one of my tanks were turned completely off all night with no filters or heat, due to a faulty power strip. everything looked completely dead but after a few hours of circulation and heat everything seems back to normal , except the PH is super low. its at about 7.6 or so. no ammonia, nitrates/ites my refractometer says its about .026, which is weird because it was .024 yesterday . i dont want to do anything at all until i get a more informed opinion on what to do so for now im just letting it sit there and recover. so what now? thanks for the help doods....
