If you had a test kit, you would know. Get the test kits, and test the water. If your ammonia or nitrite is above zero, or your nitrate is above 40, then it is not enough. That's really the only way to know. And test weekly, because it may be okay now, but in a couple of months, it may not be... especially with the RTC. I know you say that you want to keep your fish, but if you took him back to the LFS, it would give you time to do this project without having to worry about being in a hurry because he's growing so fast. Then you could go and get another one if you wanted. Or you could purchase, as I said before, a 125 off of CL, put just him in it, and be good until he hits 16 or so inches. These are just suggestions.
And I didn't forget about the bass. I left them out because, to me, those ten feet of fish would be your pond's limit. Not those ten feet plus two bass.
