Hi all,
I'll do that and take it down to 5 hours and less intensity.
Honestly don't, you run the <"
real risk"> of not providing enough light intensity (PAR) or light duration for your plants. Plant growth looks good at the moment and that really is the most important thing. Edit, what
@bazz says.
Humans are incredibly poor at <"
judging light intensity">, but we can take that variable ("
lack of PAR") out of the equation by <"
using floating plants"> (not CO2 limited) as both <"
nutrient reducer"> and <"
net curtain">.
The basic question is:
Why would 19 hours darkness benefit an organism that uses intense light (and CO2) to make its food?
My worst fear from the start was getting BBA!
You are always going to <"
end up with algae">, it might be possible to exclude BBA for a while, but diatoms, cyanobacteria and green algae (Chlorophyta) are <"
universal in fresh water">, I know its difficult, but you have to concentrate on plant growth, that is the thing that matters, not any algae.
I'm <"
deeply cynical"> but I think that the aquarium products industry has an interest in demonising "
algae" (or "
pest snails"), because that gives them an endless chance to sell useless products.
That looks like start of BBA and unfortunately no one here or anywhere else can tell you why and how.
We have some threads <"
What exactly causes BBA?"> & <"
What exactly causes BBA? Part 2 - Bacterial imbalance">, but not any definitive answers.
We also know that BBA can mysteriously detach and disappear, but again we don't know why <"
Iron, Flow and BBA">.
