Review on IAFVKAI Diffuser Aquarium Atomizer Accessories by April Smith

To be honest I bought this price of 2 for 1 item Unfortunately I didn't Realized that only 1 of 2 is working properly, ie the bubble counter is only working on one of the diffusers and not the other. I always sent the defective diffuser back. The bubble counterpart doesn't work, although the diffuser works fine. Decided not to return again and instead fitted a replacement bubble counter to my CO2 split valve.
