Hi,
I bought a light fitting today for the new tank I'm setting up and am wondering if you think that the tubes that came with it are OK for my plan or if I should go out shopping for a different tube or 2. I have read over the lighting sticky but it doesn't really answer my questions...
So the fitting looks like this http://www.trademe.co.nz/Home-living/Pe ... 151218.htm (but not this sort, this is not an ad!) and it's 50cm long. It came with 2 x 14000k T5 tubes and on the tubes it says 8W 220V 50Hz and they are 26.5cm long. It seems like a good amount of light to me, but is it too much for someone who won't be using CO2?
The tank it's for is 30cm deep (a bit less when gravel goes in), 50cm long and 28cm wide.
The plants I have so far are bolbitis and standard java fern (both staggered up a log that reaches the surface), riccia floating, duckweed floating, and hornwort that will be allowed to grow to the top. Will probably get some twisted val as well, maybe some moss to cover a stone or 2.
Fish are going to be killifish - clowns and aphyosemion of some sort.
Fertiliser will be flourish comp and excel, and no extra CO2. As the main plants are attached to the wood there won't be any extra fertiliser in the substrate.
a) don't want algae of course
b) don't want to make the fish need to wear sunglasses
c) want the plants to be happy enough
thanks
