changes all day long in a non CO2
, you are talking about a moving target.
You also need to address the KH
measure accurate when discussing 1-2ppm concentrational differences.
Many measure the KH
/pH and it says 210ppm or 80 ppm
, and the fish are fine and plants are doing well.
In other folk's tanks, this would = dead fish.
So good measure of the CO2
is critical if you want hard data, then you also need to measure the CO2
each 15 minute or so for a photoperoid the day of the water change and the day prior and up unit you see and/or predict the Algae bloom.
That's a lot of testing.
And it needs to be done carefully.
Until I get a house etc, hopefully next month etc, I'm not setting up a non CO2
tank abnd broke my sister's down recently(she lives too far away as it is for doing such a test).
I'm not worried, I see it working and have ruled out the other possible reasons proposed as to the cause of the algae blooms and falsified those.
This is pretty much all that's left.......and not one person has suggested any other alternatives that I've not falsified.
But .....until I really test it critically, I'm not going out on the limb just yet.
I know more of what it is not, than what it is.
The falsification prcoess is rather easy.
The why and cause is rather difficult to say the least, but it adds a lot to any theory building and ideas if you have something that appears causative.
NH4 was a good example.
I got lucky.
Why would algae, BBA, grow in both Non CO2
enriched tanks with poor CO2
stability and not in tanks with stable CO2
(either low or high) and why do they grow when we vary these parameters in otherwise stable tanks lacking BBA?
The observations will quickly lead you to rule out the past hythpothesis(excess PO4
etc), but one needs to know where to look and which observations are good.
They also need to be more creative than past folks about ruling out and testing such hypothesis. Then they need to propose an alternative hypothesis and see about testing it to verify.
It's not something you'll do in a day or two
The how is easy, the why takes a lot more time and energy.
