Answer 1

i don't know if i'm to late... i'm really sorry about your guppies. i'm not an expert, but you mentioned that you do plenty of water changes. do you use tap water? because if you do, it is possible there are too many minerals in the water...try using bottled water in the tank. i don't know if this will help, i really hope it does.

Good luck.

Answer 2

Check your tap water for ammonia and nitrite-- these are very toxic to fish, and are fairly common in tap water.  Also, contact your water company and ask for a print out of the chemicals in the tap water in their respective concentrations (preferably parts per million AKA mg/L), as many municipalities add metals (copper, iron, lead) or nitrogen compounds (ammonia, nitrite, nitrate, chloramine) that can kill fish.  Using a dechlorinator like Amquel+ or Prime that neutralize heavy metals, chlorine, ammonia, nitrite, and nitrate would be a very good idea, as this will protect the fish while not interfering with the biofilter.
