How many hrs of light per day?

Anyone's opinions welcome: how long should lights be left on per day to
ensure that plants get their proper photoperiod?

THanks

In a word: Twelve

Actually I think opinions will vary from 10-14 hours, but 12 is a good
starting point. If you are running a whole lotta light... go for less
(maybe). Low light=longer (maybe).

Within reason, they don't care. Ideally they get 12 hr on 12 hr off
but a fewe hours either way doesn't really matter. Lots of plants are
grown under 24 hr light.

My tanks are low - moderate light plants and
I run the lights 12 hours daily, even in winter.
I suppose one could shorten the time in
winter. Maybe I'll try that.

All my tanks contain live plants. The 10's have those new screw-in
fluorescent bulbs = two 60w bulbs in each reflector.
The 5g has two 40s. The two 55's have those shop lights sitting right on
the rim with 2 40s each. I wish I could get stronger bulbs (like 80ws per
bulb) for these strip reflectors but haven't come across any locally. Since
I have plants in these tanks I change the bulbs yearly as they lose their
ummpt after a year.

day - cheers.

I keep the lights on for 15 hours plus and although some tanks need
"scraping" twice a week I don't have a great algae problem anymore. IME
it has been a matter of hitting the right balance with plants and algae
eating fish...Oh, and a little bit of manual stuff in the first place
but very little nowadays...I feed the plants but don't use a CO2 unit...

Works for me but very much ymmv

I've gotten rid of green water with nothing more than stepped up partial
water changes. The Vortex DE filter is excellent to remove floating algae.
