res is drained, the weight of the extra water in the 6 buckets pushes the extra weight down the return line back to the res.
This sketch is supply line and would be on 9 buckets but it's just the outer rows and a Wye instead of a cross like that to split the lines. This doesn't show any return lines. Those are all the first ones on first post.
But it's super easy to build and you just need 1 decent submersible pump that are cheap. InLines are a bit more coin.
All the buckets have air stones and air lines going to an air pump with a 6 valve manifold too, obviously. But the waterfalls in each help a TON with dissolved oxygen. I think ?
@ttystikkhas some experience with this.
These are the return lines. I have now. And then what I plan on upgrading to. It has both supply(thin lines) AND return (thick lines) on it.
