Aquarium gravel cleaner vacuum siphon head

Aquarium gravel cleaner

for cleaning the gravel or substrate in the bottom of your tank.

• Makes cleaning really easy!
• Avoid stirring up the substrate and getting dirt up in the tank water.

This is available in four sizes to fit different hose diameters - it fits around the outside of the hose to maximise flow rate. Choose the plate with the size you need, or scale one if your hose isn't listed (it's the outside diameter of the hose you are matching, not the inside diameter)

Printing

This is an easy print - single part, no supports, no AMS.

Print this in transparent PLA or PETG in order to see the gravel rise up inside the tube. Even though ‘transparent’ filaments print more as just transluscent, when under water they do work well to let you see the gravel within the chamber.

Usage

Connect your hose to the top of this device. It's a push-fit, no need for glue.

Submerge and pull a siphon so the water flows through the hose and into a bucket. Control the speed of flow by blocking/opening the end of the hose in the bucket with your finger.

Push the device into your gravel in the tank, and allow the water to flow. This will raise the gravel up in the chamber, and the dirt should flow out into the bucket. If the gravel looks like going too, restrict the flow with your finger, and gravity will let the gravel drop back down.

The device has a filter grid at the top to prevent large gravel going through, but small bits of gravel or sand will pass through it you don't control it.

Keep an eye on the water level in your bucket - it's easy to focus on the tank and not realise the bucket is overflowing!
