Tank not looking too good ?

[MrDLHughesY]

Hi guys Over the last week or so my tank has started to look abit worse for ware. I have also just recently got an outbreak of cyano I had a swing in alk which dropped to 6.7 which I have since raised back up to 8.1 slowly. Possibly this could be why my Zoas won’t open and my BTA has gone hiding, most my coral isn’t opening like normal. I also recently increased my lighting schedule which I have since changed back to normal due to my current problem. Also my po3 dropped to 0 from 0.3 which is why I may be battling cyano. Anyways here are my current readings.

Salinity - 1.026
PH - 8.2
Nitrate - 2ppm
Phos - 0
Alk - 8.1
Cal - 430
Mag - 1280
Temp - 76

Started to feed a little more often to try to raise My nutrient.

Any ideas from you guys on what could be causing this thanks

Start with 10% weekly water changes. Are you using rodi?

 

[MrDLHughesY]

I use rodi to top off and pre mixed from the lfs as a family member owns 1. That is my current schedule atm 10% every week so might up it abit whilst I battle this

They may need to change their rodi filters.
