So for the sump/ res I would like to use a 60g aquarium. I'll paint / cover it to protect from light.
I see the pump [ jeboa DC] and airstones along with a gyre for circulation probably.
Sponges for beneficial bacteria instead of bio balls or bio home blocks. The sponges are superior [ again this is what I know].
I have a chiller[ hopefully it works] but have no problem getting a new one. I know I will need it.
Water will run out of the room[ 20x6] to the res. in lung room by gravity. The buckets will need tables to raise them above the res.
That is why I lean to the 60g tank. It is 12 inches high. Like to keep it as low and large as possible.
For water monitoring I have a new HM500 just like SweetLeafGrow. Will get 2 if I run two sumps.
My fishy past has me loyal to HM, they make good equipment.
For the room I have AC/Heat unit that keeps room wherever I want,
AC infinity fans and controllers 4,6,8 inch.
I have a digitally controlled humidifier, and Inkbird monitors for my CO2 tank , the heat/ AC and for water temp.
I am still building in my mind and creating.
I don't mind investing in my hobby. I have not paid for pot in over a year, I have a NugSmasher, LevoC, 4-piece screens for sifting.
I enjoy my time with the plant.
I could run all the buckets together or the 11s and 44s separate.
They will only hold as much water as I desire.
So my next question is how much flow/ GPH per bucket for recirculating systems?
