Hi, this morning when I came downstairs to look at my 100gl. tank the heater wasn't on and the lights were off. The heater is on now and so is one light but the other on the same outlet won't and I think I need a new bulb. The temp was 71*f. I only keep it at about 74*f. and there is alot of alge the back panale is coverd in it. Its green. Will a snail fix the algea? The fish that I have are zebra danios and guppies and glo fish and hope fully soon a new snail.
