 Re: My Pond
Thanks for the comments. My trickle tower is made of three stacker box`s from B&Q.
I have fitted a 40mm spray bar at the top via a 40mm tank connector. Then drilled loads of 10mm holes in the bottom of the top two tiers. The last box I have just cut a long grove along the bottom, were the water returns to My pond. It makes a good steady splash so plenty of free air added as well. The trickle tower is has two box`s of Bacteria House Media shared among the three tiers. That was the expensive part costing Me £280, but well worth it as this stuff is the Mutts Nuts.
