That means that you have very little of the phytoplankton. Phyto, mictoscopic plants, is the basis of the food chain. They are fed on by zoo plankton, microscopic animals. The zoo is eaten by tiny bugs which are eaten by larger bugs and small fish fry. Things like that keep happening up the food chain until you fillet a bigun.

Without phyto you have an essentially sterile pond where fry have a tough time surviving.

The clear water is what allows the weeds to proliferate.

AFTER you get the salad under control, you may need to look into fertilizing.

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.

Boy, if I say "sic em", you'd better look for something to bite. Sam Shelley Rancher and Farmer Muleshoe Texas 1892-1985 RIP Grandpa
