Judy Tipton Bulging eyes Koi I hope you can help Bob. I have 7 Koi (10-20″)+ 3 gold, brought inside 1 month ago from the pond to a 150 gal trough (as I have done x3 years) This eve=Temp 79,Ph6.2 nitrite, nitrate, and ammonia negligible It’s aerated plus filtered with the outside established filter with a high filtration rate 1/3HP pump. I thought I noticed reddish base of 1’s tail base so treated with MelaFix 30 ml.s daily x 8 and I thought improved but after a weekend away one gold was dead and the Koi had eaten most of his 8″ body and now one ?+ Koi’s eyes were bulging -no bloating, scale problem noted, still active. I’ve done a 50% water change added 50 ml.s Melafix and 120 drops aquariology (Zycosin) and Ammo lock 2 just in case! My son says he fed them right all weekend!! but didn’t notice the dead one! Should I do anything else? or just continue with MelaFix/Zycosin? Thank you very much for your
