Ya, when you can, a.s.a.p. get a teser you can read.. you need it.
when the tank finishes cycling, you wont have as much trouble, but you really need now that the air problem is fixed, to keep testig the water to make sure its in range.
As you already said and now earthstudent said, that 125 will not work for all three rays, for now you are ok, but in time, they will out grow that tank. Just be aware that that many rays in that small of a tnk will cause more polution and you will need to keep metering the water and have to do more changes.. At least once a week if not a 40% once a week and a 25% in the same week. So, when you can, get a meter you can read. Enjoy...
