If none of the above resolves your issue, or you require spare parts for your 

filter, please contact the supplier of your unit.

SPECIFICATIONS

My Pond Water is Cloudy/Brown

1. 

Make sure the unit is turned on 24 hours a day. Continuous running is 

needed to maintain a clean and healthy pond.

2. 

Remove pond waste and leaves and carry out a partial water change. If 

sludge is present treat your pond with All Pond Solutions Anti Sludge 

treatment.

3. 

Reduce feeding. Overfeeding introduces a lot of organic waste and is one of 

the main causes for cloudy water problems.

4. 

Make sure to perform regular water changes, check your unit is clean and 

adequate for your pond size and do not overstock it.

Blanketweed attaches itself to the walls, plant and 

rocks within your pond and is sometimes known to 

float on the water’s surface, this can prevent to 

blanketweed from being pulled through the filter 

and UV resulting in the algae not being treated.

In order to treat blanketweed use All Pond 

Solutions Blanketweed treatment. This will bind to 

the blanketweed and break it down. It will then 

allow the filter to pull the remaining algae through the UV system eradicating 

any spore the blanketweed may release, and finally filter it out.

My Pond Water is Cloudy/Brown

Will my CUV unit remove blanketweed?
