(not sure where to post this)
I just wanted to share that I have had wonderful success cleaning Blizzard's tank and plastic plants using Evironne Vegetable Wash. The main ingredients are water and GSE grapefruit seed extract.
His tank ornaments get so slimy with his huge bubble nests!
I rinse 3 times with hot water
I have been using this fruit wash for 4 months now and notice no bad side effects.
I also add the required Fish dechlorninator at each filling before putting him back in his house :)
