Prime to Hydra 26 upgrade

[jpryce719]

Hello I have a 75 gallon tank, it’s 48” wide, 18”deep. We went from two AI Prime 16HD’s to two Hydra 26’s. Our Acan’s were loving the primes but the Hydra’s are blasting them with too much light. My question is; without using a parmeter, can someone tell meybe in a screenshot of myAI, what my lighting levels should be? I just use presets of David Saxby ( I did acclimate them)

thanks

You really need a PAR measurement to figure out where your actual light levels are. It's impossible to tell just by looking at the tank.

You need a par meter to know what your levels should be. Otherwise you're just guessing.

Thanks, you’re right. We’re going to rent one
