got rid of cyano... now green algae bloom?

[scrapman]

I used Chemiclean to get rid of my cyano.... followed all instruction including timely water change
The cyano is gone!
Now, I have a green algae bloom.
Don't understand. My nitrate and phosphate are zero. My lights T5 run between 8 and 10 hrs/day.
Had anyone had this sequence of events: cyano gone/green algae bloom?

Try changing the bulbs on your fixture if they are getting old. Bulbs loose their spectrum after awhile and that could have caused the bloom. Has never happened to me before though.

All tanks have an algeae bloom.
Be patient and let it go out. The algea is there to eat something. Once it is eaten it will disappear.
Just try to cut out any extra feeding, to lessen added nutrients.

Thanks, I just switch from PC to T5 3 weeks ago.
Still a mystery.
My tank has been stable for almost 2 years/

Thanks for the uplifting message. I'll keep that in mind.

The simple answer is this:
The cyano was there because something was feeding it, and it was out-competing other algae forms. Now that the cyano is gone the other algae does not have to compete for the extra nutrients to feed it and it's growing.
You fixed the condition (cyano) without fixing the cause of the problem. Your nitrates and phosphates will usually read 0 while experiencing an algae bloom of any type, this is because the algae is using them and keeping them out of the water column.
Another issue can be the recent switch to T5 from PC without properly acclimating the tank to the new light. Generally you want to reduce photo period when switching to a significantly brighter light and increase it slowly over several weeks until you get back to 10-12 hours a day, this gives everything a chance to get used to the bright lights without over-feeding the algae.
Water changes, and reduced photo period should help resolve your problems in a short time.

Check your source water for phoshates. Are you using RO water?
