Dear Fellow Koi Lovers,
Re: [chlou] Vortex Units - Urgent!
[In reply to]
It's been quite a while since I last joined the forum. Very impressed to see the change in look of the website. Great work and congratulations to our Webmaster.
My pond with the vortex system worked very well untill 3 months ago when the water suddenly turn green and became worse after I gave the filter a good flush (to remove those annoying water snails). The water has not turned pea-soup but occasionally green enough to have a visibility of only 1-2 feet depth. The green water problem seems to worsen during the rainy season.
Tried partial water change, added "Cycle", Biozymes...Nothing seems to be able to turn the situation around. Water is slightly alkaline, no ammonia, no nitrites and 12.5 NO3 and repeated tests showed same results. Refused to use algicide and still hoping for a natural turnaround.
Dear friends, what have gone wrong?
