Currently at Marine Fish we have 1 Koralia 3 Powerhead for $40, 4 Koralia 1's for $35, and 3 Koralia Nano's for $30. These are Koralia powerheads that ONLY plug into the Koralia Wavemaker Controller, which we do not have in stock. These are net prices, so unfortunately there is no ARC discount like we usually offer, but they are still a great deal. Come by soon because quantities are limited!
