Sorry...should have clarified better. It was a low light until I re-did it over New Years. Now it is high light with 4x65 CF 6700/10000k bulbs running for 7 hours and 2x65 10000k running for a 3hr burst in the afternoon. I am running pressurized CO2 with a dual bubble counter with 1 line running to a rex style reactor and the other I use a GLA splitter that goes to 2 diffusers. Also I am running 2 Fluval 404 filters, a 300watt Hydor inline heater and a 9watt UV Sterilizer. I use EI method of dosing with 50% water changes every week. I am also using Eco-Complete substrate.
I had to look up Walstad because I didn't know what you meant so I quess to answer your question that no it is not a Walstad setup.
