IM screen PAR loss?

[speedstar]

Anyone have numbers on how much the screen diffuser on innovative marine tanks changed PAR value?

Thanks

I think brs did a test with different screens and it was negligible. I can’t seem to find it though.

The older IM screens are bad, I'm planning to replace mine

Any picture to tell the difference between old/new?

The old ones were a very thick mesh.
I replaced the netting in mine w BRS mesh.

BRS did a video on the screens effects on lighting and it was negligible.

The older model used really think screen with small openings, these were the pre built ones, now IM is selling DYI that use the screen that BRS sells

Thanks mine is the older 1/8th thick stuff that seems to act as a diffuser as well.

Whichever one BRS tested, it only reduced about 4-5%.

I tested my screen with an apogee 510 and didn't see any noticeable difference. I'm using 1/4" clear netting from BRS.
