My Shopping List... (Please Review)

[Superman]

Right, so I'm going to do some shopping. I would appreciate it if people could review my purchases and where I'm going to get them from - to make sure I'm not buying from people who aren't any good.

New External Filter:
JBL CristalProfi 500 from Chaterhouse Aquatics @ £89.95
http://www.charterhouse-aquatics.co.uk/ ... -1528.html
I have chosen this filter as:
- It fits into the space in my Juwel Vision's cabinet, the width is 24cm with a little bit more space in the length
- provide a good output for a filter of this size
- grey tubing, so it won't stand out in the tank
- no bad reviews, but then not really seen many users in the UK

Power Head:
Need this to connect to a garden hose for a water changer system similar to LondonDragon's. Thought I'd get this one as it's from the same company as I'm getting my filter from. Similar ones on ebay including p&p so not losing out.

Dry Ferts:
All from Garden Direct as prefer to get from a single shop (would get from AE but there is a large price differential)
Potassium Phosphate (http://www.gardendirect.co.uk/potassium-phosphate-p-213)
Potassium Nitrate (http://www.gardendirect.co.uk/potassium-nitrate-p-210)
Magnesium sulphate (http://www.gardendirect.co.uk/magnesium-sulphate-p-894)
Trace Mix (http://www.gardendirect.co.uk/chelated- ... -mix-p-887)
500 grams each

Don't think I've missed anything...
