afternoon everybody...... just so you know... dont forget you only need to put your siphon hose in the top of your tank rather than doing a complete vacuum of the bottom every time you change your water. try filling 2 buckets at a time... it should only take 5 minutes to do a part water change... also if you do vacuum your tank you might want to take the large tube off the end of the hose and simply use the hose...... better suction.*twirlysmi
