phosphate problem

arman · Jul 16, 2016

Hi guys.
I just purchased an acro 2 months ago.
I t was doing good but i saw him bleaching and i tested the parameters.
And i think i have po4 problem.
so i tried testing my ROs po4 too.
And i saw it has po4,but the color is something that is not in the card.
I wnted you friends to help me.
Thank you very much.

I forgot to mention.The color is at first bright but after a while it goes turbid.And at last it starts to deposit at the bottom.

The right one is the befor ro no3.

As you see the color is getting turbid.

And the deposition

The left one is my tank,then ro,then befor ro's po4.
Is the api test for both fresh and salt water?Because my tank's test has no deposition in it.

The amount of phosphate is 0 ppm TDS RO/DI is not important and I would not try to measure it.

Is it 0 ppm TDS?

The TDSis 15.
When i mix the RO's water with salt the test results about 0 phosphate.

Imo those tests are highly inaccurate

Sorry the cam is not good enough.
Im just confused.
If the fresh water's po4 is high so why when i add salt it does'nt show high po4?

Randy Holmes-Farley · Jul 16, 2016

Is there a DI being used? If so, replace it when the TDs rises to 1 ppm.

Maybe the kit is not actually detecting phosphate in your RO water.

What is DI?
I thought its sth in RO.Is it something else?Ive heared something named resine that is placed after ro?

I had a po4 from my top off water anytime my RO/DI system went over 0 ppm. Although I didn't know what my problem was because my po4 test kit had expired and was giving incorrect findings. My recommendations are to add a DI stage, replace your RO filters and membrane so your ppm is 0 and check your expiration date on your test kit.

This explains what RO/DI is, and if you are not using DI, I'd recommend it:

Thank you for helping me.
I didnt have tds meter so i got one 2 weeks ago.Guess how was ro's tds,150.Not 15.
So i changed my RO's filters so it dropped to 9.
I got a DI too.
So the tds is 0.
But as i use this water my red blasto mussa does not open like before?I have a polyp that some of its polyps does not open too.
What can be the reason?

It is not likely the water itself. Maybe something else has changed or is bothering it.

How long have you had it?
