Hi. Wondering if anyone knows of an easier way to do water changes other than dumping 5 gallon jugs into the tank. My tank is only 29 gallons so I change out 5 gallons once a month. I've heard of automatic water changes but that doesn't seem realistic for a tank my size. I also read about a python syphon but that's not helpful either i think that's only for Fresh water tanks because it talks about putting water back in from the tap. any ideas?
