2 Ultra quick Questions - Honest!

[RogerandRandy]

'Evening all... Could somebody clarify something please:

Feeding our new li'l turtles, we have read in various places to feed them once every 2-3 days with enough protein to fill their heads once over. Also we have read to give them as many leafy greens (watercress in our case, currently) as they fancy. Is this "Green Buffet" every day, or just on their feeding days?

And... Even quicker...

I'm looking to get some isolating taps for our Eheim Classic 2215. Is it the 9mm, 12mm or 16mm that I need... The tubes appear to be sort of, around 9mm(ish) but I wanted to make sure the 9mm referred to the actual tube, rather than the size of the taps.

Muchas Gracias, as ever.

Quick answer to number two.
Cut a little bit of pipe off and take it with you.
Another quick one for number two.............have a look on the pipe for any sizes printed on them.

Haven't got a quickie for number one.................
