i did a water change on my 13" rhoms tank this past thursday, because i was going back to PA for the weekend and this is standard proceedure. anyway...when i got back i smelled what seemed to be rotten garbage!?
after closer inspection i realized it was my rhoms tank, but everything appeared to be fine. she looked great and her four gold apple snail tankmates were all alive. i didnt feed anyone before i left and nothing died. i guess my question is....what made the water smell this bad? i'm puzzled.
i use carbon on my 55g
