I am setting up a 20H Gallon tank, its 24x13x16. No sump for now. I not sure what powerhead to get for this size tank. Tried Maxi-jet 600 and Koralia 1, both seems to be two much current. Goal is to create enough circulation and movement.

No Sump

some frags of SPS, Blastoma, Zoos, ricordia, Clove Polyps, Candy cane.
Plan to get frogspawn and Green Toadstool.

	SPS Small Polyped Scleractinians - Sometimes known as Small Polyped Stony corals. These are hard corals that have extremely small polyps. They are typically on the difficult side and require Metal Halide lighting or dense Power Compact or T5 arrays. These corals are prized for their rareness and ability to be easily fragged into multiple colonies.

It may be difficult to provide ample circulation/movement for SPS, while also maintaining candy canes, toadstools and frogspawn in the same 20g tank.

Yes, I am trying to balance the right movement. The Maxi-jet 600 is 160 gph.
I tried adding Hydor on it and it slows down the movement a bit.

More pumps meant less movement?!

[alfani]

place your Hydor on bottom corner and use mj near the surface to make surface waves

Thanks, I'll try that. My Koralia 1 ( 400 gph ) was also too powerful in that tank. My cloves couldn't open.

It might not be the flow that's keeping your cloves closed. I have the same tank with a tunze nano 6025(about 600gph) and a mag 5 I think on the return and it's still not too much for the tank. Softies and LPS are fine. Zoa's as well....

Like Dean said, how does adding another pump make the movement less?

	LPS Large Polyped Stony corals – In the aquarium hobby this is a common division of the species of stony corals based upon the visual assessment of the size of the polyps. Corals in this category were among the first stony corals to be kept successfully in captivity and include many very beautiful species. Commonly kept Genera include Euphyllia (hammer/frogspawn coral), Favia (brain coral), Plerogyra (bubble coral), Lobophyllia (meat/tooth coral), and Caulastrea (candycane coral). LPS corals also include the popular solitary non-colonial stony corals such as Fungia (plate coral), Cynarina (button coral), Trachyphyllia (open brain coral), and Herpolitha (tongue coral). Like their SPS counterparts, LPS corals require good water quality, intense lighting of the appropriate spectrum, adequate water movement and regular supplementation of calcium.

Finally got it. Position the Koralia 1 on upper right hand corner shooting across at angle. All corals looks happy so far.
