I have another question...........

in my outdoor tub i seem to find some kind of small worms (i guess could be mosquito larve) mostly in the canister filter. Is this a good thing....are there any benefits?

maybe dengue fever ?

once u go outdoor, filter will suck in these active pests. Just need to do regular maintenance. Not much choice.

Oui dengue not endemic in Australia,most of the cases reported are rather imported as dengue is a tropical /subtropical disease.


In any case,the worms are usually larvae of insects(eg gnats)which are endemic in most matured filtration system.No harm of their existence or rather coexistence.
