Ok yea and no.
1. The oils in the impellers are hard to remove and any oils leftover will mess your grow up.
2. You can get a sump pump that is sealed bearing or cartridge type, they have no oil or grease in them.
3. Cleaning, good ol dish soap, circulating that for an hour or so, back and forth.
Dump solution and run clean water, 3-4 rinse cycles , approx 1hr.
Dump and fill will water and peroxide, run for an hour.
Dump and rinse with water after.
Fill and ready your system as normal.
But it’s better to get a proper pump and in a pinch a sump pump maybe used but bro, if u see a oil slick chances are your grow will be messed up.
