No idea if I have not enough light or too much

I have a radion g2 with wide angle lense over my 25g lagoon. Display is 13 inch deep. The fixture sits above the water about 10 inches. I run only blues, if I run both blues at 100% the intensity reaches 52%, if I run just one blue it's around 30%.

Depending on how old it is I would say it is likely plenty of light for that tank. However, the only correct answer would be obtained using a par meter and deciding what type of corals you plan on keeping.
