Ok so yesterday i had to lower my tank water level it do some stuff and left it low all night until now. I'm about to refill the tank and want to make sure that i don't harm anything. I have also had my light off for a good 26+ hours is it ok to just turn it on??? And when adding the new water i need to 1st make sure salinity is the same then the temps are close to the same right?? Is there anything else i should do?? so that i don't harm the fish and few coral i have left??
