But there are some corals on the rocks. How much peroxide they will stand ?

I of course am very happy that nobody has (had) this bad pest in their tanks.
Alone in the battlefield (not so happy).

Youp

Update here. And new problem too.

All algae is gone by the time (good news) , except one (bad news). The one left is "Caulerpa verticillata" and I have no idea how to kill it. Actually it is...

I am using salifert kit too.
This K solution isnt concentrated but isnt expensive as well.

P.S. tested for stray voltage at...

The only device comes to my mind that is acting randomly is heater, and I tested it.
Potassium is tested and replenished. WC would not hurt at least.

Measured water to ground.

DC =0
AC = 0.1-0.2 V. If I touch tank glass with a finger voltage jumps to 0.7V

Does it means something ?

Edit: After some more reading , I thing what I am...

How to test it ?

Found mine at 360, when I tested for first time. Now have it at 390.

Blue with white spots

Green acro single spot in the middle. As you can see birdsnest also has bad PE

MINION,

Thanks for such in detail article !
I only dose what is in deficiency, and I only dose after testing. I dont thing there is a case of overdosing .
Only acroporas are affected...

Actually I never struggled to keep nutrients low as I run ATS from day 1 !

Thanks - useful information.

kh=9.8

how can I find it ?

Good things never last long.
My SPS corals started to STN. No idea why. Can it be too low P and N ?

Eaters came a bit late - after algae started decline rapidly. Better late than never.

Suddenly algae in my display started to die rapidly. And at the moment it is may be 25% left only. Filter floss is collecting loads of greenish brown stuff everyday. I bought tomini tang and black...

M I N I O N ,

Thanks a lot for your explanations. I found it very useful . Many more reef keepers will read it and will educate. All that ideas and unanswered questions were floating in air for...

:D

Last few days I see some improvement, if onlt its not my wishful thinking,
Algae decreased on the gravel and some rocks are showing bald spots too.
What I did last days :
1. Dosed more trace...

Ok , I will .

Would be interesting what theory I will be trying to examine this way ?

I understand where you go . But how it can be p=0.00 , when my sponge (rocks) cant take P anymore ? It should have been rocketed to the milky way. But no - it droped from 0.02 to 0.00. You...

1. I am ready to agree with any theory that helps solve or avoid problem . I use RO/DI water. My fish and corals are starved to death, because I feed them only 1/4 what they able to eat in hopes to...

I am afraid to have opposite situation. I need more control over ammonia and less for N+P .

Measured total ammonia today using Salifert test and found it at 0.3
Is it very bad ?
Randy Holmes...

There I see two scenarios.
1. Vinegar destroys algae food and it stops growing. But that is why we keep it in first place - remove nutrients and not to farm algae.
2. Vinegar interacts with some...

What are vinegar dosing guidelines ?

Randys take on subject :

I would vote for this theory day and night.

What best way to control ammonia ?
Possibly two dead snails caused ammonia spike and started all that carousel . On the other hand ammonia spike...

Screen growth very well coresponds P measurings.

P= 0.04 screen grow nicely
P= 0.02 screen grow somehow
P= 0.00 screen grows alien algae, or stops growing at all. (Today's situation)...

I did not move even a piece of sand in tank when all this happened. The worst thing what comes to my head is that my son during my wacation could forget to feed fish several days and then dump 2 or...

Just rechecked to be sure :

No3 - 1.5 Salifert (good for SPS)
Po4 - 0.00 Hanna (deadly for SPS)

Hope so . But last 4 month picture is not changing whatever I do. Corals already starved to death. :( Dont know how long they able to stand that state anymore... Algae already started to attack...

My scrubber was able to keep
n=4
p=0.02
at all times
Would not call it week.

I clean glass once per week.
But how it can be phos in rocks ? Tank was clean and in a week something happened and now P leaching for 5 month ???

It sits after ATS and before return pump. I am sumpless. All toys in back chamber


666 is gone now :)

Story began 5 month ago. After returning from one week vacation out of town I found big bloom of algae in dt. Some macro algae also appeared from nowhere and "feeling good". My son told that all...
