Ponds & reservoirs
Who can I go to for advice on installing a constructed wetland to clean up our runoff water.
Have other nurseries installed constructed wetlands to treat runoff water?
How large does my constructed wetland need to be?
What's the difference between surface-flow and subsurface- flow constructed wetlands, and which should I use?
What steps do I need to take to install a constructed wetland?
Do constructed wetlands remove nutrients from nursery runoff?
Do constructed wetlands remove pesticides?
What type of plants should I use to establish constructed wetlands?
How much maintenance is required to keep constructed wetlands working?

Control pH & salts
Is the pH of my water too high?
How much acid needs to be added to control alkalinity of my irrigation water?
Why is pH control important?
Will reclaimed water hurt my plants?
What salinity level is harmful to plants?
How can I reduce salts in a flood floor watering system?
Do you have any suggestion on what acid to use to lower pH so that we can use ethephon?
Why is the pH of my pond so much higher in the afternoon?
Should I add acid and chlorine into my pond?
Monitor quality

Contaminants: nutrients and agrichemicals
What are slow sand filters?
What properties need to be considered when choosing an ultracarb filter?
Do constructed wetlands remove nutrients from nursery runoff?
Do constructed wetlands remove pesticides?
What are the options for removing nutrients from my irrigation water?
Contaminants: particles and debris

Is duckweed bad for my pond? Do I need to control it?
Contaminants: pathogens and biofilms
How do I know if I am adding enough chlorine into my irrigation water to control plant pathogens?
Do constructed wetlands remove pathogens?
Which water treatment technology should I use to control pathogens?
When you treat the irrigation water to kill pathogens with quaternary ammonium compounds, for example, won't the residual present in the water kill the good microflora in the pots?
