Since typical drop checkers take 2+ hours to change to the appropriate color, most of the delay we see with build-up of CO2 in the water is just the slow response of the drop checker. With a good...

You can't measure the CO2 with any accuracy this way. You probably have 30 or more ppm of CO2, but the method isn't accurate enough to say what your actual ppm is.

I think I would assume that a 10% drop in GH and KH would not adversely affect the fish or plants, since rain can do that in nature. Based on that I would do roughly 10% water changes a few days...

I notice a lot of people want to know what light will punch through the water better. I believe it is based on the misinformation about how much light is absorbed by water. People fail to...

That is an interesting LED light fixture. It looks like you will need a lot of the pods to get enough PAR for plant growth. A 3 foot T5HO bulb produces about 3000 lumens, so you could assume that...

Algae infested leaves rarely recover, so removing those leaves is a good first step. Removing all dead or dying leaves is another first step - algae tend to grow primarily on non-growing plant...

Beautiful stand! Cherry is one of the greatest woods for any furniture. In 10 years that will be much darker, and more red.

I sometimes wonder if those who find a very high dKH for their water aren't actually reporting KH in ppm, rather than German Degrees. 29 ppm is about 1.5 dKH. Some KH test kits are calibrated to...

You want the plants to grow starting the minute you finish the water change, but you have removed about half of the nutrients that were in the water. So, you should immediately add the normal...

If your water is really way out of normal you can get RO/DI "filters" at a reasonable price for the relatively small quantity of water used in an aquarium. That is well worth it. Then you just fill...

You can do EI water changes every other week, but you will probably want to try to get closer to the amounts of fertilizers that the plants use up, so the build-up of unused chemicals will be less. ...

Yes, you can add the dry chemicals directly to the tank water. A very large number of people do just that, without consequences. It is the easiest way to dose, unless you are trying to dose such...

Why do you assume the resulting KH is too low? It is pretty hard to reduce it so the KH is too low for our needs.

That is probably a fungus growing from the piece of wood. You can scrub it off, and treat the piece of wood with boiling hot water to kill the fungus in the wood. If that is an algae it wouldn't be...

Carbonates plus carbonic acid (from CO2 in the water) are a buffer, which holds the pH at a value set by the combination of KH and concentration of CO2 in the water. There is always CO2 in aquarium...

You could have a CO2 leak between the bubble counter and the diffuser. I have had that before. It takes a very small leak to waste virtually all of the CO2.

The well known equation that defines the pH of water containing carbonates and CO2 is:
CO2 ppm = C x KH x 10^(7-pH) where "C" is a constant

You can rephrase that equation to:
pH = B x...

KH does not act as a buffer against pH changes when CO2 is added. Whatever the KH is, if you add 100 ppm of CO2 to the water the change in pH will be the same. With high KH the actual pH will be...
