I am so thankful to have found this thread! Thank you to everyone that has contributed such valuable information about Beamswork light fixtures. I have read all 24 pages here, and it was a lot to absorb, so forgive me if I am asking for redundant information...and also if I get a bit long winded here lol.
Long story short, I moved from Louisiana to Georgia and downsized to one aquarium. It was damaged by movers, but holds water so for now it's an unscaped holding area for the anubias, hornwort, duckweed, and java fern that made the move with me until the reimbursement check comes in and I can get new glass.
My tank is 25 inches tall and 36 inches long, 65 gallons. I looked at the chart that was posted, and am unsure if the "pent 0.50w timer 6500k" fixture is the same as the light that I currently have or not. It is a DA 36" 6500k .50w fixture, it does have 5 rows of white lights with a few blue ones mixed in, but it does not have a timer. It seems similar enough to me for the information in the chart to be accurate for my setup, but I wanted to ask rather than assume. My current low light plants are doing great with this light and I have no algae issues. I would like to try for a carpeted look in the new tank, maybe microsword or dwarf hairgrass, monte carlo, etc but I don't know if this light by itself can support that type of plant growth. I understand that at a certain point, CO2 injection becomes a requirement. I live in the north GA mountains, and every winter we have 2-3 power outages due to high winds and/or ice. We have a generator, but I'm still not sure if a high tech system would be the best option given the pretty much guaranteed outages that we experience. I am wondering if I buy an additional light exactly like the one I currently have, would it be possible to maintain a carpeted aquascape at 23" depth with ThriveC and ecocomplete soil or would I be sliding into CO2 territory? Has a carpeted scape ever even been successful without CO2 injection, or does it usually end up being a temporary success story for most folks that try it?
