How will it affect the color of SPS if p04 = 0

[keigo]

Hi Guy,

We all know high p04 will have brown sps but what about p04 free?

I have been wondering because my tank have been p04 free.. base on hanna result show zero. How will it affect the color of sps???

Will sps color up faster or go dull instead??

So any ppls got idea or read some where..???

I also wonder about this....

and one more thing...

Why zeo people were interested in only PO4 not NO3?

NO3 is important to coloration as PO4. but In here people talk about PO4 only...

well because n03 and p04 most of the time r in ratio...
so in zeovit if p04 is been reduce, so will be n03...

But I'm more interested to know what factor in to color.. cause we know p04 play a major part.. but how fast will sps color up even in p04 zero water...

or p04 zero will wash out all the color instead...

Keigo, can you tell us what's been your experience in SPS color as your Hanna readings decreased? Have your corals become more or less colorful? As is always the case, nutrient level is only one factor in color. Current-flow, lighting intensity, proper parameters, & it's stability, & water composition[ionic balance & availabilty of traces] all play a role in coral coloration. Thnx. Bob

well bob, I have a gd enough water flow, ligthing intensity and proper parameters and everything stable...
and with LA3 mini and 3 x 250W PFO 6.5kk saki, I'm now only running 7hrs a day.

But as I'm starting to stay at p04 zero range.. I see that my sps some do get a bit brown out.. well I may be wrong.. but it seem to brown up a bit.. which I wonder also... but overall of the other sps are still in gd condition... and very slowly showing their color out..

and I do have a total bleach out sps.. which is near pure white with very light tint of blue....

also I have some old brown out sps which is still remaining at brown..

but with p04 at that low range i expect it to show color of what we see in the photo.. those super nice color.. but this is not what I'm having now...

so I wonder given low p04 how fast it aid sps to color up? Or maybe it will still take alot longer time to have all sps to color up very nicely.

Me also having all nutrients at zero. But my SPS colurs are getting light. Colour fades away i mean. How do i get their original colour back? My tank is just a 2 footer and a six line and anemone crab live in it. Pls help, keigo sorry for using ur thread.

It's ok kamiru.. we are all here to learn and share what we encounted.

Dosing AAHC can help darken the coral a bit...

When PO4 was undetectable (hanna) my acros colors got very light or so-called pastel.

What I did was to keep my tank less clean and feed more and from undetectable PO4 (hanna), the PO4 (hanna) now stays at 0.01. With high dosage of AAHC (8drops/day), PSG (12drops/day 14days in a row once a month) The colors of my acros are brighter and more intense now. PIF is dosed at 6drops/day. No overdose signs are observed.

My zeovit reactor is run 24/7 now as well.

Since upgrading to 3x250W BLV10kk + Luminarc, I've reduced the lighting hrs to 6hrs/day.

coloration is intense for all SPS except that are at the sides (which did not get sufficients lights with my old HQI reflectors).

I had 2 chocolate brown frags of digitata and both returned to original coloration in about 3 weeks.

Kamiru, you might like to post your dosages and tank parameters in details.

I guess what Bob said about stability makes a lot of sense, since retunning my CR properly, my kH has remained stable 7.4-7.7 and SG is monitored carefully at 1.026. All these helps.

keigo, are u from SRC? I saw the same topic under the sps section today.

Hi all,

my dosage are as follows:

1 drop zeofood/bak alternate days(for first 2 weeks of zeovit changeout, 2 times per week after first 2 weeks)
start1 at 1ml per day
AAHC at alternate days
PIF/Iron at 2 times per week

no3 = 0
po4 = 0
nh3 = 0
n02 = 0
ph = 8.37( running CR )
but having algae in main tank(why is that so?)

[gqjeff]

How many total gallons is your system? How many drops of PIF and AAHC?

[kamiru]

total gallons = 35
1 drop each for the supplements(sorry, forgot to include that)

I would cut the start2 down by half and see how the tank reacts after a couple weeks.. If the PO4 raises then you could raise the dose.. ALso I would add 1-2 drops daily of AAHC and PIF. I owuld also only dose Iron 1 time a week at 1 drop.. I have found that to add in algae production... Also what is the age of the tank?

time would be 5 months.
