Check Your EXPIRY DATES
in a post i had earlier COPPER IN MY DISPLAY TANK i thought i had put copper in to my main tank.
Thankfully i don't think it was copper. Maybe i just jumped to a conclusion to quickly..
I did have that silly block off valve in place but the inside was actually stainless steel but coated with an oxidization giving it a brown look. Any way its gone now. AND things had not improved much with the cuprisorb product that is meant to change to blue when a copper trace is found, which made me think deeper. My water conditions are generally great, i would almost say perfect, and because of this have held off doing any water changes out of experiment, i no stupid in itself but I took a water sample to the LFS and asked them to do a complete check of everything they could, even SG with their API test kits.
NITRATE on them is yellow 0-10ppm and i think Red 80-100ppm plus
MINE WAS REDDER THAN BLOOD. I was shocked and asked him to do the same test again.
SAME RESULTS. I took this exact water home, with a new kit SAME BRAND and tested it again at home. Old chems PERFECT READING new chems REAL BAD. It was the water parameters that where killing everything off, who noes what was next.
Now i no why there IS EXPIRY DATES ON THINGS.
every second day 20% water changes for a month and everything is coming back great. Now i make sure water changes happen at 10% every week without fail.
