Stumped!!

[mrjohnreed]

I began dosing the Nyos Ion-B in my 2 reef tanks. My 75 gallon is perfectly fine. My 90 gallon however is a different story. The tank is hazy and I have some type of algae growing throughout the tank. My parameters are as follows:
PH- 8
KH- 16dkh
Nitrate- 5ppm
Phosphate- .25ppm
Calcium- 450ppm

I have attached some pictures but they may not be the best. Any and all help.is appreciated.

That high dkh will increase the likelihood of precipitation- which may be the source of the haziness? Not sure how it would impact algae?

Since Im dosing my 75 gallon tank with the same product then im gonna check that tanks DKH to see where it's at because that tank is doing fine. Albeit it has a bit more coral in it and has a skimmer on it and the 90 doesn't. So we shall see and report back. Thank you.

You already got an answer, but you might want to consider uploading photos under white light as the blue makes it difficult to identify what's growing in your tank.

Side note: Have you made sure that shipwreck is actually reef-safe? Decoration often contain substances that you don't want to be leaching into your tank.
