FWE does not directly harm anything, it's the toxins from the flatworms that cause the problem. I was infested. Millions, billions, zillions. I siphoned for a good 30 minutes but there were still a ton in the rock work. So, it wasn't the Flatworm Exit that caused the problems it was the toxins from the dead planaria, but that's a whole different subject.
My tank has been up for over a year now and I pretty much know what kind of colors it's capable of producing. Though the colors might not be the best due to the FW problem, I think I'll easily be able to tell if Zeovit actually did an improvment or not.
I was originaly going to first start off with CV and AAHC run that for a few months then switch over to full Zeovit but after thinking about it a little bit; by going Zeovit I will be turning off my ozone (which I like for health reasons) and removing phosban (expensive in itself) which I think are "bandaids".
I've found a lot of pretty scientific research over on that other site that explain why the Zeovit and specifically Prodibio (which is a basic Zeovit copy without the wide level support) systems work. If anyone wants to read it, PM me and I'll try and point you in the right direction.
As far as the tank picture... Not going to happen tonight. I stirred up too much sand while sucking up junk and my closed loops are just keeping it suspended. I'll try and turn the lights on tomorrow morning before I head to work.
