well we dont have a maid and we havent cleaned the glass with any cleaning products and as for air freshener we have a air purifier / freshener thing that swirls and u add the scents too which sits like next to the tank .. but if it wer that wouldnt a water change fix the problem tho... so im completely clueless as to wat this can be . every frag of a coral i stick in lasts a day then by the next day its shriveled up and basicly dead.
