I've started to do WC twice a week at approx. 35% each change. I also change the filter floss at this time as well. Between water changes I would only fed them twice max 3 times of only a bag of shrimp so no over feeding. Water Parm's are good, water cystal clear, sump's all good, temp's mid 80's, lots of water movement!...but...
why am I seeing white film in my tanks sometimes covering my rays tail and their eyes? yesterday again one of my BD's eyes was completely covered white!....and had some white slime or film on their tails....so I did my water change....and this morning they were gone!? what the heck are those? driving me nuts......added salt on the changes as well to see if this will eliminate them...
Any thoughts?

I'll try and get some photos next time it happens....
 
salt should help. i had the same thing on my bichirs. what i did was reduce market shrimp feedings and added salt. It usually go away then come back when I feed too much market shrimps.
