Not sure what you would contaminate it with. All hydro systems have recirculating systems and they do just fine. All these systems including the underflow one require certain requirements to function properly. I believe your training in your current system will provide you the knowledge to adapt your system to a hydro system.
On another note if you want more height lower your tables by cutting the legs in half and replacing the wheels on the new bottoms. There now you have an extra foot. Hope that helps.

i wouldnt be able to lower the table since each table has rez tanks under them. thats why my measurements had to be that high. i dont really need much room. the plants seem to be stayin between 12-18" away from the lights
