 Re: How To Keep Ferns?
I thought water changes weren't done on NPT? I haven't done any on mine for the first 6 weeks.
On the lighting issue the thinking behind the suggestion is this:
If you have algae in the tank then there is an inbalance somewhere, namely a defficiency. The longer the lights are on then the longer the algae gets to grow.
This is why you see much less algae in low light tanks. Not necessarily because they have everythin balanced but because the lower light slows the algae (and plants) growth down. It can be easier to 'dial in' the nutrients and CO2.
By increasing the lights more I am not saying the Fern won't pick up but if 9 hours ain't working then I don't expect an increase to improve things. However if there is algae of any sort I would expect an increase in algae. Maybe even some newer types appearing!!!
