Should I turn on my CO2?

[winston77]

I have been running on low-tech for the past 1 year.

BBA seems to be on the rise though, nothing much has been done over the last 1 year.
Enough is enough of these BBA.

I know that BBA is caused by poor CO2.
I don't think circulation is a problem in the tank.

Should I cranked up my CO2 a little (0.25bps), highest (3~4bps), or nuke the tank with H2O2?
(FYI, I have upped the CO2 for the last 5 days already... )

Good CO2 with respect to the amount of light will stop the new growth of BBA but doesn't kill them. You need to trim them off on plants or bleach them on equipment and etc to get rid of them. The fact that BBA is still growing in your non-CO2 tank tells you that the amount of light is still too strong (CO2 demand still too high for the current tank.). Just get rid of your current BBA via methods as stated and then raise the light or ways to reduce the intensity.

you can also reduce the light by covering it with net.

My tank is already running on a single 25W light-tube.

Should I be reducing it further?

[barmby]

With regards to single 25W light-tube. Is your tank a low tech, and low maint tank ? Did you ever dose fertilizer into the water column ? I think the problem is not enough lights and there are excess nutrients in the water. Do note that BBA only need a few things to grow unlike plants who need everything.

[PeterGwee]

How big of a tank are we talking about?

Come to think about it, I do regular dosing of TMG micro and small quantity of NPK once a week to prevent GSA.

Its a 3ft tank.

[barmby]

Just leave it alone .. And the tank will end up like mine

[winston77]

Seems like I have been acting "too smart" all along, thought that dosing a little does help.

Question: Can I on the CO2 like 1 bubble per second for low tech?

Sometimes, cause and effect is being simplified too much. Lack of Co2 does not cause algae per se. Lacking of Co2 will cause plants to slow down in its photosynthesis cycle and thus nutrient will not be absorbed quickly by the plants, and thus will give a chance for the algae to grow on the excess nutrients in the water. So in the first place, if you do not dose ferts too much, this "lack of CO2" will not cause a problem.

On the other hand, if you crank up you rCO2 and do not have the lights to compliment it, or do not have enought nutrient to feed the new CO2 level, a nutrient deficiency will take place, and guess what?....algae will bloom also.

In Dennerle's guide, they used an example of just replacing a burnt out light tube with a new one, and they spent 2 pages explaing the chain of effects on how algae will bloom because of this little innocent change....its very enlightening to read.

Yes and No.

A deficit in carbon (usually in the form of CO2) is also guilty of algae formation and bad plant growth. Then also the assimilation process falters and sugars and other substances are again formed, which are released and activate algae. So it is important to ensure sufficient carbon. In a well lighted aquarium with fast growing plants the need can be large. CO2 is usually required to prevent problems.

thanks for the extra info

thanks for the discussion! i'm experiening the same prob! i just got a CO2 from NA today!
