Tank established 1/1/22
Been fighting PO4 lately, struggling to get it below 0.5 consistently. Other parameters are usually 1.025, Ca 420, Alk, 9, PO4: 0.5 - 0.6 (working on this), N03: 30. Did a water change, had a little extra water in after so I dipped out some with a container I have specifically for the tank. I think something may have been on it. EVERYTHING is exceedingly ticked off. I woke up today with my tank slightly cloudy, I suspect a bloom but not sure what yet, which is why I was doing a change.
Figured a 10% change wouldn't hurt, and I don't think that was it. I am afraid something got into the tank from the outside of that container. Would dried salt on the outside going directly into the DT cause this???
I'm running tests now, I'll update this as I get my results:
S.G: 1.025
Temp: 79
Ca: 400
Alk: 9
PO4: 0.47 - was 0.84 late last week. My API P04 kit was bad, read 0 nonstop so I even dosed PO4. Still 0. Got a hanna, 0.84...
NO3: 10
All fish/inverts accounted for so far. Fish do not seem affected in the least.
I just added a large bag of carbon. It's a 20g IM tank and this is the large fluval bags, 100g I think. Hoping to pull anything out that isn't supposed to be there.
Anyone see this before? Ideas what could've caused it? I'm prepping for another W/C now but I don't want to keep doing it if that's not going to help.
