We don't seem to be getting much rain so far this year so my rain barrel is empty which is the reason I'm asking about used tank water. So is it safe to reuse my aquarium water in my birdbath/fountain? I dose modified EI low 1x/week .. some Phosphate & Potassium, GH booster & Plantex CSM+B, no KN03. Also dose Glut day before water change but it should be gone by the next day.
I have 2 -75 gal & 1-18 gal that get 50% weekly water change. Usually one 75 gal has nitrates around 40ppm day before water change. Others aren't that high.
My fountain/birdbath is probably about 3-4gal. I usually add 2 gal in early afternoon because the birds have splashed it all out. And usually have to top it off early evening with another 1-2 gal. Just before sunset the birds line up to the take their baths. I need a bigger birdbath!
I did find something about Nitrate levels: Nitrate in public water supplies threaten human health if levels exceed 10 mg/l of nitrate-nitrogen (NO3-N) OR 45ppm nitrate (NO3). " from this source: http://www.caryinstitute.org/sites/...s/curriculum-project/4A1_Nitrogen_reading.pdf . Not sure of effect of 45ppm NO3 on birds but if less than that is ok for humans, should be safe for birds, right. ??
Just not sure about the rest of the ferts I use. Figured I'd ask here hoping someone knows before spending days researching it.
