I have about the same tank size and I use two Maxi-Jet 1200
(one on each end) along with the pump from my sump and Magnum 350. I just added a 228 power sweep
but have been disappointed in the performance of it compared to the Maxi-Jet ph
. Overall you want to turn your tank over around 10-15 times per hour or more depending on what you plan to keep or in your case around a total of 2500 to 3000 liters per hour. Since your Eheim 2215 does around 600 liters per hour the two additional Maxi-Jets should be fine.
Also you may want to get about another 20 lbs of lr
for your tank to help with filtration.
Forgot to mention the Penguin 1140 Powerhead
. It does 300 gph
\ 1135.5 in Litres and is also a very reliable ph IMO
. I have a 10 year old 1140 that I use to circulate and pump my premixed sw
and itâ€™s still going strong.
