My Tank Thread
Thanks for the chart. Never saw that before. The GFO is in a dedicated reactor. Charcoal is in the other reactor. I will reduce the amt of GFO. I only allow the flow to be enough to just stir up the GFO.
Your welcome.
Used to use the math formula from ppb to ppm until I found that chart a few years back and matches the math conversion to a tee.
You can click on that chart and download it.
You seem to be at .06ppm so I would keep it tuned in with the GFO media amount and flow rate that you already have.
fwiw:
The new Hanna ULR ppm checker HI774 is really nice and it won't time you out from step one to step two as fast as their ULR ppb checker does.
Have a great Labor Day weekend.
