I have a tank with 4-5 small goldfish that has an algae problem what do I do
I tried feeding less and cleaning it but it keeps coming back

That's a lot of goldfish for a 42 gallon. Goldfish really need a minimum of 30 gallons of water per fish, depending on species. The only reason I mention it is that the large bioload of the tank is likely contributing to the growth of algae.
