What kind of pump do you use? Also, do you have pictures of your overflow installation?

These all look to complicated and to elaborote for me, I was hoping to just put a through hull connector on a 70 liter container that connects to 8mm tubing and feed straight to an on off valve/quick connect that waters a row of 4 x 5 gallon pots and keep the rez about 3' above plant level and let gravity do the rest will that work? Is it really that simple or Do I really need a to use thick pipes and have one going into the top of the rez like that? I did

I didn't think you needed to use a pump with these things so it surprises me to see people using them here...

No, you don't have to use pumps. However, Blumats work best with more head pressure, which requires your reservoir to be significantly elevated. In order to achieve that elevation, it's easier to use two reservoirs and have the one that you need to refill down at a manageable level and then pump the nutrient to the reservoir that supplies the Blumats.

Wow thanks SO much for explaining that! You really helped.. How high do you think I should keep my rez? Will it be alright with the 8mm tubing connected straight to a thru hull connector? Thank you
