Im new to planted aquariums. I have done saltwater for years. I am starting with 150 gallon 48x24x30H. I have flourite mixed with filter sand 50/50 on the mix. will add more flourite as money allows. for lighting I have a single 250watt MH that I salvaged from a salty tank. It now has a 6700k bulb. I will also be installing a pressureized co2 system in the next few weeks. I have a sump with a filter sock and 5 gallons of bio balls. My questions are mainly on lighting. Will the one bulb be ok or should switch to a 4 foot T5 HO fixture? If so, how many bulbs? As for now I have no fish and two bundles of hornwort. Tank is still cycling. Any and all advice is much needed and welcomed. Will post a pic of setup at its current stage.
