Re: [AGA Member] UV Sterilizers
Concerning the Aaron Glass question. Whether it does or does not
oxidize trace elements, UV sterilizers will "nuke green water, which
leads to a related thread:
GW happens when nutrient imbalance occurs.
In a very brightly lighted and heavily planted aquaria, plants will
have a high metabolic rate and will strip out nutrients quickly. Though
higher order plants may look good because of accumulated
nutrients/stored carbohydrates, the water column may be pretty much
depleted. Then, opportunistic GW algae will take off.
I had a 125 gallon heavily planted aquaria, overly illuminated. Once a
week I adding 60 ml Kent Freshwater Plant (Micronutrient supplement
with iron and K) and 60 ml Kent ProPlant (mainly nitrogen). This is a
lot. GW and other algae frustrations prevailed. I discovered plants
were using up these nutrients within a half a week. I cut light by 1/3.
Results = algae problems gone and need for fertilization reduced
dramatically. I use Hach digital colorimeter testing instruments for
Nitrate, Iron and Phosphate.
