I definitely agree, Mark.
One relative newbie I met at Gardena told me they're feeding twice a day. Not only can that trash water quality, but a lot of the energy from feeding that heavily at this time of the year will be going towards egg production.
We're still feeding wheat germ once a week and have been since Jan 1 -- even though our water temps have been up and down in the 54-61 degree range that entire time.
Starting April 1 we'll increase the frequency; later we'll increase the amount; and not 'till June will we start mixing in a higher protein feed.
I guess that puts us way out on the conservative end?
