I am upgrading my light on my 75 I just bought a fixture with 2x250W HQI metal halide and 4x54watt actinic. I have a t-5 217 system on it right now with 2x10000k and 2 actinic. Now my question is will that be to much ligh if I run both or can I take out the 10000k and switch it out for those purple tubes instead.
