I have a shallow 7 inch deep tank in my office and have a 2 bulb T5 about 3 inches over the water. (Sits on legs on the tank) Its too much light for the corals i keep and i dont want to build a whole setup to hang it. Ive been wondering if its possible to attach a diffuser on it and if it would decrease the par much.
I have a blue plus and an actinic, is there maybe another combo that produces less par? Ive been told by a source i trust 2 actinic wont work long term. Can anyone weigh in on that?
Thanks
Use a piece of frosted or tinted acrylic as a lid
