PWC Grand Prix

I decided to have a little fun with my second water change last night and time it. I didn't go as fast As I could because the kids were asleep, but I definitely pushed it to the limit.

Step 1: Siphon out 9 gallons of water.

• Bucket 1 - 2:49.05 minutes
• Bucket 2 - 3:00.00 minutes
• Bucket 3 - 3:20.04 minutes

Total: 9:09.09 minutes.

Step 2: Put 9 gallons of pre-treated water into tank. Total: 2:38.80 minutes.

Step 3: Refill 10 gallon cooler with 9 gallons of tap water.

• Bucket 1 - 1:35.90 minutes
• Bucket 2 - 1:06.90 minutes
• Bucket 3 - 1:03.00 minutes

Total: 3:45.80 minutes

Step 4: Treat tap water with water conditioner, aquarium salt, and pH 7.0. Total: 00:56.60 minutes.

This makes the grand total for a 50% water change: 16:31.90 minutes.

Siphoning the water out of the fish tank took longer the less water there was in the tank, which I'm sure there is a scientific answer for.
