Can any one help I started up my pond last September I added two small Koi to get the filter started the nitrite was at 0.05 at first then after reseeding the filter it dropped to 0 at the time I was only feeding weatgerm as it was late in the season I stopped feeding mid November when the Temp dropped below 6c the koi over wintered OK I reseeded the filter again in March and have added four more bigger Koi one month after adding the new Koi they all started to flick and flash off the walls of the pond so I added a general all purpose parasite treatment dosed the pond for five days waited ten days and the water was testing OK the fish were still flicking so as suggested on the packaging I repeated the treatment for a further five days the last day of treatment was Friday so I cant add any further treatments until after the ten days are up but when I tested the water yesterday the nitrite had shot up to between 0.5 and 1 so I assume the pond treatment has knocked the filter back I have stopped feeding. Then I cleaned out the vortex and brush camber of the filter as I have done on a monthly basis since the pond was filled when I was cleaning the brushes in a bucket full of pond water I noticed that there were little red worms that to me looked like blood worm any one else had them ? I blasted them off the brushes with the power hose as they would be using up oxygen vital for the bacteria in the filter is there any thing else I can do to speed up the recovery of the nitrite levels ?
