Default Burnt tips in acropora

Hello everyone
I have a problem with burnt tips.
Potassium stands at 390.
kh stands at 7.
I have a 720 liters.
The flow rate in zeolites is 700 liters per hour.
Does anyone know what the problem might be?

Difficult to say can you please post some more details ?

Have you recently increased the K+ level of your system ?

How much Zeovit material have you running and when do you exchange it last time ?

Which kind of carbon are you using, and how much do you have running ?
Do you have the carbon in some kind of a filter ?

Have you reduced the PO4 level to quick in the last couple of days ?

The string you have described are a sign of heavy stress for the corals. As we can rule out the known reasons for the issues my next guess are toxins or harmful substances leaching from any kind of equipment. Have you added any kind of equipment / material in the last couple of weeks ? Also check your pumps etc. for rust.

Shauli,
a picture of the display tank and your equipment's will be most helpful. better than leaving it to our imagination
also can you post details of your tank please:

actual water volume (tank+sump-rocks)
current parameters (NO3,PO4,Alk,CA,Mag,Salinity, K+..etc)
current dosing (alk,ca,mag,ZB,ZS,SP,ZF...etc)
zeolite dosing (rocks)+ reactor flow
tank bio load (fish+coral) or just post pictures
water change scheme
salt used

without details we cannot trouble shoot especially when done remotely.

thanks

To be honest,in the three years I've been working with Zeovit I had no success.
I had a lot of falls because of things I did.
Recently six months ago I decided to add aragonite.Since then I have nitrite at a level of 0.02,and nitrat 0.5.
During this period I lost a lot of coral.Some peeled off and some were burned.I've just lowered the intensity of the lighting maybe it will help.
I really want to get back on track...

Shauli..
no worries we will try to help you. the community here are very open to helping others.
looking at your parameters you are not that far from the ideal condition. I think small tweaks will go long way. the important thing here is to avoid quick changes and do not experiment too much at the same time.
one mistake reefs do (myself included) is to follow every single advice or method we read here and there. Zeovit is a very custom system that end up being build to your specific tank needs, there is almost no 2 systems that are exactly the same. so when you read something that someone did and worked for their system that does not mean it will work for your system 100%.
I also think your dosing is bit off, especially with SP, you might be over dosing SP.
I will also advice to remove the rocks in the final compartment in your sump, or clean them often, they will trap nutrients and end up generating NO3/PO4 to your system. yours main display rockwork is enough in my opinion.
now lets work on a plan for you:
-Zeolite 0.7l, water flow should be 190~200GPH. so increase your reactor flow more, this will help reduce your PO4/NO3
- change rocks every 4-6 weeks for now until you achieve stable UNLS. when you change, change 90% only and leave 10% of the old rocks in the reactor. also when you change the rocks do not take the reactor off and clean it, leave the water inside the reactor if possible, this will help re establish bacteria quickly when you change the rocks which is critical phase .
also when you change rocks, dose ZG for 10 consecutive days, then switch to 3 times a week (change to 2 times a week when your NO3/PO4 is low and stable)
- ZB 7 drops 3 times a week (if you feel you overdose reduce to 2 times a week, sign of overdosing is a brown film on water surface especially in the sump). try to dose when you shake the reactor
- ZS 0.7mlx2 a day. do morning and night. try to dose when you shake the reactor which should be 2 times a day you shake the rocks 10 times or so.
- SP 7 drops 3 times a week. dosing 0.7ml is high
- ZF is not really needed now, and will increase your NO3. so lets back it off to 1 time a week 7 drops
- get BM and ZZ. dose them as follow: mix 1 spoon of ZZ(included in the ZZ) with 0.5l of your water tank, choose a container that have a lid. mix ZZ well in the container then add BM (14 drops) mix well then close the lid and leave the mixture ferment for 8 hours. then dose it to your system. try to dose at night after lights off. this will break down some deposits and nutrients. do this 2 times a week
- dose CS 7ml 2 times a week (what I like doing is to dose the CS the morning after I dosed ZZ+BM at night). this way any nutrients that ZZ have broken down get bounded by the CS
- if you can dose CV and AA to aid your coral health. I would start with 3 times a week CV (7 drops) and 2 times a week AA (7 drops) and see how your coral react in term of PE and growth. we will add more coral elements later
- bring down your Alk slightly and make sure it do not fluctuate beyond 7~7.5. test alk Daily, and I mean Daily.
- bring down your CA to ~400. test weekly
- test K+ weekly and make sure its around ~400
- bump salinity to 35ppt if you can, this will help maintain your alk and CA at the levels described. be careful when you increase salinity your ALk/CA will increase. also make sure your salinity is indeed what you think it is. use reliable salinity meaning method that is calibrated. you will be surprised how many reefers have had problems just to discover that their reflectometer were off and their salinity is not what they think it is.
report your parameters and your system health often so we monitor with you.

over all you will need to correct the reactor flow and the SP dosing, the rest is tweaks. we will get you there just be patient.

Thank you very much for caring and help..
I'll do everything you've suggested and I'll update later....

Before that I have a few questions..
You wrote :Zeolite 0.7l, water flow should be 190~200GPH. I have 1.750l zeolits..
I believe you have referred to 1.750l...Right?
You wrote:dose ZG...you meant Zb?
About the Sp..I meant 7 drops,my mistake in writing.
About the ca...my ca is 426 ,is there any way to lower it?
Just to be sure, regarding salinity..i'm currently at 24 degrees,35 ppt Correct to this temperature?
I measure salinity with hydrometer Of Tropic Marin,and my salinity is 1.024.
How much salinity is 35 ppt in a hydrometer?

Shauli...

Hi Shauli,
sorry for the typos, I was writing too fast.
yes I meant 1.7l for the zeolites
yes ZG meant to be ZB
good for the SP, 7 drops is what you need.
over all for your water volume (~200G) you will need 7~8 drops of dosing for any product that is a drop per 25G..
CA and ALk will go down by itself if you do not dose additives, the coral will consume it. it will also be indication that your coral is growing. but make sure you do not drop below the recommended values.
for salinity, 35ppt means 1.026. I like to keep my salinity at 1.026~1.025...this is not super critical as long as you keep the same value all the time. I have seen many reefers fluctuate this value when they do water change because their measurement method is not accurate. I have not used your reflectometer, I use red sea and an electronic reflectometer for cross correlation. these reflectometers need calibration regular, you should calibrate based on what they recommend (RODI water) then cross correlate with a 35ppt calibration solution, you will be surprised how much error you might find when you use a calibration solution reference (35ppt) if your reflectometer is correctly calibrated, a 35ppt reference solution should read 35ppt (1.026SG) exactly. this is the ref solution I use
https://www.amazon.com/Standard-Seaw.../dp/B0053DSWJA
one last thing, if we do not see reduction in your NO3/PO4 over the coming couple of weeks, we might want to increase the zeolites to 1.9l since your water volume is ~190G but lets do things slowly.
