Hey thanks a lot. I've been following your grow out thread as well - very inspirational!
I actually do wc's in the evenings shortly after the BH feeding so they can be in clean water all night. I then feed the fdbw in the AM as it seems to be the least messy, followed by discus chow in the afternoons. That's why I was thinking my only option was to cut out the discus chow in afternoons - although they do go crazy for it.
