Got a pic of the algae you're facing? If your tank is still cycling it might be diatom. Running some phosphate removal like Rowaphos can help. My tank is pretty new and because i ran rowaphos at the start, the diatom bloom wasn't very crazy. But at the slightest hint of diatom, i went to buy some nassarius snails to sift the sand and turbo snails which cleared them up pretty quickly. Sand dollar is also a good choice for sifting the sand. As for the glass, turbo snails can climb and graze as well but they will leave their snail tracks and won't completely clear the glass. Better to scrub off yourself. At least you're not facing hair algae like my tank hahaha. All the best!
