Green Water
I'm just wondering what the consensus on what the cause of green water is now a days?
I've heard everything from too much Fe, too much Nitrates, too much NH4, etc. I don't have green water currently, but I did get it a lot when I first got into plants a few years ago. I really struggled back then to cure it. Just curious as to what people think the cause is. -- Craig Brye University of Phoenix Online |

Trick question as green water is caused by algae! The real question,
what caused the algae? Craig Brye wrote: I'm just wondering what the consensus on what the cause of green water is now a days?

I had the same thing happen when I first set up my aquarium. Too many
nutrients in the water and too much light. I tried a blackout, water changes, etc. It got so bad that I could literally not see into the tank. It was completely pea soup. I finally purchased a UV sterilizer and the water cleared up within 48 hours. I've left it on ever since and have never had a problem with floating algae again.

Wow... I never knew that... Thanks for clearing that up!
Does this group have some sort of "profound statement of the year" award? -- Craig Brye University of Phoenix Online "Flatspin" wrote in message news:tO64d.217974$4o.129877@fed1read01...

I've heard everything from too much Fe, too much Nitrates, too much NH4, etc. I don't have green water currently, but I did get it a lot when I first got into plants a few years ago. I really struggled back then to cure it. Just curious as to what people think the cause is. NH4+ .......plain and simple when combined with higher light/CO2. You can induce it and kill it and then repeat this many times if you wish. I used both bioload and also NH4 inorganic sources such as NH4Cl, (NH4)2SO4 to check. A UV was used to kill the blooms and start again. It's always there, it's just waiting for the right conditions, namely NH4 and high light. Blackout will kill mild lower light cases, but at high PC lighting, it will hang on for months. Daphnia, Diatom filters, UV's , mechnical methods of removal(micron filters~5microns) are effective. FYI: Fe, NO3, PO4 have never been shown to induce GW. I've added these to rather high levels annd many do today and have no green water inducement or any algae responses. If you keep the other variables constant, then you can see what really cuases GW by trying out each one at a time. Regards, Tom Barr |

Thanks for the info... Makes sense. The first time I had this about 3
years ago... it happened after I had trimmed a lot of my plants and changed filter media in the same day. Dumb move, and also adds to your NH4 prognosis. -- Craig Brye University of Phoenix Online " wrote in message om... "Craig Brye" wrote in message ...
