The hood has a few holes drilled in to install an extra light listed below. I cannot recall if it made a big difference or not (sorry). But I was trying to keep SPS. The hardy ones did ok, others did not do so well.
Options are: 1) Table Ikea 30.5 42 13 = $20; 2) TrueLumen 12” LED Strip LIght $20 (does not add brightness but may add/fill in different spectrum colors); 3) PUKANI DRY AQUARIUM LIVE ROCK, 50 POUND from AquaCave (cost $177) never used selling $120.
I am in Arcadia; no shipping. I have more pictures if you are interested.
Thanks for reading!
