pond cycle?

[Priscilla]

I use powerful large sedge for photosynthesis filtration. My favorite sedge is my very large yellow flag water iris. It is not potted in anything, but it naturally floats in my middle pond as the roots are buoyant. If you can get a clump from a large sedge to grow, like a iris, cattail, grass, (any water plant with a spear shaped leaf) then your pond will stay much cleaner!

Do you have a picture of your yellow iris floating in the pond? I would like to see that.

so i will ask the controversial question - as i am fighting the bloom too...
thought we had it under control after adding some of the barley concentrate - but its back i think.
Should i start my UV light?
Will it indiscriminately kill my good bacteria too? <- controversial....

Let's see...barley clearing a pond is a myth and a properly sized and maintained UV is 100% effective in clearing a pond in 5-7 days. So yeah, turning on the UV would be good choice.
