MY pond water is green. I used microb lift for weeks every week and almost killed my lotus. The pads started turning brown , I don't want to use dangerous chemicals to hurt my fish and plants but what can I use to get nice water like other ponds I see. I tried barley pads last year, but didn't seem to be doing anything either. Just went to the bottom of the pond where I have a mess now.BUT made rich place for growing water lilies.However I still have green water. Can't see my fish unless they come to the top of the water to eat. I barely put food in for them to eat so can't be that. What am I doing wrong?
