Help!!!!

[Dave Waits]

I would suggest one thing right off the bat, rehome the Goldfish. Goldfish with Tropicals in the same is problems waiting to happen. Goldfish produce a lot of urea(Pee) and this is very unhealthy for the Tropicals, especially the Angelfish.

Ok; did a 75% water change in my 30 gallon because had another angel pass.

Strip test: (ordering other)
NO3 20
NO 2 0
Ph 6.5-7.0
Alk 0- 80
Th 0

Tested 20 gallon with bristle nose pleco
NO3 160
NO2 0
Ph 6-6.5
Alk 0
Th 0

Please post a link to what all these parameters mean... Should I move the gold fish betta and tetras to 20 temporarily until Ivan figure something out?
