Pump/Random Flow advice

[YourBelgianThings]

Hi

First time poster, so I hope this isn't a question that has been answered 1000 times already. We got a tank a few months ago. Fluval Evo 13.5/52 litres. All seems to be going well Everything in the tank appears to be doing very well and water testing all fine, both at home and when I take sample to our LFS ("if anything, your water is too clean...").

I want to upgrade the stock pump and add a random flow generator. My question is whether a sicce syncra silent 0.5, plus a VCA random flow generator (picture attached, I think) will be sufficient or will I need a stronger pump? (I don't want to add a wavemaker unless absolutely necessary, mainly for aesthetic reasons). I should admit that I have already ordered the 0.5 pump, but can send it back if I need to! If the advice is wait and see, then that's fine too.

The tank has:
* 4 soft corals (GSP. ricordia, kenyan tree and toadstool) in place for 2 months and doing well
* a torch coral, more recently introduced but looking very happy,
* two clownfish and 2 cardinal fish
* small clean up crew of hermits and an urchin.

Thanks.

There's no such thing as "ideal flow". It depends on what your animals have acclimated too and can acclimate too, and that can be very different depending on the species. As far as adding the random flow generator to your system I think you should take notes to see how your animals look before and after adding it to decide which is preffered by them and which do you think is more aesthetic.
