Yup, bought enough to replace the tubing in all 3 pumps. But since I broke one of those fittings I had to use the long piece to drip into the sump.
Roberto, where did you get your fittings from and what size ID are those for?
I use quinine sulphate for ich treatment. I've had good luck with it. Currently got my QT setup with my pyramid butterfly and QS. Treatment is only 7 days compared to copper and hyposalinity. Also no copper contamination. :)
