Hi everyone, new to this forum so sorry if this seems a stupid question! Is it a forbidden thing to use water from hot tap when doing a water change? Did a 50% water change on my 220 ltd tank today, when I refill it I normally fill a large bucket next to the tank and syphon it into the tank slowly, rather than just putting cold in I normally warm it a little to bring it close to tank temperature, done this many times before with no proplems, today after doing a water check found a raise in ammonia level, after a lot of head scratching did a test on the tap water..... Cold tap was fine with neutral levels when I tested the hot tap it was more than 8ppm! Sorted it now with another water change but has anyone else experienced this?
