Hi. Having trouble lifting 5 gal buckets up to my tank now as it is 5' high to the top. Was using a power head to pump it up but was taking too long as I do a minimum off 35 gallons at a time. Have read on here that you can add the appropriate amount of de-chlorinater proportionate to the water change into the tank directly, then add water via a hosepipe pipe straight into the tank. If the taps are balanced to give a suitable temperature is this method safe? I was worried about any harmful plasticiser leaching from the pipe and into my tank. Any advice would be appreciated. Thanks
