| I gave the media one extra flush, but I could have got away without.
When flushing, I drop the water level in the filter to below the slots in the pipe and then turn on the air. The air then runs continually untill the flushing process has finished. Each time I refill the filter for flushing, I keep the water level below the slots, this stops any waste passing on into the transfer pipe.
When the air is first turned on, the water takes on a pale tea colour as the fines are mixed into the water, with each flush the water becomes clearer, when filled back up after the final flush, the water is cyrstal clear. The air is turned off before the final fill up.
At times some blanket weed has needed to be removed from the drain outlet grid, this is the odd occaision I have had to get my hands wet.
Blanket weed could be a problem, as Kaldnes is not a smooth media, because of this I have often wondered about getting some bubblebead media, as the round beads would stop the weed from 'hanging' on. Though it's never proved a problem for me.
