Phosphorus purchase

[scotty333]

Am I right in saying supermarkets sell phosphorus? When I do a near me Google search it brings up supermarkets
What’s it for in cooking?

Lost my copperband overnight , anemones suck into it’s hole

Kh 6.1
Calc 640
Salinity
1.025
Nitrates 75
Po4 .07
Mag 1560

Some tears in her fins

Your phosphate is fine and I would not boost it.

If you are looking for actual phosphorus, you are likely to get the FBI after you since it is used in incendiary devices. lol

Morning
But I’m dosing nopox, isn’t there a need for po4 to reduce no3?

Yes, but 0.07 ppm is plenty, and more will not necessarily make it any faster or more efficient. If it declines below about 0.03 ppm, then yes, it is worth dosing phosphate.

Ok boss cheers for that

Hi guys

This mornings results
Po .03 ( Salifert) Hannah reads lower )
No3 50-75

I can use nopox no more cos it’ll strip my last bit of po4 so I’m switching to vinegar until Monday I go the lfs , Agreed?
Unless nitrates come down with the vinegar

If the Hanna ULR phosphate test is reading under 0.03 ppm you are borderline.

That tester has an accuracy of +/- 0.03 so a reading of 0.03 could be 0.00.
Most folks aim for a reading of 0.05 to 0.10 ppm

I’m going lfs Monday so will check with hanna

Going to do a 30% water change too, I live 300m from the ocean so may collect the water from a rock pool that’s formed with high tide

 

[scotty333]

Buffered kh to 7.3
Why? God knows but I’m trying to get as many params in range

So just need now to reduce nitrates , calc and mag by water change

Looks like you are using a DSB, perhaps that has an impact on your Nitrates? Not sure if it does or not but I thought I would mention it to see if one of the other more knowledgeable guys knows.

 

[scotty333]

I have a dsb thread about questioning the flow since it only has a low flow over it because it’s 6” below the baffle

I usually usually buy Loudwolf but this looks like its probably good, maybe @Randy Holmes-Farley can confirm.
TriSodium Phosphate

Use “phosphate-from potassium phosphate” as nutrient

Is your tank having problems besides the high nitrates?

That's what I thought so I thought I'd mention it. I don't know enough about DSB's to be able to comment but maybe someone else does.

Corals and nem all shriveled up
Mag is 1560 and calc 640

How big is the tank?

 

[scotty333]

525ltr total volume

Did you test nitrates after you did the 30% water change?

Were you nitrates 30% lower?

 

[scotty333]

Not done the water change yet, Monday I’ll do it
