Hi,

I'm posting here for the first time for some advice on lighting my betta lifespace 35.

The tank is ~ 37cm x 28cm x 37cm in a 'deep' configuration. It comes with a waterproof light enclosure sitting directly on the water surface with 2 8w T5 lights (1 gro-lux, one factory fitted "white") and a mirror-finish reflector.

From what I've read this gives me 'low light' at very best...I have some Cryptocoryne Wendtii 'green', Staurogyne repens and Pogostemon helferi. The plants are growing (very slowly) in ADA Amazonian aquasoil with CO2 via a Flora-gro Co2 nano 50 (http://www.fishkeeper.co.uk/Whatsnewinfo.aspx?id=149). KH and GH are essentially zero, pH is around 6.2 and I dose daily with micronutrients, iron and NPK.

I'm trying to decide whether to:

1) simply squeeze another t5 in
2) make up a T5 size LED array to slot in between the current tubes
3) replace the tubes with a DIY LED or perhaps this http://illuminarium-inc.com/content/trident-series or an ecoxotic stunner strip? (if I can find a supplier/shipper to the UK)

Any thoughts greatly appreciated.

Thanks for the views!

@AzFishKid - I've had the tank for around 2 months now, but haven't had much growth of plants.

Perhaps I have unrealistic expectations but none of the P. helferi are much bigger than when I put them in, the S. repens has some growth, but isn't really spreading and the C. wendtii is growing (3 extra leaves per plant), but leaves develop brown edges after a couple of weeks (leaves currently 1 inch long max)

I swapped out the 'white' tube yesterday for an 8W powerglow (the other bulb is actually an aqua-glo), in the hope the spectrum change might help, but it does look a bit pink/blue for my liking.
