Causes of coral death

[aziz]

Hello, my corals are not growing well and their colors are not good. After a few weeks, the coral dies. What is the reason?

Coral require good water circulation, good lighting, and water quality and good nutrition. Something must not be good if it is dying so quickly.

.Hello everyone, my lighting is Red Sea LED90 and I use Tropic Marin Pro-Reef Sea salt and the water current is good but the alkaline, calcium and magnesium levels are higher than the recommended limit.

But I only test chemistry for alkali, calcium, magnesium, nitrate and phosphate. Is there anything else I can test?

Sorry but to help you we need to know all the info about the tank to help you..... Can you advise all the water parameters, lighting intensity and duration, type of flow, tank inhabitants, really need pictures too, of the tank and of the corals. Give as much information as possible.

Pictures of your tank would be helpful as well!

Hello, my corals are not growing well and their colors are not good. After a few weeks, the coral dies. What is the reason?

My grandfather used to say when asked a very vague question, "want the whole list, or the top 10?".

Please, list;

Tank
Parameters
Lights
Par or settings
Filtration
Maintenance schedule
Stocking, ie: fish, inverts, ect
Problems your seeing

Pics, we love pics. White light only as we cannot see with blue lights on this forum.

Thanks and welcome to R2R!

alkaline, calcium and magnesium levels are higher than the recommended limit.

BTW, this may look like a smoking gun or maybe not.

Hello everyone I would like to thank you all for your help

I tested the water today alkalinity 10.5
calcium 470
magnesium 350

nitrate 0.05
phosphate 0.03 and my lights are on from 11:00 and off at 22:00

I maintain the aquarium every week by cleaning the filter and changing the water 10%100. I use Tropic Marin Pro-Reef Sea salt.

I only use chemistry to reduce the percentage of nitrates and phosphates, and I do not use anything else.

I consider that high alk and with low nutrients is a bad combo.

But, this looks like a new tank so forget that for now.

By the looks of the water surface, you need more flow. Looks like you have 1 wave maker and the return. Is the wavemaker adjustable? Can you turn it up?

Do you know the par from the lights? What light is it?

 

[aziz]

My lights are from Red Sea Reef LED 90

 

[Dburr1014]

Pretty sure you may need to turn them up.

 

[aziz]

I'm sorry I didn't understand what you mean I should turn it on

 

[Spare time]

0 nitrate is a problem. Raise the nitrate and make sure phosphate doesn't hit 0.02ppm or lower.

 

[aziz]

My lights are working at 50% blue 20% white is this ok or should I increase the light percentage

Is mag 350 or 1350? cause I don't think I've ever seen mag that low. Nirates and phosphates is nutrients for the coral, try to get nitrate to 5-15 ppm but i think phos is fine.

Some of your corals appear to be stretching towards the light, so turn up the intensity of the light, 50% is too low. But do it slowly, maybe 5%-10% per week for a few weeks.
