I had lettuce nudibranches, and urchins work for me. If your running a calcium reactor with a media similar to the ARM brand you may be releasing phosphates into your system that way.

Not meaning to hijack the thread. Can you run a bag of phosban or similar in the back chambers and receive any benefit? Just curious have a bit of a GHA problem myself.

Thanks

In the back chambers of what? Maybe I missed something. But running it passively would have some benefit, sure...

Sorry Drew,
I'm running a 24 gallon nano cube with three chambers in back. Thanks for the info. Will give it a try next time I make an order.

I got a sea hair on the weekend and he just about eat him self to death.

The PO4 was coming from the frozzen food. I'm back to working dayshift instead of afternoon. I didn't know to rinse the food. I was putting one cube in a cup with salt water to thaw then feeding half in the morring and half before work. I was only feed frozzen every second day. The tank could handle that but not every day. One more learning experiment by trial and airer.:biggrin:
Thank for the input and helping me solve my problem.
