Actually, @Essjay, I think we're on the same page here. I bought the 207 rather than the 107 for its larger filter canister - 5.3L instead of 3.7L. This I decided would mean more media volume/surface area for the water to pass over and thus longer maintenance intervals. The quoted 'basket...
I found the Oase internal filter that came with my tank was ineffective and ended up needing to be rinsed out every three days. Also, taking the thing out all the time disturbed the plants etc. I've just upgraded to a fluval 207 external filter. Time will tell but apparently I'll only need to...
For the record, I'll mention my first impressions of the Fluval 207. Installation was easy, but I thought the brackets that mount the hoses to the tank were cumbersome to fit and bulky. One of these days I may look into some alternative inlet/outlet apparatus.
It's noisier than I had hoped...
I bought the 207 rather than the 107 because I wanted the higher filtration capacity (a reaction to having to clean out the old unit every 3 days), but was worried about flow. But then I noticed you can adjust flow rate on these things. In fact, the flow rate on this 207 doesn't seem as fast...
Good suggestion - unfortunately I'd already fitted the 207 by the time I you posted this and I've discarded the old filter unit. I stuffed two of its sponges into the new unit, in with the ceramic tube things.
I've just ordered a Fluval 207 external filter pump to replace the hopeless internal unit on my aquarium. Here's my question: what's the best procedure for migrating from one to the other, without risking de-cycling the tank? I don't really want to run both pumps at the same time; as it is...
The lights are a pair of full spectrum LED tubes (Oase Highline Classic LED 70). They're so bright I can't run both of them for long. I'm waiting till I can afford something like the Fluval Aquasky to replace them.
@NannaLou -
The Green plant on the right in my aquarium is Micranthemum umbrosum, I've learned:

I wish I did. The guy who originally bought the aquarium couldn't remember what the shop said it was. All I know is it grows at incredible speed, and spreads... The gourami love to hide in it.
No question - just thought I'd update you all on my aquarium in light of the various issues I've raised recently.
First of all, as predicted by all of you, the third Rainbow Dwarf Gourami I bought died. However, the other two have settled in nicely with no signs of aggression toward each other...
which shows the other problem new fish keepers face - contradictory information across websites and forums. Several 'authoritative' websites (such as fishkeepingworld.com) describe dwarf gouramis as "peaceful and tolerant" and/or "timid"...
