First off,

to TFF
I agree with Tetralinz on the test kit and fishless cycling. I have no experience with the Glo range of lights; I either build my own our buy "Silver Sun" units through an ebay member EQJ-trading. They deliver from germany within 3 days at rock bottom prices, and wrap the units in so much packaging that you could throw them off a 100ft cliff and still have a working unit at the bottom... Makes them a pain to get into though

You can pick up units that would cost about £250 in the shops for arround £70
If you use and exturnal filter, get yourself a Hydor in-line heater, they are far more efficient and can keep the temperature even across the whole tank, as they utilise the filter to spread the heat

If you want a conventional internal heater, get a Visitherm, some of these are 30+ years old and still going strong
Filters will bring lots of debate. I run Tetratec on most of my tanks now, and they are cracking filters. Just be careful about seating the impeller cover though, as I have nackered a ceramic shaft by not doing in right. At £15 for the replacement, a mistake like that isn't cheap....Otherwise they are well thought out and solid
Eheim's have the best reputation, but avoid the Ecco range, and their thermo filters. They are both awful, as are the thermos from any make. I have heard good things from JBL users, though they are hard to find outside mainland europe, and I've never seen one, let alone used one...
I hate Fluval with avangance though, so again I find myself in dissagreement with Tetra..... I find them stuborn to work on, they suffer channeling issues they can only go 2 weeks without a clean on my tanks and many sight reliability issues with them

Also, my strat pump came bust and the replacement only lasted about 4 weeks

After using
most other makes, many Fluval users don't go back... Shops stock them because they sell, and because Hagen (the makers) offer a generous discount on bulk orders... Try by all means, there are two experienced members other than tetra who use them (Miss Wiggle and Colin_t) but most dislike them (CFC, Andywg, both of whom have had them empty 75+g tanks for them....)
