Hello community! I am currently fishless cycling a arc 45l for a couple of dwarf puffers. Just going through a nice nitrite spike so should be cycled in the not too distant future. I have got some tahitian moonsand and a lovely bit of driftwood which I will attach some weeping moss to for the main deco focal point of the tank. I wanted to put some small stones/rocks in to make some interesting places for the inquisitive puffers to explore.
When I was cycling back from work yesterday through an industrial estate I passed by a local plumbers college. Outside the building are two big 'flower beds' which have literally thousands of these two types of lovely looking pebbles and rocks that are in these pictures. Underneath the stones there looks like a kind of tarpooling canvas so the stones are very clean and have obviously been bought to fill the areas.
I took a couple with me and tested them with vinegar last night and there was no fizzing or bubbling from either.
I would be grateful if anyone could tell me if they thought they would be safe for the aquarium, I would clean them in hot water and leave them to see the water quality after a few days. If they are ok I assume that I DON'T boil them?
Thank you in advance, Tony
