Now............there is some tiny amount of BBA in this tank, but you really have to look for it and it is only on a few pieces of the wood in the current, not really anywhere else. I suppose if I wanted, I could really go after it more, but there's little point, it's not a nuisance.
Let's look at another tank:
This is pretty much opposite of the above tank, it's a Buce tank, full of slow growing Anubias like plants. About 25% of the light of the tank above. Same but even slower minor BBA on wood only.
I can kill it with H2O2 every 2-3 months, never an issue. I dose less to this tank, the demand from the plants is low, so there's no need to lard it on.
And then there's this tank:
Maybe 6 months ago:
Maybe 2-3 years ago?
It has BBA here and there over the years, but like the above tanks, tiny bit perhaps here and there on the wood, not the plants. But the last year or so, I've been unable to see any nor cleaned the wood.
Tanks all end up with about the same ppm's residuals over time.
All have a lot of shrimp, some snails, plecos, wet/dry filters, good general care.
These are F2's and the angels are F3's.
My non CO2 tanks have never gotten BBA.
All these tanks have PO4, a lot.
BBA on the hardscape is no different to me than any algae on the hardscape. When it gets on the plants or quickly covers things, there's a CO2 issue.
CO2 is not a simple thing, this is what gets intermediate and new folks.
High light also plays a role with algae woes. It all go back to simple stuff: good plant growth/care and good general maintenance.
No magic, no tricks. I go to the ADA store here in SF(AFA), and I see BBA on most of their tanks also. Sometimes on plants, sometimes just here and there on rocks or wood. They fix it or it sometimes nags them.
With clients, I cannot allow any algae on the glass or plants.
But some folks, myself included, need to learn through experience.
I did not believe my own advice today.....when I was growing plants 20-30 years ago
There are just some folks that will suffer and have to learn the hard way, other folks seem to get lucky, but is the typical bell curve distribution with most being pretty successful in the middle, and then the tails being really really good, or poor to really bad.
I suffered 3 years in the late 1980's-1990's with BBA, Amano said he suffered about 10 years. So that's some perspective on the pain and time frame in the past.
Client tanks provided good test since they often would run out of CO2 and then call me.....to fix the issue. Name the algae, they had it. BBA and on plants and the hardscape occurred after several days of no CO2. Not once, but every time for 5 different clients and myself. I've had many clients that are one or two time services to fix their issues, mostly BBA. Maybe 20 or so? CO2 every stinking time.
You might read the other thread I posted on with CO2, has a couple of graphs and the idea about flux and Fick's 1st law of diffusion.
