How do you lower nitrates when phosphates are 0??

hi Garf

As much as negative, negative, not, but 2 sps if they hit something, but also coincided with the new implementation of the LED, so do not know who is causing real, look at the difference of the two types of lights

The no3 not drop almost anything

[tebo]

Well next week I will start with potassium phosphate to increase the phosphate

My no3 are: 30ppm
As phosphates are: 0.00ppm

I will obviously never be able to download the no3

Your phosphate is not 0. It is being consumed by algae before you can test it.

I would do some water changes instead. But each to there own.

From what I can tell in your photo you are running a barebottom tank. The reason most people do this is so they can push massive amounts of flow through the tank without causing a sand storm. Yet you are not doing this. I see detritus build up on the left side of the tank and a lot of algae on the right side . Clean the detritus and get some powerheads going. Maybe harvest the algae off the right side manually?

Yes, I know this, so I'm uploading is artificially phosphate, to lower the Neo3,without sufficient phosphate for algae this does not consume adequately no3

I have understood that the algae consume a 4:1 ratio No3: po4 it
is that true right?

I have two closed loops each with its hammerhead, believe in my tank does not accumulate debris, that you see on your left side you have to scrape to remove,

and algae on the right is a rock that came loaded with phosphate and am recovering

Read the full post and will understand it comes to this situation

There is plenty of PO4 with every feeding, every pooping, every peeing, every coral mucus, etc.

Algae consumes N and P in the same ratio that food provides it. It does not matter what the ratio is. What matters is that the more you feed, the more the algae grow.

It's simply a matter of too much food going in, compared to how strong your scrubber is. Flow in the display is also an issue, because if the ammonia, N, and P hit the problem areas before they get to your scrubber, then the problem areas will get the nutrients first. So if your scrubber is weak, then stronger flow to your scrubber will help. If your scrubber is very strong, you may not need strong flow to your scrubber.

It's all about how long nutrients stay in the water before they are consumed by something.

If I know this whole process I have enough time following the ats, learning from all your post

My aquarium has always been low in P and N through the ATS, the problem is that a few weeks ago accidentally spill a little over 500 ml of a preparation of food, this caused the imbalance that I have right now

No3: 25ppm Salifert
Phosphates: 0.00ppm hanna

Then I started adding potassium phosphate to raise po4

Is this OK to do

[SantaMonica]

accidentally spill a little over 500 ml of a preparation of food, this caused the imbalance that I have right now

Food is not "imbalanced" in N and P. It has about the same "balance" as algae.

No do not add P.

Just continue trying to make your scrubber stronger. Or, just let it run.
