Thanks to all for your suggestions.
im still trying to ‘stabilize my tank.
last night I tested the water
ph-6, ammonia 0-.25, nitrite 0 nitrate 20-30
then I did 25% water change, cleaned algae off decor and sides,
also added more of my sand substrate that I rinsed well first.
have gotten rid of the dying plants and no dead fish hiding.
added new red root floaters.
this morning tested again.
ph-6, ammonia 0👍🏽, nitrite 0, nitrate 5-10.
my concern is the ph is pretty low. Should I add a couple sand dollars to the tank ?
My Cory’s fins are bad but I was still waiting on the meds. To see how water changes went…
I definitely need a whole new clean up crew!
I appreciate you guys’ experience and getting back to me, Annie
