Waycreat2-Way Aquarium Air Flow Control Lever Valve Distributor Accessories Set with Check Valve, T & Straight Connector and Suction Cups

This item doesn't work. It allows you to connect 2 to the splitter, but can only flow the air to 1 or the other. Not both simultaneously with the regular air flow. If you manage to get air to both, they are significantly weaken. Even if you use their T connector to combine the air into 1, it still too weak. Results were much better without this item. I'll probably just use this junk as a on and off valve and not the splitter/valve as it was designed for.

Both check valves failed completely and damaged my equipment.I run a CO2 system on a planted tank which turns off at night. When the CO2 turns off, an air pump turns on overnight. The check valve on the CO2 line failed and water backed up into the solenoid, killing my $150 valve. During the day, when the air pump wasn't running, THAT check valve failed and my new air pump filled with water. Avoid this garbage at all cost!

I would say the suction works well. I have shown the same picture as with the filter I also just purchased. Poor little sponge filter even has a heavy weight on the bottom. The corner filter won't let me adjust it, so for now it is just cleaning debris in new tank

Comes in handy you will use most of it, just be careful on the tube u pick because they one i had did not fit Although I did not try hard It might would have fit bt i didn't have the time to make it fit i use another??? Well whatever the silver splitter is called, bt the check valve i made fit on the tube with a little pushing.

Valves are worth the price of the assortment. On/Off only like all metal valves I've used but off is off and on is on. No micro bubbles when in the off position. The connectors and suction cups work well. Will be ordering a few more as Multi Tank Syndrone gets a deeper grip on me.

These valves are sturdy and the control-throttle handles work very well. I can easily split air flow into two separate tanks with accuracy. Also, the valve workmanship quality is excellent.

The airflow valve can basically just be used as an on/off valve. If you need a valve to finely tune airflow, then look elsewhere.All other parts are your standard plastic pieces you can pickup from nearly any fish store. Quality is similar for those.

The valves were just okay. All the other little bits were decent except the suction cups. They lose suction after about a week.

Super easy to adjust the air flow to different areas in the tank.
