Macro algae

[Perthegallon]

My macro algae has been slowing turing white and clear what is wrong?
The nitrates are at 3ppm
And phosphate at 0.02

Likely low on Iron and iodide. What type of lighting are you providing it?

Do you know what species of Macro algae it is or do you have a picture you could share?

It’s the sea lettuce

How long have you had this algae in your system? Was the algae growing and then stopped growing before it started turning white/clear? As it was suggested above it could be a nutrient deficiency if the algae has been established but suddenly started this behavior. When the algae has turned white/clear it will likely not come back and should be removed if its not green.

Increase light intensity and it needs flow which may be lacking in this container.

Light is perfect
Lack of nutrients is my guess. That stuff grows like weed in a grow house

+1.


0.02 is PO4 is really low (assuming you are not testing with the API nitrates and phosphate kits)

You may have bottomed out causing the die off. The die off might have led to a small uptick which you tested.

Leaning toward water parameters (low/missing trace elements). Or - Have you added any bacterial agents recently (Vibrant, Microbactor, Dr. Tim's, etc...)?

I have a lot nutrient system but I try to feed reef roids and other products about every other day to keep the corals healthy I stopped running my protein skimmer as well

Yes I should let my no4 build up I’m using a brand new nose test kit seems to be very accurate for the most part

I also feed the nem that bright well stuff

Yeah it’s really sucks it’s dying I haven’t done a water change in a week and half hopefully to build it up

The flow should be fine it’s at the location below the return chamber so any water from dt has to travel through the box to go into the rest of the sump the light seems to hurt it more so I’ve cut back on time and intensity

Just thinking out loud here...any chance your light is too close and you are bleaching out the algae. We use the same light, and have read that depending on your distance to the algae it can be quite intense.

The nutrient conversation that many have pointed out here makes a LOT of sense as well, but I wanted to throw the distance/intensity of light to the algae conversation into the mix. We notice faint bleaching to the top of our algae in the refuge while the rest of our chaeto grows extremely well. We rotate our chaeto daily to prevent "burns".

thats a good idea ill start doing that I also worried about the bleaching I've put it as high as possible
