Re: [GSAS-Member] Name the Plant Issue

["Clifford Miller" <clifford@clevergeek.com>]

I'm no plant expert, but the tall glosso is a classic sign of low light
(or emersed growth, which looks fairly similar).

What's the full name of the second plant? It looks like a short piece of
Egeria najas, which is typically very hardy under almost any condition.

Many people suggest changing out flouros annually for best results, and I
usually try to change mine out every couple of years.  You have plenty of
wattage for that sized tank, so it could very well be a spectrum problem,
which could also be the cause of the cyano.  As the spectrum of your bulbs
begin to lose intensity in the ranges they like, the vascular plants
become less able to process your ferts-- this means a lot more nutrients
in the water column, leaving plenty for the cyano which is less picky
about the quality of the light.

If you do decide to test changing the bulbs (and it does end up being the
cause of the issues), I'd recommend changing one at a time so you don't
shock your plants under the new "brighter" (to them) lights.

It's probably hard to burn plants with a power compact, but I've seen
LED's, halides, and hot5's burn plants to a crisp after a lighting
upgrade...
