from what I can figure out...floating algae happens like all other
algea....nutrient imbalances cause it...while a uv may kill all the floating
stuff...it wont do anything for the attached stuff...and the nutrients have to
go somewhere...

Hi Dustin,

Thanks for the reply - are UV sterilisers really only a temporary solution ?
Does the greenwater eventually come back ?

Cheers

UV STERALIZER

I had the same thing foor 3 1/2 weeks - even with 3/4 water change twice a
day for 3 days straight.. no help..

Added the steralizer... ran it for 3 days, did a 3/4 water change and im
back to crystal clear water... plants are pearling more since the light
can
get to them now..

Hi everyone.

First the specs of my tank:

Size: 200lt (approx 50gal) 3ft tank
Lighting: 6 x 30w T8 fluros of mixed color (5000k, 6500k, 10
000k)
=
180W
Filter: Eheim Professional 2224
CO2: Dupla system injecting through diffuser into filter
Substrate: 2mm natural gravel with laterite in the bottom 1/4
Fertiliser: Water coloumn none so far, susbtrate Jobes deep under
root
feeders
Fish: None
Plants: Fast growing stem plants

This tank has been setup for 3 weeks now (it has no fish) and was clear
for
about a week and now has a greenwater bloom in for about the past 2
weeks
it
so its definately out of balance. I have it heavily planted with fast
growing stem species and during the day they are bubbling non stop.

A few days ago I added some column fertiliser (pmdd) and some calcium
chloride to buffer the water. These are the measurements I took this
morning:

pH: 6.2
kH: 2.8 or 50ppm
gH: 90ppm
CO2: 53ppm !!!

Ooops I check the bubble counter and it was dosing at about 2 bubbles
per
second. I promptly turned it down a lil.

My natural tapwater is:

pH: 7.4
kH: 40ppm
gH: 50ppm

I just need some advice from you guys as what you would suggest to do to
get
rid of the greenwater and in general how I should go about dosing my
tank.
I have all the pmdd chemicals as well as flourish and flourish iron.

I look foward to hearing your suggestions and dosing reigemes so I can
get
a
better understanding on what I should be doing to keep the tank in
balance.

Cheers,
Jon
