I am looking to trade a Koralia 4 powerhead. Its about 3 months old and works great. Actually it works too good thats why I am trading it. I currently have 2 of them in my 55 galllon reef tank and Im needing less flow. I would trade 1 of them for a Koralia 2 or 3. I would prefer the Koralia 2. If you have 2 Koralia 3s I would trade both Koralia 4s for both 3s. I only want Koralias no other powerheads. I also expect them to be relatively new and working perfect as this one is. Thanks
