If you want to wash your tanks and rocks, then plain Sunlight Liquid is fine. It is a good disinfectant and if you rinse properly then no residue will be left behind. It will also get rid of the grease on newly cut glass. Do not use any scented detergent, or any ammonia-based stuff like Handy Andy. Just remember to rinse well, and if you can, put the stones or tank in the sun to dry properly. It works for me with no smell or after effects.

I go as far as to taste any thing that I washed to see if there is any thing left behind :laugh: :whistle:.

I been usen dish washing liquid for as long as I been in the hobby and I have lost nothing.
If you rinse it properly and don't try take sort cuts nothing will happen!

F1rely Maybe if you can take some picture of the rock you planning to use cause I'm thinking of ROCKS!!

Decided to hold of on the Rock/Stone thing as I can't find any suitable ones Although if I see one I'll let you know Rather not use what we have in the yard as we have a lot of Concrete "stones" lying around that are very heavy. But think of a Long, narrow, square shaped stone. That's what I'm looking for. Otherwise I'll have to try and find cork bark.
