How Much CO2 Should You Add to the Water?
A common mistake is to try to achieve the water conditions one might aim for if keeping a fish-only aquarium.

Airstones and the Aquatic Garden; Gravel and Substrates
Airstones are not likely to hurt a slow-growing aquatic garden. Mixing substrates is OK.

Bushynoses and Swords
If you have a large Ancistrus population and the grazing wears thin, the recourse is to put in some bottle traps.

Working Out the Causes of Leaf Damage
I have an 80-gallon tank housing two medium severums, one medium blood parrot, one blue flash, one small Santaperca jurupari and one marbled headstander.

CO2 Basics
One of the things that plants need to live and grow, like all living things, is carbon. The least expensive way to set up for adding CO2 is with a fermentation container.

Make Sure Your CO₂ Recipe Doesn’t Use Too Much Sugar
I just started a 30-gallon plant tank, and the do-it-myself CO₂ system was adequate.

Beyond the Basics of CO₂: Using a Compressed Gas System.
I have a 92-gallon corner tank with a wet/dry filter and have had the tank

Plants from the fish store, especially when fresh from the aquatic nursery, are stocked with nutrients, and they can survive on these for several weeks before they use up these stores and become deficient in nutrients.

Don't Change That pH!
I have two blue gouramis, two gold gouramis, and three cory catfish in a 10-gallon tank.

Growing Plants Can Be High, Medium or Low Tech
I am often asked if there are really technologically advanced methods of aquatic gardening and if one is better than another for growing aquatic plants.
