The Tropica site lists certain plants as "very high light"

Anyone care to hazard a guess how this translates to WPG? I'm

assuming

somewhere close to 6 WPG?

I've yet to see a plant I cannot grow well at 2-3w a gallon.
All aquatic plants are for the most part, low light plants.

Yuo are welcomed to suggest a plant that cannot be grown at 2 w/gal,
I've grown close to 250-300species of aquatic plants over the years.
I've yet to meet one that does not do well at 2 watt gal.

I will say this: more light is not better.
More light= faster growth = faster uptake =more pruning and more chance
of algae.

It's my Water Hyacinth again. It was doing OK for a while, but it's slowly
going brown and mushy now.

Water hyacinth is a bit different than submerged plants. High light for
water hyacinth (Eichhornia crassipes) means the equivalent of outdoor
full sun. I have water hyacinth growing well in a pond where it gets
about 8 hours of direct, strong Southern California sun. It's not
growing as well or as quickly in my other outdoor tank where it only
gets 6 hours.

Is your water hyacinth sitting right under your light fixture where it
can get direct light all day?
