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.
