Alright so here is the plan for the new improved, expanded, much more expensive refinishing of my hardwood floors. After all the comments here and doing a lot of research including a 1/2 hour discussion with my local flooring guy. What a fantastic individual to give me so much of his time and knowledge.
I am going to use waterbased BONA Traffic HD(3 coats), over BONA DriFast stain(color TBD).
This is all "green" low VOC stuff and even though it should not effect the aquarium, I am going to tent the tank and use a computer fan to push outside air via a 4" duct from outside the house into the tent. I needed to tent the tank anyway because of sanding dust so building a duct/plenum is not that much more work.
It turned into a lot bigger job because recoating with poly would have required sanding the main field but the edges could have just been hit lightly and it would not have been necessary to get everything 100% down to bare wood. Now quarter round has to be removed and old finish needs to go completely, including things like under the toe kicks of the cabinets and all corners will need to be hand scraped.
The Finish has a 2-3 hour dry time so after it is tack free(about 30 min) I can turn on the whole house fan to remove anything in the air.
Assuming good weather and my back holding up I plan on doing this project starting late next week. I will update this thread with the results.
Great information! If my floors need to be refinished to complete the repair I will almost certainly follow the same procedure. Probably won't need to tent the aquarium as I could simply block the door to the basement and turn off the furnace fan for the necessary duration. This makes me feel quite a bit better about the possible process.
