You said that your LFS said your parameters were 'OK'. Did you write down what they all were? Do you know what your Phosphates are at?

I would continue to do waterchanges, stop adding chemicals, and see if you can get ahold of a diatom filter like Vicki mentioned.



Just on a side note, brine shrimp is slim to none for nutrition for your fish, I would change up their diet a little. And feed less too, I only feed every 3 days, I learned in the beginning that feeding daily leads to lots of algae breakouts.
