Just curious to see what everyone’s Po4 readings are, if you do decide on testing the phosphates on newly made water please feel free to contribute....

1. What salt you use and actual reading
2. Salinity Po4 was tested
3. Which test kit used
4. Ro water or just tap
5. What city it was in.

Reason for this random question is because a friend tested .41

1. RC .41 Po4 new batch water
2. 1.025
3. Hanna Phosporous test
4. RO
5. Richmond

Very interesting topic...I’m using RC, I will test a fresh batch on Tuesday as I’m doing a WC.

Only thing I've ever checked is the salinity for many years. No issues, but wouldn't you know it, I decided to buy a batch of IO in the cardboard box instead of a bucket a few months ago and after a couple water changes, my tank started crashing..... in recovery mode now with a couple water changes using a new bucket.

I mixed up some salt (RC) and will test tomorrow. Funny thing is I do WC biweekly and my nutrients have stayed the same for the longest time Nitrates 2-5ppm (Salifert) and Phosphates 0.02ppm (Hanna Phosphate checker). I tested today like every Sunday and noticed an increase in my PO4 at 0.10ppm.

I recently bought 4 new pails of RC on Black Friday... and I have done two WC’s using one of the new pails... I’m hoping it’s not a source of phosphate as mentioned above.

Ok so I tested my fresh batch of RC before my WC and this is what I found.

1. RC / 0.00ppm in new batch.
2. 1.026.
3. Hanna Phosphate Checker.
4. RODI water / 0ppm phosphate off line.
5. Edmonton, AB.

Seems like that bucket is not affected. When I crack open another new bucket I will check again.
