Sand Sifting Star Q

[marknash]

We've been having an on going problem with red slime algae. we've changed everything in our tank.. got new bulbs, increased flow, decreased feeding.. increased water changes and we are still getting slime everywhere. was wondering about a sand sifting star.. we currently have two koralia 3 .. in our 46 g bow front the tank is only about 4 months old. do you think a star would help?
any other suggestions would be appreciated..
