GFO question

That depends on how much phosphates you have in your tank and how long it takes for the gfo your running to soak up the phosphate. So run some gfo, usually about a cup or so for your 120gal, and see how long before your phosphate starts to increase, then it's time to change again. Most people change once a month or sometimes less.

Well as of today these are what I deem essential to testing...

Alkalinity
Calcium
Magnesium
Phosphate
Nitrates

So, that's 5 test kits.
