Sunny,
Whats your opinion of GFO usage with a dosing system such as yours?
My system is almost 3 years old and I am interested in going to bacteria to give it a kick and long term success. But I have always used GFO, so I am curious how it plays into it.
Great thread man, and nice to see other people kicking butt with T5's! Been AWOL for like a year and it seems like many people have taken a liking to them.
Welcome back!
Some people say that you shouldn't run GFO, and others say it is no problem. I have tried it both ways and see no problem with doing so IF you still have some stubborn PO4. If your system is at 0 PO4 then there is really no need to run a GFO.
I have some GFO in my salt water mixing tub and will run the GFO in the main tank whenever I do a large water change or siphon out the sand.
I say keep a close eye on your levels. Every system is different and you will have to sine tunes yours accordingly.
