Just bought and fitted a new product from Reefloat a ATU antisyphon kit. This is ideal for anybody with their ATU pipe outlet above the water level in their reservoir to prevent the reservoir emptying into the sump etc. A simple idea that works great.
The kit consists of a 10mm x 10mm (I think it is) to 4mm/1/4" the tee that simply fits on the line from the pump to the sump or DT if you have it set up that way. A silicon airline from the 4mm/14" tee goes to a small bulkhead on the top of the reservoir if you have a top if not just put it somewhere above the reservoir water level. Simply 5 minute job and very effective.
