Question about DWC Top Drip Hydroponic Water & Nutrient Reservoir

[lvanh]

I have a DWC Top Drip Hydroponic System and I wanted to ask a question? I have a extra submersible water pump can I put this in the Reservoir just to keep the water circulating in the tank so the water and nutrients stay mixed all the time? I am new to this so this is why I am asking could I do this or should I even use my extra submersible water pump to do this? I would like any feedback I could get please! Thank you!

I have a chiller attached to my reservoir that keeps the temp around 70 F and of course circulates the water. Air bubblers also help the water to circulate around; do you have them in your reservoir? How are you aerating the roots?

Howdy Ivanh. Adding an extra pump will circulate the nutrient mix and help to keep it mixed up (not confused, as I sometimes am! LOL), but the added circulation will raise the temperature a little. I generally stop the circulation/ bottom feed pump after the roots get well established down into the reservoir. I have noticed a temperature drop of 1.5° to 3.0° F after turning off the pump. I use ice bottles to keep the water temperature below 70° F, so every little reduction in heat helps.
