Hello. I am looking for suggestions for powerheads for my 120 (standard 4 x 2 x 2) with quite a bit of SPS, with some zoas and LPS also. That said, I was hoping to get something that might also work for a larger tank in the near future (maybe a 200 gallon cube). Any input would be appreciated.
Powerhead suggestions for 120

Thanks for the quick reply. I can honestly say that after 7 years of reefing, I still don't completely understand Tunze products (i.e. the part numbers and what they stand for). To help me out, is there a chart? Also, how do I run the power heads on different voltage? It is good to know they can be adjusted for various tank sizes. Thanks again.
It is a pretty typical German numbering system, very much like Mercedes or BMW uses.
It is a 7 digit system the first digit is the product type, so 3 is filters and filter accessories, 6 is Stream pumps and Stream related products, 9 is skimmers, etc. The last 3 digits are roughly the flow in lph, though, in this case the number is more related to its ancestry, 6100 was replaced by 6101 was replaced by 6105. After that there is a decimal system and something like 6105.500 is an accessory or common spare part, (in this case, safety connector), items going to the second decimal are less common spare parts of parts of parts. Items going to the 3rd decimal are parts of parts of parts and generally uncommon and usually for internal use only in builds. Any xxxx.120 is an impeller or propeller for example and any xxxx.130 is an impeller or propeller housing, the first four numbers will generally be the pump it is for. When you use it day in and day out, it makes a lot of sense excepting very old numbers which don't really match the number system as well because the range was smaller and the numbering doesn't exactly match the current scheme.
Anyway 6105.000 is the 6105 Stream 2 pump, at 24V and 100% power it does about 3300gph. The power supply has a jumper setting for voltage and it can be set to 12, 18 or 24, these jumpers are included. The voltage sets the range you can adjust between on the controller so 30-100 at 12V is about 600-1800 gph and at 24V is about 1000-3300 gph.
