Say you saw the flo pipes in his section and the price is in USD, how much to the UK?
He should say £22.50 including shipping, which is a bargain compared to CAL and ADA.
The outflow is cut the same angle as ADA ( like this \ longer at the bottom) whereas the CAL is the reverse (like this / longer at the top)
Don't know what the difference is but if the ADA is cut the same way that it can't be wrong.
The inflow has the ball on the end which has a slice cut through the end about 1.5mm wide and also 2 holes just above the ball.
Some people have said they don't like the ball bit on the end, but I think it looks quite cool, and at the end of the day, you don't really see it in a planted tank.
I will take some pics of mine later if my crap camera can see them, if not you'll have to wait until my new camera arrives next week.
