Hello everyone
We have a 125 litre tropical tank that is new and has just finished cycling today. For the last week we have had a green algae growth that first started on the bogwood and is now climbing the walls from the floor. Light coloured quartz substrate and tank is 35 days old from brand new. Temperature is 23°C. Ammonia level 0 ppm. Nitrite 0 ppm. Nitrate 0-5 ppm. 2 x 28 watt Juwel HiLIte Day lights on 8 hours a day. We are unsure whether it is beard or thread algae, or the dreaded cyanobacteria. When disturbed it will flow in the current.

Any help would be very much appreciated.
Thank you.
