Amano's Tanks

That tank also got BBA pretty bad.
Amano does things by eye more than test.

If you met him, you'd understand.
I am more that way myself also.
I look and can tell what I need to add.

I am less assuming "perhaps" about why and the measurements I take however.
I'm not sure, never could get any straight discussion out of Amano.
I like him and he's a nice person, but not someone to hang out with and talk plants really, maybe, art, design, etc of the scape, photographing etc.
He's an artist making a living.
Not easy.

At lower light, then the demand for CO2 is greatly reduced.
Some suggest limiting nutrients and that reduces the demand for CO2, but many seen to assume it means that the algae are limited, that is not the case, like reduction in light, a stronger limitation with PO4 = a reduced demand for CO2.

CO2 is still the core issue for plants and the indirect algae issue.

You can see this both directions, with light changes and with nutrient changes, particularly PO4.

See this thread about going the other way and the bad assumptions/lack of good testing that lead many to a false conclusion:

This aquarium had a very bad case of hair and BBA and was taken down:


It now has been totally redone, all sediment removed and lower maintenance scape added.

They changes the outflow pipes from the nicer lilies to the Do Aqua which are weird.
This seemed to change everything as far as flow and did not distribute the CO2 very well.

The tank got very bad BBA.

My 60 Cube has a little residual left over from the move, I also added 2x the bioload. But the BBA is going away, no new growth, plants are doign better etc, CO2 needed some tweaking etc.

I eyeballed the CO2 100%.

Once things are fine, then I go back and measure the CO2.
Then I log that.

With a data logger, and CO2 monitor, I can do things like this:



The initial slope of this graph when the CO2 first comes on should be as steep as we can, then level off. Then drop fast after the lights turn off.

You cannot test this stuff directly, maybe with a pH meter/controller with data logging and use the KH, but few can do this with CO2 directly.

I eyeballed my tank/s, since I know what to look for and the fish are much more important to me than any nuisance algae I know I can get rid of later.

So they come first, then plants, and algae are last.
So forget they have fish and gas them with CO2.

I thought that was one of George Lo's ADA-spec tanks? Does he copy the methods precisely, or are there some differences?

Interestingly enough, when I was in there recently, it seemed sheets of BGA were more of an issue than the bit of BBA. I wonder what's changed.

Yes, that's the AF tank.
If you came by recently, then it's been entirely redone.

Generally, the folks that sell ADA follow whatever ADA tells them.
ADA also offers the LFS vendors training in Japan. Not sure about the cost/who pays etc.

BGA is common in ADA tanks, particularly in older tanks or where the ADA As have been used again. Pretty easy to figure out why that might me. Rather than adding more KNO3, they replace the sediment.
