frozen vs dry pellet food

[fishytime]

My feeding regiment is made up almost entirely of a mix of different frozen foods enriched with selcon(if it isnt already). I use dry foods only as a "convenience" food if I am hurried to get the tank fed. All dry foods claim to not contain phosphates(but do) and some actually contain copper sulfate(NLS). Just my opinion but I personally dont want to feed my fish a crap load of chemicals and wheat proteins. During the summer I was super busy with work and fed the tank dry foods for three weeks or so. I spent the next few weeks battling diatoms and red slime algae. That was enough for me to hide the dry foods in the back room so I wasnt tempted by convenience and since Ive stopped with the dry foods the pesky algae has gone.
