Powerhead in calcium reactor is sealed with Teflon tape(? Used in plumbing)
Wind a Teflon tape around powerheadÃ"šÃ‚¡Ã"šÃ‚¯s electric wire
* See my first calcium reactor photo Ã"šÃ‚¡ÃƒÂ¨
My reactor is simple, silence, saving CO2 and donÃ"šÃ‚¡Ã"šÃ‚¯t stop powerhead anytime for empty water
Design is my own idea
I have no problem in use for 1.5 years, perfect!!
