Hi,
i have had mu UAS running for a few weeks now and the growth i have isnt very good but i have some algae growing in my display tank ont he glass which didnt used to grow (its a new tank so im expecting its just sorting it self out) i also have diatoms on the sand bed but again i expected that because of thew silicas in the sand. i know this isnt the UAS fault just curious why its growing there and not on my UAS.

just wondering if this was looking ok for 3/4 weeks

so i think the mesh is 6x6 inches, air pump is a tetra APS 150, lighting is 1 philips tornado 23 watts.

tank stocking is 2 clownfish feeding some flake once a day.
