and my tank is still in the process of cycling. At the moment Im doing water changes daily - or every second day coz ammonia keeps spiking. I have friends who are looking after the house, but have absolutely no idea about the cycling process, changing water etc etc.. What should I do? Should I get some ammo lock just incase? I know that most ppl dont like to use it, but will it help in this situation? I am going to get them to replace some of the water every second day, and leave detailed instructions, but they'd have no idea how to use a siphon and do it properly. So am a bit worried! Chose the right time to go away! geez!
