Pukani rocks

[hyla84]

Hello guys,
No matter how much rowaphos I use every time it goes 0.03 and when I remove it increase straight away.
Same with no3 still high since I started my tank.
Done several water changes but still po4 and no3 high.
I've read about pukani rocks that usually gives this issues.
What to do?
Thanks

Is there live stock in the tank?

Some solutions;
Remove the rock and find a new type of rock.
Remove the rock and use a lanthanum chloride bath.
Keep using rowaphos.
Start carbon dosing.

.03 phosphates is good. What are the nitrates at?

Po4 003 when I use rowaphos nitrates 50 I guess tank seems fine apart that every little moves that I do I loose corals...

Did you cure the rock before putting it into your tank?

Lanthanum for how long? Where do I can find it? I've paid for them a fortune and I don't want to loose more money that I already did...

Here is one of many threads here

Lanthanum Chloride

Well I think it's finally time for me to throw my hat in the lanthanum chloride dosing ring. I have pukani rock in one of my displays that I believe to be a PO4 sink. I am debating either dosing in the overflow and running a 10 micron filter sock or removing the rock and dosing in a curing...

No because who sold me told that theiy where alive...

Sorry but I didn't get it. Can I use lanthanum in the tank with corals and fish or do I have to take the rocks out and cure them in a bin?

No

Really .03 phosphates and 50 nitrates isn’t so bad that you need to break down tank. 50 is high but unless you have major algae issues this is manageable. Clean the tank/sump/pumps everything. Blow off rocks detritus and do a large water change. Run some cheato and stay on top of maintenance and the system should balance out.

Make sure you are using RODI water too

Po4 003 when I use rowaphos, if I remove it po4 are 0.30 after a couple of days....

The LC will not be effective at removing P04 from the rock unless you can remove the rock from the tank. It will still leech out unless it is stripped. I would just continue to use rowaphos for P04.
Do you know where the nitrate is coming from?
Do large water changes help with the nitrate?
Could you be over feeding?
Do you vacuum the sand bed every week?
Are you using a protein skimmer?
Are you using rodi water?

 

[hyla84]

My Rodi is 0, even if I change 200 liter out of 400 liters no3 doesn't change.
I do feed my fish with pellet once a day a really small amount. I do have a Skimmer (bubble magus d8) I don't have a sand bed but rocks leaves a lot of sediment...

Sorry forgot to tag

Its your rock then.
You will have to decide what to do and how much work or money to put into it.

 

[vetteguy53081]

Not very serious numbers.
What is age of tank?

Continue to blow off rock frequently to remove the detritus which is probably the sediment you are referring too. Vacuum out the detritus. Over time there will be less and less and your nutrients will drop too most likely. Daily to start would be best and perform small water changes after vacuuming.
