Bleached tips????????????????!!!!!!!!!!!

[KLR]

I have no clue why but all...All of my acros have bleached tips...some cases worse than others...~some tips are dieing and growing algae, some are just bleached~

Params are
0 ammonia
0 Nitrates
0 Nitrites
8 PH
420 Calcium
0 Phosphates
1.025 salinity


Lighting is 6 bulb T5 HO fix
4 ati blue +
1 geisman aquablue plus 15k daylight
1 UV Red Sun

Why is this happening?

 

[jaytizzle]

What's you alk, cal, and mag levels?

 

[clowns101]

He has Ca up there,but we need mag,and alk to be 100% sure.

 

[m and m]

Ima say it's your alk.

 

[KLR]

Calcium-420
Alk-5
Mg-1600

 

[clowns101]

Its your alk if its 5.

 

[KLR]

Ok well what should the alk be?

 

[m and m]

Yea surpassed things went dead bring it up slow don't want to shock things.

 

[clowns101]

Alk shoudl be around 8-9 at its best.Corals cant change more than 1-2 points of alk a day,and acropora being a very picky coral will not like 5 at all,that is very bad.

What scale are you measuring alk on,Dkh scale or what?

 

[m and m]

I would double check alk that's low for others to be high 9-11 is norm

 

[KLR]

Ok ill go re-test

 

[clowns101]

I keep mine at 8-9 so that it will allow for fluction in a safe zone,it generally stays at 9 so it can fluctuate at least 1 point and I will be safe.

 

[KLR]

I just found out it is even crappier than the 1st test.....................

Total alk-4
Borate alk-2
Carbonate alk-2

no wonder.......................so what should i dose to slowly raise this?

 

[clowns101]

Is that even possible?If your alk is that low,I would think every thing would be dead,no offence,I thin k you probably have a bad test kit,how old it is?Alk test kits dont last as long as other do.

Are you measuring meq/l alk or DKH?

[KLR]

This test tests meq/l alk.....and i just realized how much of an idiot i am:beat_shot:

Your test kit might be bad. I've had my alk down to about 5 before when corals were growing like crazy and my calcium reactor couldn't keep up to it. I target my alk around 7 dkh (natural seawater). Main thing with sps is try to keep thing consistent and not fluctuating and more importantly BALANCED. You calcium should be more around 300 if your alk is that low... Try to keep them proportionately balanced.

 

[ksc]

So just multiply by 2.8 to get your DKH. 4 meq/l x 2.8= 11.2 DKH, not bad but a little high. Just let it come down a bit on it's own.

 

[KLR]

Ok so would all of the acros be upset for being a little off or do you think it is something else?

 

[JOSE CASAS]

It is your alk, let it come down slowly. Do you know if it went up fast, the alk of course lol
