This is my 29 gallon shrimp tank, it currently has 2 24" 2 bulb t5 no fixtures on it, all 6500k bulbs I believe. Is this medium light?

The first pic was taken roughly 10 months ago I believe. It started out with co2 and 1 30" t5 no fixture. Ballast died on that light, and co2 wasn't working right so I took it off.

I think it's grown pretty well considering the only thing I do is water changes.

sounds like medium to high light , the only way to really tell is with a par meter . Use this link to see a chart for diff lights

and this one
