Yea black...Hmmm black airlines? They have those? And I thought I was stuck dealing with these clear ones I gotta disinfect every couple weeks. I don't cover my hydro ton either but that is something I should do as well... Always figured the roots get more oxygen that way
Also i have raisen my tent so all the rez are actually outside of the tent so the water isnt getting so hot.. I works like nothing else i have tryid.. I have NO problem what so ever with water temps..
