about 2-3 months ago, I upgraded my 55g tank to a 75g tank. I also changed my live crushed coral substrate to non-live sand. Would the upgrade and the substrate change cause my tank go into another cycle??? The reason I ask is for the past month or so i've been having algae grow right on top of the sand, not on the rocks, just the sand. Also, ever since the upgrade mine ammonia has been sitting at .25ppm. Then I checked it again about 2 weeks ago and it's at .5ppm. SHould I do anything? like a waterchange? or just wait it out?

You more or less started another mini cycle. I would do a couple small water changes over the next week. Things should balance out soon.
