i came home today to find out the the power switch to tank had melted and fused last night at 12.20 am the one plug controls all my filter , heater and lights. so there has been no filter on for about 17 hours and no lights and temp dropped to about 21.how will this affect my bacteria in filter and fish and inverts. no very much stock so that one good thing. what was working though was my skimmer and power heads and there is 25kg of live rock in there. i have since re wired so all on individual circuits and all back on now.
