Hi,
I just put the block in my sump, 120 gal total approximately. My NO3 is 20-30 ppm. Phosphate nearly undetectable (not ideal). I'm trying to lower my NO3 to 3-5 without dosing carbon.
**Anyone using this brick able to do that without using C dosing?
**How long did it take to get your nitrates down without C dosing? I'm thinking I should see something within 2 weeks (?). Maybe not down to 5, but hopefully half of what it is now -- so ideally 10-12. Maybe 5 after a month (?)
It looks like anything over this 20-30 I'm at now stressed my acros. Bnest not happy at this level now, but was very upset when it was 40 last week. I got it down by 25% water change. And I used prodibio, but that stopped lowering it below 20.
TY
