Hi all first I want to say that this is a great newsgroup !!

I am experiencing a greenwater problem at the moment and thought someone on
the list may be able to offer some insight into it. It is the only sort of
algae I have EVER got in any of my planted tanks and is a real pain (not as
bad as others though). Here are my tank specs:

200lt
6x30w fluro lights
CO2 injection approx 1 bubble / 2 sec with Dupla system into intake
Eheim Professional 2224
(the water is really soft here.. carbonate and general hardness both about
40ppm.. i have been buffering it)

I have just moved and set it back up about 2 weeks ago. It has a lot of fast
growing stem plants in it and for the first week things stayed crystal clear
and the plants were bubbling profusely. They are still bubbling but the
water is a hazy green. I haven't been adding any water column fertilisers
and only have some laterite mixed in the bottom 1/4 of the gravel.

I am hoping at the moment that it is just a phase in cycling and once the
plants really pick up they will out compete the algae. I think ill try and
do a big water change and see what happens (I have no fish in there at the
moment)

Cheers,
Jon
