Flow help

[Asmoa]

I have a 30 gallon oceanic cube that's been running for over a year. I want to move towards keeping more sps. Currently I have 1 Seiko m620 (620gph - feels less) and 1 tunze 6015 modded (600~gph). Plus couple hundred gph return.

The few sps I have seem too be happy but does this seem like enough flew if I continue adding sps?

Any recommendations?

Thanks

You want a min. of 10 times the tank size flow rate. With SPS a little higher wont hurt...

The more SPS you add and the more they grow the more flow you will need. I am running 79x turnover in my display and am considering a little more. What you have now will be ok for a while, it is when they grow that it becomes an issue because they will block some flow in the tank. Corals depend on the flow to bring nutrients in and remove waste. I don't think it is very likely that you can have too much flow.

Thanks for the replies. Currently Id say the tank should be close to 45x turn over. I'm thinking about replacing the Seio with another Tunze 6015 or 6025 modded. Should add a couple hundred more gph, the Seio seems very weak to me.

The Seio isn't bad, I ran them for many years and the design is a solid one. The only thing with them is the size for the GPH they put out.

Two modded tunze 6025 will be enough.
