Which Tunze's for my tank and cylindrical set up

[kdumph]

Tank is a 30 gallon cylindrical setup and I do have a flat back wall to hide overflow and return in which I could mount pumps on. Do you think they would stay put on a slightly curved surface?

It's going to be a mixed tank coral wise and I will be running an Apex controller.

Should I go with controllable 6055s or can I get away with 6025s? Also looking for mounting ideas. See link for photos of tank

Thank you for any help or suggestions!

You would not be able to control the 6025s, the most you could do is turn them off and on every 15 minutes and they will click and chatter briefly on every start. If you want controllable pumps, the 6055's will be the way to go and since you can vary the speed, an even lower flow is possible if needed. I think a single 6055 is the way to go.

Thank you for the quick rely!

Any ideas on the mounting?

If the surface is slightly curved, I don't see an issue other than possibly some noise since the rubber feet won't be in contact with the glass. Likely the back wall is the best way to go for that reason.
