Clearly the water suppliers there don't artificially raise the pH of their water to protect the copper and lead in water piping from erosion. Your pH would be considered too low for water in the...

A KH of 2 degrees dKH is good. Many, if not most plants do very well with that KH. A GH of 8 dGH is also good. It is far better to live with whatever your tap water gives you than to always have...

Today I found my bubble rate had dropped considerably overnight, and the pressure dropped to about 1-2 psi. I "pumped" the acid bottle to get the pressure back to about 5 psi, and it has been...

No, that's not quite what I hear Tom saying. He says that algae require such minute amounts of nutrients to grow that there is always more than enough "food" for them, no matter what the plants do. ...

That means you are measuring the tank water pH, perhaps. Most of the solutions that come with a drop checker are best thrown away. Instead, make some 4 dKH water, per...

From Mark Basil Jr.:
Nope. The "buffering" means holding a variable, like pH, constant with addition of chemicals that would otherwise change that variable. Alkalinity, bicarbonates, plus carbonic...

I haven't seen one of these CO2 reactors, but, as I understand them, they have a rotor in the top, where the incoming water makes it spin. That is supposed to help mix the CO2 in the water. I doubt...

That is backward. Using CO2 or Excel, etc. do not make the plants require a certain amount of light. Any amount of light is fine. But, if you use high light, that makes the plants try to grow very...

KH cannot be raised without also raising the pH.

It seems to have to be true that there is more than one way to stop BBA, since various people report good results with different corrective actions. The most "impressive" is Tom Barr's report that...

I keep mine "running" 24 hours a day, but with the difficulty I have in keeping the bubble rate up, it only runs at full output for 8 hours or less per day. I'm hoping that keeping the pressure up...

Yes, it goes to within about 1/8 inch of the bottom of the bottle, if not lower. But, it shouldn't matter, should it? If it was higher the acid would just drip into the soda water.

BBA selectively grows on non-growing parts of plants, or at least that is what I have seen. Anubias is a very popular target for BBA because of its very slow growth. Also, leaves that have stopped...

I know it regularly happens with well water, and some natural springs produce carbonated water. It is the open body of water that I don't see anyway for CO2 to remain at 30 ppm or so, unless there...

That would be the equivalent of a continuous volcanic vent supplying CO2. CO2 leaves water very easily, so something has to be replacing the CO2 that leaves the water for the CO2 level to remain...

What I see in the photos isn't "rotting", it is black brush algae. I'm surprised by that. Usually we see that much BBA when someone has a lot of light, no CO2, and no Excel in the water. But, with...
