Where can I get a decent one at since I am looking at a new filter as well. I have tried WC and it does nothing. And what do you think is better diatom for UV comparing price and usefulness.I've only found two sure things that work for GW. That is a UV and a Diatom Filter. Water changes from my experience will not help. Sometimes GW goes away with time, but it could be a while. If you can set it up in line the UV is the best since you pretty much set it and forget it. I ran mine 24/7 without any negative effects on plants or put on when you need it.
Try here. It is for a Fluval filter but the diagram is what you need.Ray can you direct me to a link in what parts I would need to do this or can i just go to plumbing dept and get it from there. Is it just a valve thing that you can open and close pretty much. thanks
