Greetings from vietnam

[mushromboy]

Hello guys sorry for my grammar

I'm a Vietnamese Hobbyist and i have a small All in one tank mainly keeping softies and some LPS that are running for 2 years and i'm still struggle to make things right .My reef has thriving time but now things kinda bad
So for that reason i'm seeking the knowledge that can help me find my tank beautiful again
Thanks for reading this
P/s : my current parameter is
Cal 440
Mg 1050
Dkh 13
No3 50
No4 200( test with hanna checker that have ppb and the digits are blinking)
I'm reduce my noopsy k7mini to 25-30% and running for 12 hours
LFS said that i'm might have heavy metal issue or the micros like pottasium iodine when rouge so i'm running redsea active carbon and some DIY indoor reactor with biopellet and little bit of GFO
Here it's my tank picture appreciate anything could help
Thanks you guys

These stand out to me:

Dkh 13 - Try to lower slowly. Somewhere in the 8-9 range would be good.
No3 50 - Try to lower slowly.
No4 200( test with hanna checker that have ppb and the digits are blinking) - I think you mean PO4 and again try to get that lowered to an acceptable range.

Welcome! Is there a specific reason your alkalinity is so high? If not, I’d consider lowering it slowly to around 9 dkh. Also, I’d consider lowering the nitrates and phosphates.

greetings! Looking good!

Welcome!

dkh that high is likely to be the culprit? What saltwater mix do you use? What’s your salinity?

Welcome to R2R! I agree with @SPS2020, @Reefer Matt and @crazyfishmom, I would start by slowly bringing down the Alkalinity. Once you get it down to below 11 (with your coral mix somewhere around 9 would be a good end goal). Figure out why your Nitrate and Phosphate are so high, usually from overfeeding and try to reduce them as well. Your tank doesn't really look like the Nitrates and Phosphates are that high though. Have you verified your test results with an LFS?
