Co2 Solenoid With Timer

[suvalkietis]

Hi all,
now that I'm restarting my tank and making it proper planted this time, I need a simple not too expensive solenoid for my CO2.
In a weeks time my holiday is over and i'll have to use some automated solution. Two questions:
1. Are there different tube diameters depending on the model of CO2 system? I've got this: http/www.amazon.co.uk/Fluval-Pressurised-CO2-Kit/dp/B005DZ9KZI/ref=sr_1_3?ie=UTF8&qid=1320442490&sr=8-3
2. What and where from should I get?

Thanks a lot for reading and suggestions!

I use one from Lunapet and it's been fine. I believe that most of the tubing is all 4/6mm, although you can in theory get pretty much anything.

How are lunapet with shipping to the UK? I looks like they are Germany based

Fairly fast, but you have to factor the price in. My kit took about a week to arrive.

Arrived today! Just on time! On Saturday?!
A little bit strange how they do ship things tho. After a week of placing my order received email, that it's with their dispatch team now. Was disappointed at first thinking I'll have to wait another week for arrival from Germany, but it took them only 3 days to ship. Very happy. Recommending them for everyone.
