Polyp extension in plumbed together tanks

[cilyjr]

Granted one tank etc… Done it few times same outcome.
Could be light related, not enough/too much

How quickly did you see this?

How quickly did you see this?

It is about 3 months between the pictures. I was reducing the intensity by 5% a month and observing etc…

Few years back I had fuzzy SPS:

And I had crash, went on vacation and the tank turned freshwater/brackish water.
Had bit of a reboot and for what ever the reason I had none to minimal polyp extension.

Out of all the levers I tried the light intensity is helping the most. I knew I increased the intensity at one point but I didn’t think 10-15% could make such a difference.

Good luck,

This is an almost zero risk experiment.
I will drop it some and report back...

I decided to buy a par meter. I went with the one that Neptune systems sells as it will integrate into that system.

Not sure how integration works or is all that beneficial. Test your par once and you are good to go sans re-scaping. Test once per year to monitor LED life. I can't wait to see your results!

This unit is always attached to the apex

The par meter that I wanted was on back order. I did borrow one and from the results, I'm going to say that it pretty clearly was not a too much light issue.
So I'm back to how they were a month ago.
Par readings for 8 x hydra32hd and 4x 4 foot t5 are as follows.
Top left 300
Top mid 465
Top right 350
Mid left 160
Mid mid 225
Mid right 170
Bottom left 130
Bottom mid 185
Bottom right 150
