rdwc warm nutrient water

I'm running heavy 16 idk if i wana use h202 cuz itll pretty much kill my heavy 16 prime so that would b a waste of my money.. what can i add to my res when i do my res changes should i jus run my entire heavy 16 line alone w nothing else? Or should i add a beneficial if so whixh one? Or which...

How about great light, air circulation, continuous 60F air temp on top and controlled 82F nutrient water temp for root zone and microbe colonies. Foliage likes it cool, warm water insures higher metabolism for roots and microbe growth? Sounds like a winner to me. Thoughts and opinions? J
