Hi All,

I usually purge my B drain and discharge my settlement chamber weekly - then top up from the hose (using cleanser)

My pond is only 750 gals, and is currently crystal clear and the water tests are on the numbers. Only use a homemade standpipe chamber, and running it though a box filter.

...so was thinking once a month may be ok throughout the next few months? Is that advisable?


Many thanks!
