My water parameters are actually really great and my tank has been up and running for several months. I can easily house some SAE in the tank without problem, the Amano Shrimp are hard to come by around here, I've only been able to find them acouple of times and they were gone before I was able to purchase them.
I'm actually using Flourish to feed my plants, upping the dose will cause it to die? I've read that it can cause stress on fish if you up the dose, is this true? Also, how much should be used per gallon per day?
If you can use a syringe to directly treat the algae with Excel. You should keep an eye in your nitrates as it can increase them.
