Love my a.i. primes (5) on a waterbox 143 and a 55 gallon acrylic. Nice looking and great plants. Go to waterbox site, scroll to lights, and select lite, heavy or fish only light plan. My tanks are set to lite planted and running pressurized co2 with a .8 to .9 ph drop. Crypts wendtii form a dense, lush carpet. Like pendants vs conventional for access. No lid, run automatic top off for evaporation Very impressed with light.
