What I’m going to show you today is how to do a gravel siphon on your aquarium. The most important thing first, before you take any water out of your aquarium, is to make sure you turn your heater off, because if the water level goes below the heater, the heater’s got a chance of cracking. The first few things you need to do is get a bucket with a handle just like this, and obviously a gravel cleaner. It’s as simple as putting the gravel cleaner into the aquarium, giving it a shake, then the water starts siphoning out of the aquarium. Then you stick the end of the nozzle into the gravel and it will suck the waste out into this bucket.
This tank has only just been set up, so we’re not going to get a lot of waste out of it, but it shows you the principle on what to do. Now, if you do this regularly, the waste doesn’t build up underneath your gravel, and your aquarium will filter better, and stay a lot cleaner. Okay so you give it a shake as you see here. The water is coming out. The siphon picks up the coral sand, spins it around, and any waste that’s underneath it goes into the bucket here. Move the gravel cleaner around the aquarium to pick up all the waste. To stop the siphon simply take it above the water level.
