I have golden mystery snails and they do a number on algae.
Other ways to reduce algae....
Less lighting. I ran my light for 10-12 hours a day and got a lot of algae build up.
Boost co2. This goes hand and hand with reducing light. Co2 will kill algae off quickly but can kill your fish if you use too much at once
Over feeding. Most common way. If you reduce feeding, the algae won't compete with your fish or live plants for nutrients and should die off.
Those are the 3 tips I was given in the past. I used too much lighting. I reduced it and now my algae is under control
