Thanks for the comments, I am kind of lazy so when I looked at either relying on water changes or going zeovit I chose the water changes. I have seen so many amazing tanks that use the old school water changes plus ca reactor and kalkwasser that it seemed like the best choice for me.
Having said that the new NP Biopellets offer a relatively maintenance free method of reducing nutrients and I will definitely be trying it out. I belive there have been some encouraging results using the pellets and the cost is far less tha zeovit.
I like feeding a tank so any additional nutrient removal system that does not involve large amonts of effort will definitley get my vote:
