High po4

[solo_reef]

hello reefer i start zeovit system start 27/1/2020

po4 : 0.592 ppm with HANNA

NH3/NH4 : zero

NO2 : 0.2 ppm

NO3 :25 ppm

My stock
1 rabbit fish 8/2/2020 size 4 inch

1 zebra drat fish 8/2/2020 size small

2 maron 17/2/2020 size small

2 clown 25/2/2020 size small

1 triger 16/3/2020 size 2 inch

2 tang 26/3/2020 size 2 inch

4 pajama 15/4 size small

i feed two time frozen food and pellets

I make 3 big water change in one week and still the po4 high 165 ppm any idea ?

Are you able to test another water? Like your LFS, maybe your tester is no good? And is that the Hanna phosphorus checker like this ?

i have 3 tank and only this tank po4 is so high yes the same one

And that’s after the conversion? Multiply ppb phosphorus by 3.066 then divide by 1000 to equal ppm phosphate?

Toe phosphorus is 195ppb?

 

[solo_reef]

Yeah i have the sheet

You also have elevated Nitrate.
Have they both been high from the start?
Try a 50% water change and see if that helps.

 

[solo_reef]

No they increase slowly i did 3 WC 30% in 10 days also its high im thinking to lower the feeding ;/

Are you having any problems with the tank?
If you want to lower PO4 you can use GFO or Lanthanum, water changes aren’t the best way.

No only fish in the tank but im afraid high po4 can harm the fish. I cant use GFO im using zeovit system.

I wouldn’t worry about PO4 and N in a fish only system. 0.6ppm isn’t that bad even with corals.

Do you plan to add corals?Is that why you started zeovit?

 

[solo_reef]

Yes i want to add coral but im waiting the systeam to be stable

You dont have levels that will harm fish.
You do have levels that will grow algae.
Something is a miss. Over feeding or over dosing some of the zevo stuff.
There is not enought of the zevo bacteria to process the nutrients.
Do you vac your sand? Maybe a build up of ditritus.

 

[lapin]

Oh and welcome

Maybe last two week i over feeding 3 time a day,and everyday frozen food. Yes i vac my sand weekly with WC. Zeovit dosing exactly following the recommendation.thanks alot

Do you have a sump? Maybe you can try cheato to deplete the system of nitrates and phosphates!? I feed my tank once a day, I use NLS pellet food and at times frozen. 3x a day might be over doing it.

I have been and am fighting high phosphate. Water changes will only lower it right after. It will be back up in a couple of days. Try phosphate rx and mb7.

 

[lpsouth1978]

I am a bit surprised no one has asked this yet, but what size tank is this?

 

[SPR1968]

I’m not sure why you can’t run GFO with the zeovit system, especially if it isn’t working for you, but you need to have some export method in the tank for both phosphate and nitrate control if what you have can’t keep up. Water changes will help with nitrates but less so phosphate

At 0.6ppm phosphate that’s very high and even though your fish only, your likely to have algae and other unwanted issues if you haven’t already. A good target is 0.03ppm so very low.

If the level has been raised for some time, it’s likely been tied up in the rock work so when your changing water is probably leaching back out and will continue to do so.

Personally I use rowaphos (GFO) in both my systems and I keep phosphate locked down very low at 0.03 or less and have zero issues and it also makes the tanks look ‘clean’

If you go down this route, you will need to change the GFO regularly to start as it will become spent quickly as the excess phosphate is released from rocks etc. if you don’t it won’t work.

Your right but what we must understand first where is the problem so i can solve it. Does the rock keep leaching po4 for a long time ?
