Of course I bought a spa without knowing a thing about them...argh. I have a Legacy Inspire VS that has mineral build up thanks to my pool dealer's advice...anywho, it is drained and I need to clean the jets and the air filters in the bottom but the question is how??? Are these removable in this unit? I do not see a way to remove the 3 air filters in the bottom but they are clogged. Hmmm... the jets are hard to turn due to the build up....I have also done the acid thing...it helped a little but not much...I still have the rough surface and of course these other issues. The main motor is not running correctly...which I assume is because these 3 filters in the bottom need to be cleaned. Thanks for any advice!!!
