First of all let me explain as clearly as possible so that I can get help...I'm new and unexperienced and need your help getting established....So I'm counting on you guys!
I had a 37 gallon tank that has had 6 African cichlids in it for nearly 6 months - now re-homed . Did a 50% water change after getting rid of fish but didn't change the filters, just cleaned them in tank water.
On the same day of trade I got a 2 1/2" BP and 4 small serpea tetra and put them in the 37g.
Six days later I got 4 more serpea tetra and 2 small angelfish the same size as the BP. All doing great together.
Exactly one week later I did a 30% water change but didn't test water. I always add Prime to new water though.
Now it's coming up to the second week's water change and I noticed my BP has some stress spots but he is acting normal so I did a water check......this is what I got (and need help understanding)
API 5 in 1 Test Strips: Nitrates = 0, Nitrites= 0, pH= 6- 6.5, KH=80 (pale green), and GH=180 (purple/blue)
I did put in 1 tsp baking soda and added a piece of driftwood and a few shells. Should this help? I think the later 2 are off. What should I do to correct the readings. Should I be concerned? And when should I test again?
I'm confused on what the readings should be now that I added the angels. I don't want my fish to suffer because of my inexperience.
Oh, and my water temperature is a constant 82F and I am planning on upgrading to a 65g very soon.
