hi I’m a new pond owner in south FL I have a 650 gallon pond I just started with a 1200gph biofilter fountain. It’s only 4 weeks old and I jumped the gun and put 10 small gold fish it in it. That’s when the water turned dark green and the top water has a lot of white bubbles from the fountain. I’ve herd of new pond syndrome but my fish are not showing signs off illness so far and it’s been over a week so far. I’m not sure what to do now? I used a blue tint dye in the beginning bc I was told it would help with algae but I think i made it worse... help!
