I'm no expert with SPS, as a matter of fact I just added about $250 worth of SPS frags in the last week and so far so good. I did a test with 3 diff types of SPS and they did great for about 3 months so now it's time for the real deal. I also just setup my Ca reactor last night, that was exciting. Anyways IMO I would say 72 will be plenty for a 125. If u wanted to be extra safe and have a full spectrum setup i would consider 90. Worst case you can just dimm them down. There are diff drivers that will work, do some research, they were a little tricky to figure out. If ur running an Apex make sure to get the ELN D drivers, as they are 0-10v analog dimming signal. If u want to dimm manually, then go with the reg maxwellen. Good luck
