Garage rack update: fry and breeders

this is my breeding rack in the garage, for tetras, rasboras and barbs. It is a four feet rack with custom plexiglass tanks of 5 gallons. 2 shelves has a total of 10 tanks used to hold and separate breeders which are connected to a diy garbage bin sump. the third shelf has five 5 gallon tanks for fry. Those tanks are not connected to the sump since I use tap water for fry and RO water for the breeders.
