Ska's 28 Macro Algae Display

[OCDP]

Just my two cents, but I have a Koralia 4 in my 20g. I also have a Seio 820. My 20g isn't as long as yours, but it's do-able. It all comes down to placement of the pumps, and rocks. I would say go with more flow than less.. but that is my opinion, as you can work around it.

That tank dose look pretty shallow though.. You'd probably have to set the K4 on the bottom facing upwards a bit.. either that or go with 2 Seio 820's. I love the Seio's .. I think I prefer them over the Koralia. They seem more solid, and keep a steady constant flow, whereas I find the Koralia all over the place, with weak spots and strong spots. And yes, they are large, even more so in a small tank!

Also.. to add, if you want something big and pink, on the verge of red as a centerpiece.. I'd recommend a nice big Brain Coral. They are pretty easy to keep, very hardy (at least in my experience) . Blue corals seem somewhat rare, but ric's are commonly sold in blue. Blue zoo's are amazing too.
