Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
I bought an anenome and a clown that was already hosting it together at Aquatic Obsessions. They even went home in the same bag because the clown would not leave the anenome.
I have baffles to elimate it but I never got rid of them all until I put a filter bad on top of them. I think that helps the best. I am just really good about keeping it clean.
I personally found that 50% on both seems to make everything happy until you acclimate them to the new light. (not sure about the alk)
I set mine to 50% and raised 5% each week until getting up to 100%.
How recently???? If they are getting used to the light they will not be happy for a while. Mine took a while to adjust to things and you have to be carefull to make sure they don't start to die on you.
I would change the settings to 50% on both blue and white and see the results.
I only have a dozen or so Mexican turbos in my 240. I think the type makes a big difference. It has been up almost over a year and never had a problem with these guys. They do a great job.
