Thanks bro. Yup I know the pump is pretty new, I already have one.. Not so urgent to have it so trying my luck:) Hoping if there is other bro who bought wrong sizing. So can buy over instead of buying new one. More environment friendly.
My cyano is controlled:) Just wanted to increase flow to deter. Yup have read about naulgi, but trying to avoid chemical. But definitely my next resort.
Really appreciate your sharing:)
