Cleaning Flora Flex Bubblers and 3" Matrix Circulators

How do you clean the bubblers?
The 3" Matrix have been used for two flower periods and they are white from high calcium water.
Is cleaning them in CLR an option or do I just buy another bag and toss them?
Thanks Alta

@Carolina Dream'n I just tagged you because I remember you once wrote automate or stay late...not sure if you use flora flex. @Renfro I just tagged you because you have helped with good info in the past.

Give the CLR a try, it might work. The best option is the toss and replace.

I bought flora kleen for mine, I plan on adding some during the last few days so that it will rinse excess salts out of the coco coir, as well as clean my system out. I don't see much salt buildup on mine

the bubblers come apart pretty easy its all 1/4 turn connections it doesn't look too hard to clean them out with a nylon pipe cleaner and a tooth brush, im sure you could use CLR or a vinegar solution with soap or something to clean them up easily
