Thanks to those that responded to my questions! I have since
purchased a phosphate test kit (Aquarium Systems).
Aquarium=undetectable (one week after last water change)
As a reminder, I do a 20% water change every 10-14 days with 50/50
DI/TAP. See my original post for many more details if needed. Also
not reported originally was iron (Fe=0.1ppm).
From what I've read in the archives, this is quite a bit of phosphate
coming from the tap, correct?
Is it logical since I use 50/50 DI/TAP that I'm adding 0.3ppm to the
tank at water changes?
Can I assume the plants are using it up once in the tank? Or perhaps
more likely, the algae?
Would you recommend I use a phosphate removing product to remedy?
Any additional comments would be welcomed.
