check your parameters in your RODI system. That seemed to be my problem when i had hair algae issue, noticed a difference right away. Got a Abalone snail and Tiger Cowrie and they cleaned up rather quickly.
Nice set-up... Will be setting up the same tank (rimless) when my skimmer and lights get here!... hopefully this weekend... Aquascape came out real nice
Can anyone identify this? and it doesn't look like coralline
Not my tank but the tank we have at work... The company that handles this tank is not very good at it and I am sure they charge my midtown firm plenty of money to maintain it!!!!
