[Born2beblack]

Okay so my tanks 5 months old 30 gallon plus 2 month cycle

Peremeters
Salinity - 1.025
Temp - -_-
pH - 8.3
Alkalinity - 13.5
Ammonia - 0
Nitrite - 0
Nitrate - 35ppm
Calcium - 400ppm
Magnesium - 1400
Phosphate - know test yet
Peremeters have been steady and no upset corals till this

Tank mates
2 clownfish
1 bi colored blenny
1 blue damsel
6 hermits
1 conch
1 sand sifting starfish

Okay so i just resently notice my temp went up by 10 degrees -_- so yea would that be the reason my duncan coral has looked off the last couple weeks.
I know my alk is high but ive been trying to get it down slowly cause i dont wanan just bottom it. Anyways what do yall think. Need some help
Tanks been running fine other then that bump
Also the duncan coral has been open every day and taking food its just lost its color. I have also moved it further down from my lights. Ive had new growth as well so

Coral is closed cause that's 5 mins after moving it
I did do a panick hand dip -_- but i just really dont wanna lose it i do enjoy it.
Open to all suggestions as im a scrub and need help

I have never seen a bleached duncan before.

Get your temp stable below 83F and slowly lower alkalinity and ths coral may regain its zooxanthellae.

 

[GabeM]

Oh and keep feeding it as it will need it while bleached

Hello fellow reefer,

10 degrees !!! Everything should be dead so yeah that could be the reason.
You say a couple weeks what's the temp of the tank now? and what did it spike to?
What temp do you maintain the tank? And what is your method of temp control?

Your alk is also high and trates and calcium low but i would focus on keeping that temp in check first and foremost

 

[Born2beblack]

Okay thanks boss ill keep feeding it. Ill try to lower it any suggestions for that, that could help?

Water changes will help - what salt are you using?

Mytenp went to 88
Im suprised my birds nest isnt the issue
Im pretty sure my cousin turnes the nob when i had her over looking at the tank -_-
Idk didnt matter its went that way for a week and half
I have a temp gauge on the side nothing special yet.

Oh no sorry to hear that tell People to keep there hands off your tank!
Temp controller is very important in this hobby and is a wise investment, can get one for comparable money to some of the frags your gonna be buying yourself soon im sure.

Good luck

Also how quickly did you add everything? A 5 month old tank sounds like you got a lot quickly. You might not have given yourself enough time to cycle. What other cord do you have in the tank? What is your lighting and water flow like mine like med-low flow and med light using a kessil a360w

My tank cycled for 2 month and i tested stuff and no ammonia or nitirtes so iwent with clowns and some CUC
Resently added the 2 new fish

Now coral has been one every week or so
I didnt know how much or little.so just been cruising i have a wave maker, sump pump and for some reason when i started i put a 30g in tank filters which i need to rip out.

Idk my light its to cheaper lights but my birds nest is one of my older corals and grown so much so i assume the two lights do good
