this is wat i did for the last 3 days when plenty can be seen near my filter.
- spray water directly at them and destroy 50% of their population around late evening 3 days in a row.
- wash the filter thoroughly and change 20% of water (to remove debris, increase water flow and reduce still water).
- put in pandan leaves at the side of the empty space of the filter (was told the smell will drive them away)
- reduce feeding for a day or 2.
- put in a few of my guppies in the filter in case there are still lava in there.
no sure if this is the rite thing to do but the whole pond is now clear of midges and mozzies.
conclusion: i think its the water quality and pandan leaves.
