Do i need a controler with my power heads

[BigReefing]

I have a 100 gallon tank. I am going to get 2 sieo m2600's. I Don't really want a controler. I read that sps need a break. What do you think. I am not getting a tunze they are just to much. Will sps do well with just 2 sieo's

Seios dont do good with wavemakers (controllers) but you can look into a hydor flo rotating head (not sure if they fit seios) which will provide random flow.

My tanks all use MJ, but do not have a wave maker or controlers. Everything growing OK so far. My 100 gal tanks have been running for 8+ years. My 120 for about 6+

The hydors do not fit. A controller will not work with SEIOS. If you have the cash get a Tunze.

If you go for the SIEOS just aim them at eachother so that you get a chaotic flow.
