FoxFace or Kole Tang for algae

[scuba guy ron]

I'm having an issue with Udotea algae and have been for over a year. It's a green algae that is partly driven by calcium so it is VERY difficult to overcome. I'm going to try a controller and have narrowed it down to these 2. Which would you think I may have better luck with eating this?

Everytime I add a fox into my tank, it gets rid of all the algae and they keep it gone too. The problem is my tank is only a 92 & and that fish gets big and fast!

If your tank is 37g as indicated in your signature, neither will work as they both need bigger tanks than that. A lawmowner blenny will be a good option.
