Hey guys and girls thought i would upload a few pics of my basic and super cheap ATS that i have plumbed into my sump. Its feed by my 3600lph return pump and it has a 100w cfl cool white bulb that is on 18hrs off 6. I originally built the scrubber to fight phosphates as i dont have alot of room for a reactor. It works very well and i plan switch to a white led setup with blanking screens around the whole thing to avoid unnecessary algae growth in other parts of my sump. I have all the parts to build many of these setups so if anyone wants one let me know and il send them a kitset for $30nzd plus postage
