powerhead question

[J.R.L.]

what size koralia powerhead should i get for a 20 gallon tank...tank dimensions are 30x12x13....i have some small corals and such like frogspawn, bubble coral, and zoanthids...like which GPH rating should i use?

Go with the 2. You can then position it to maximize it's flow across the entire tank.

I don't know anything about that brand, but for that size tank I would recommend something in the 170 gph range.

ok thanks for the input...i think ill go with the nano thats 240gph or koralia 1 thats 400 gph so i can use it when i upgrade to a bigger tank

I would stay away from the K nano. The gph is way under rated for a 20. nano says it all, best suited for a 6-12g. I would go with the K2. I have the nano and its in my fuge for some extra tumbling of my cheato.

I would at least get a 2. The K1 is very and i mean very weak
