Just as it sounds, my nitrates spiked to more than 10 ppm and my phosphates only increased from 0.02 to 0.04 It's been a week and the reduction of nitrates not been very significant, I recommend you, the only let down or what???
thanks

What's been a week?
Usually it's the other way around

...because of natural denitrification. If you have any N I would say look at the scrubber, something is not working right. Is this your waterfall or UAS?
Hi Garf
16ppm to 14 ppm in one week
Hi Floyd R turbo,
My mistake was feeding at one time about 30 ml of a preparation of shrimp, well it broke my device and it was a disaster
Then my phosphates did not rise much but my nitrates if
The ATS is well, well grown a little black algae on the sides
I do let him down alone, I worry about is the low proportion with respect to phosphate
Shrimp has one of the lower phosphate to protein ratios, according to the Randy Holmes-Farley article from a few months ago. I'm not sure if this would mean that less P and more N would enter the system and throw everything in that direction. That would seem to go against this running philosophy about the redfield ratio of N:P in food and in absorption of nutrients by algae.
I have long wondered if there is a connection between different food blends and the ratio of N and P and how this might affect long-term water chemistry and scrubber growth. I recently switched my DIY food recipe to include a much larger proportion of shrimp, as well as daphnia and rotifers. I wonder if that will lower the excess P inserted into the system...
Floyd greetings, I can not really vouch for anything scientific hehehe, but I came with stable values of between 0.02 and 0.04 phosphates and nitrates between 1.1 and 3, after the disaster as if shot up nitrates and phosphates remained stable the mixture contained a higher proportion of shrimp than anything else
regards
So now you have high N and low P? I would keep feeding like normal and monitor it.
Hi floyd
yes, high N and low P
Well I will stay with the routine of feeding and monitor it the N
Tebo - is this problem affecting your display tank negatively ? I love pictures, have you got one of your tank ?
