Hello~I was wondering if it would be okay to use 1 year old stress coat that has been exposed to heat (garage). I have a 30 gallon tank that is a fresh setup. The fish are good start up fish and I was told very resilient. I ran the tank for 4 days before adding fish. I added aquasafe at start up. They are very active and eating well. They have been in about a week and I am noticing some fin damage. I am running an eheim canister filter, water temp is 80ish I am not sure of ph. I have a #1-#2 hagen test kit, I don't know if it's nitrite or nitrate but when I conducted the test the water turned lavender (light)
Thanks~Marley
