Thanks esshup! I did not know that about Optimal. I’ll give it a few weeks and post a report on how things are going. Heppy
A few years ago I was called to help a fish farmer deal with a low O2 event in his 35 ac lake where he grew HSB in cages. IIRC he did a feed test the previous few months with the HSB and I think he was trying 5 different mfg. of fish food, including Optimal. All the cages had 90+% mortality in them - we are talking cages that are 8' wide, 8' deep and 20' long, HSB were in the 1#-1.5# range and the surface of most of the cages were a solid mass of dead fish. Not a pretty sight especially after 2-3 days, you made sure that you were on the upwind side of the cage when you were scooping out the dead fish.
EXCEPT for the cages that he had fed the Optimal Fish Food. Only 10% mortality at the most..... I knew that the Optimal food was good because I had started using it in my pond and saw a reduction in the amount of FA in the pond but that really opened my eyes to just how good it was. The thing that really got me was that he had stopped the feed test more than 30 days prior and those fish STILL survived.
