Can there be too much flow?

Watchm@n · 02/09/2017, 10:48 AM

Hello all

A question on flow, as the title says.
Currently have a 150 with 2 jebao rw8 on either side (length wise). They are not paired and are individually set to else mode (random wave pattern) is there any benefits to pairing them in else mode at all?

Back to the original question, I'm thinking about possibly adding 2 more maybe "mini" wave makers.. either hydor nano 900 or tunze nano 6015 and placing them facing foward, so towards me if I'm standing in front of the tank.

Currently have softies and lps in the tank but will begin adding sps relatively soon.

I can't really tell if I have any dead spots right now as I don't really broadcast feed to have any visual indication of how food flows about...

Thanks in advance and any suggestions or recommendations welcome

I also have a 150 with 2 apex wav pumps at opposite ends and think I am stirring up the sand with them set to 25% max with inverse and various programs. Curious what the ideal flow is also.

You can get to too much flow, but very few ever do. If you use pumps that have speed control (like your Jebaos) if you get to the 'too much' point you can always turn them down some.

I have a 125g (6'x2'x20") and I run 2 big Jebao wavemakers on the back wall (painted black so they almost disappear) and a Crossflow on 1 end. I tried 2 Crossflows and that really was too much!

Flow can be too strong, especially with LPS. You can't have enough water movement though... and I think that's an important distinction to make.

The trick is to finding the balance where you have good water movement throughout the tank, but where no corals are getting "blasted" by too strong/direct flow.

im having an issue with 2 much right now! I added the advanced gyre controller to my 2 Gyre XF150s. Since the both keep both pumps on at same time it has caused the flow to crash in the middle of the tank and stir up sand in the middle as well as cause some of my chalice and acans in middle of the tank to peel back flesh or close up. I am going to go back running them individually setup on my apex to turn one on for an hour, then off and other on so only 1 is ever running at a time.

I totally agree, and have worked hard to ensure this.
