PO4 and Aquaforest

[Flavio Carpi]

@Flavio Carpi are running filter socks? I pulled mine and the daitoms on the glass went away.

@jsker no, in my sump water reach the skimmer chamber (that I'm skimming wet), than Goes to this product

After goes to siporax, and goes to other chambers with siporax, and at the end, return pumps(1 eheim 1260, 1dct 12000)

Try pulling the floss for 4 to 5 days and see what happens.

@Gary Wilkinson @Perry @Anirban
@jsker Guys maybe is there something that i'm not seeing, today i tested the tank water and got the following results:
NO3 = 0 Salifert
PO4 = 0.06 and 0.08 (tested twice, due the incredible results)
ALk = 7
Ca = 400
What i did since my last post
monday:
Performed a water changed 70L (tank volume have 700L)
cleaned skimmer cup
changed the floss
dropped at the siporax area 7 drops of NP and Pro Bio S
Cleaned the Siporax, that went from this:




To this:




Thusday:

i was far away from my house, and just feed the fish.

Today:
Cleaned again the Skimmer cup + floss
Saw less brown algae into the front glass.

My only Sps are in this way:


but some lps seems not good:



What should I do?

 

[jsker]

Last question, how old is the system.

Last question, how old is the system.

@jsker 10month old

I would try some nitrate to see if it brings phosphates down first. If it doesn't go down any by the time you have had 1 or 2ppm Nitrates, just use gfo to get your phosphates lowered.
I am confused because you say you run gfo which should keep the tank at 0ppm phosphates but you alwYs have near .1 phosphates. If you change your gfo it should go down near or to 0ppm and if it doesn't your not using it right. You may have to keep refreshing it every few weeks if you have locked up phosphates for some reason.
I would not worry about colors so much, worry about health and growth then later colors will come.

@Pedoconfuego how is the correct way to use the GFO? im just using it at the TLF changing it at 4 weeks

 

[Graffiti Spot]

Use a Hanna checker to measure the output of the reactor, you can see when it stops absorbing phosphates and will give you a higher reading or will just read the same as your tank water.

 

[Flavio Carpi]

@Pedoconfuego i did it last week (tested the water in the out put of the reactor) today I will do all the test again and will share with you guy here

@jsker @Anirban, follow my result by today (its getting a crazy journey)

Friday tested the water at the LFS, all of them test by red sea:

KH: 7
PH: 8.4
Ca: 300 (incredible i've ested as i reported here 400 3 days before in salifert kit)
NOe: 0.25
PO4: 0.08
Mg: 1200

For my mistake, i've forgot to perform the cross check with my tests this day, and i just performed a new 70L WC with HW reefer salt.

i went away from my home during saturday, and came back on monday that i just eed my fishes (small amount)

Today, it was my plan to do the test, but i've focus in other thing and first, i've give food to the fishes with live brine shripe, after that i started to perform the test":

KH: 6.5 (Salifert)
PH: dont have for now (its coming)
Ca: 390 ( really strange due the last test @Salifert)
NO3: 0 @salifert
PO4: 0.33 it was my first test before to feed the fishes, after perform all the other test, tested again and the results are: 0.09 and 0.11) all of them with hanna checker 713. To know how my PO4 is going, performed the test into the output of the reactor, and i got 0.15 (its getting me crazy).
Mg: dont have the test, coming with PH as well.

Dont know what to do, keep dosing NP and Pro Bio S (7 drops at the siporax area), or stop and just see the reactor of the tank?

 

[jsker]

Run some GFO to bring down the Po4. We know there high. Your Mg should be 3 times your Ca, in both test they need to come up.

 

[Flavio Carpi]

@jsker yes I'm running a tlf 150 reactor with phosphate minus I changed the mídia 2 weeks ago

 

[Perry]

Be careful of reacting to Salifert test kits, I exploded my Calcium and Mag levels with test kits that were almost depleted, and still within date range. This becomes the norm about 3/4 use of their test kits. Please do not make adjustments until you confirm these numbers, Cheers!

 

[jsker]

I would average the LFS and your last number an make minor adjustments

 

[Flavio Carpi]

@jsker and @Perry which test should i use? i only can go to LFS on weekends =[ (their use red sea test kit)

Also due the picture that i post the bali and the leather that is not showing the polyps, seems that something wrong is happening with some parameter, which parameter could be?

i already have the products to fix the parameters, but waiting the conclusion here to start to dose (first is to fix MG and other is kalkwasser to bring up the alk to 7-8)

@jsker and @Perry which test should i use? i only can go to LFS on weekends =[ (their use red sea test kit)

I have been using Red Sea for the Po4 test, if they have it that is the one I would use.

 

[Flavio Carpi]

@jsker For PO4 i'm using hanna checker 713. i understood that i should use for the other parameters as Ca, Mg

Hanna Checker makes different Checker for different test. for example one has to purchase a checker and reagent for the Ca test.

 

[Flavio Carpi]

Hold on, guess we are talking different things here.

The tests that i've performed for PO4 it was with Hanna Checker. is it ok?

all other tests i have and i used a Salifert. which brand is better?

the LFS tested everything with Red Sea, the ones that they have for sale.

 

[Flavio Carpi]

before the tested below i just cleaned the glass that it was fully of brown algae (just past 2 days from the last day that i cleaned)


PO4 = tested twice 0.16 and 0.18 @ Hanna checker 713
Ca = 400 @ salifert
Mg = started dosing bailling, due the vendor recommendations i have to dose 333 ml per day to bring my Mg (1200) at the desired level
Kh = 6.7 @ Salifert
No3 = 0 @ Salifert

stopped to dose pro bio S and Np.

Any other recommendations?
