The dimension of the tank are 48"Wx24"Hx18"D. Will be using pressurized CO2 and ADA aquasoil. I understand that light penetration may be an issue at 24"...and that HC Cuba is on the substrate. I would be prefer to go with an LED lighting solution. Would a single Finnex Ray 2 or Fluval planted 3.0 be enough? Or would I have to have 2 of these fixtures to make it work?
