Tunze vs Hydor

[Darth Wader]

I run 2 koralia 4's and a k3 in my large tank and when I started a nano tank I wanted to try out the Tunze ph's so I picked up 2 of the 6025, took out some plastic cutters and modded them and they are amazing. I wish I had the money to buy 2 6101 for my larger tank. If I ever start another tank or have the money to put new ph in my big tank I will go with Tunze all the way. Rock solid products and they put out amazing flow. Cost more but from what I've seen its well worth the extra bux!!
