probably someone with more knowledg than me will be along in a bit but from what Ive read its best to start off lower then build it up, only thing is im not sure if this applies to low light tanks?

I started my 60cm that im working on at the moment on 5 hrs and have moved it up to 7 once a couple of algae problems were sorted.

hi,
i would think that may be a little long to start with, but if you are getting no algae problems, brown diatoms being the most likely in a fresh start up then stick with it!

i recently started a new tank and it appeared fine for first couple of wks @8 hours (1.7 w/g (were t5 tho))
after algae started i lowered to 6 hours for a few weeks until it all settled down

Yeh 10 hrs even for a low light is prob a bit much. However, if you're not getting algae then its prob fine. If you start getting algae drop it back to 8hrs and go from there.
