get 2 buckets, fill one up with water from the pond, and one with
water
from the filter return...
compare the water (glass jam jar is brill for this) if both look the
same,
the filter is not filtering..
I would not use this as a method for UV effectiveness, it doesnąt
change the color, it effects their DNA.
i was using it to prove FILTERS effectiveness.. the UV is a seperate
entity, however a lot of people buy a filter with uv plug it all in and off
it goes, as the water enering the filter is "sterile" there is little
chance for the filter to "stock good bacteria".
as to the UV.. it will clear it, just takeing longer... and like ive said
if its Blanket weed, the UV will NOT do anything...
then id recommend turning the UV off and
allow the filter to fill with the "good" bacteria that breaks down
waste...
(a month of running without the uv should sort this) and start clearing
the
water..
If there is a nitrate problem, that is another thing. I doubt it
though with no fish. The food source for the suspended algae is
probably phosphates, cultured bacteria will not effect these levels.
Floating plants; WH and lettuce are the best for this. A recent study
from Thailand said that the lettuce were in fact the most efficient at
waste removal.
This pond just doesnąt have enough UV.
TMC of the UK have made for years and years the very best UVs.
