I'm done with the Fission, it's just not worth the energy anymore, these are my opinions only....
To keep it at a specific water level in the POD is tough since the cover is so tightly fitted to the top of the tank when it's closed.
Way too many bubble are escaping into the tank
The air tube is constantly getting in the way.
I'm done, I'm going to look for an alternative solution or just do a 10% water change on a weekly basis...anyone have suggestions on skimming?
