Algarde 2 Way Gang Valve

a very handy unit, by just gently twisting twin units apart you can multiply the number of valves to suit our required number, will not rust, can be hidden under gravel/ornaments in tank meaning only one air line down corner of tank, ideal.

I used this in conjunction with a 6" air stone in a tropical aquarium. Whilst it was a bit cheap in quality (I had to make the air holes, it was molded over), it does the job well and overall I am pleased.

You can choose to add 1 or both valves to your air pump to enable you to control the air flow to your tank ornament/air wall.Great little product, very happy with it so far.

Had to drill through to unblock plastic (manufacturing problem it seems). Cheap to buy but you shouldn't have to rectify a manufacturing error to make work!

7/10,ok,had to clear blocked plastic channel[manufacturing defect]with drill,then works.

Rubbish air passages blocked. Needs drilling out before use.

works fine

It does what it says on the pack
