The outside temp has been fluctuating alot lately (much cooler at night). I recently readjusted a huge industrial fan to cool the lighting and water, but I hadn't bought a timer for it. Last night I accidently left it on all night and my temps dipped to 74 and my tank evaped so much that the salinity raised to 1.028 (from 1.023).
what to do?
