24W is fine, I shoot 27W for my 1.5footer and it has not much problems whatsoever.
Anyway staghorn algae needs to be removed manually first and then you let your fauna pick up the rest. You can find SAE easily at C328 and NA but you might not be solving the root of the issue.
Reconsider your CO2 and fert regime. With 24W you need to ensure that your fert and CO2 and pick up, I dose ALOT of fert and inject quite a bit of CO2.
