Is this a Pumice Stone? it Floats~

So i read somewhere that a pumice stone can be good for a tank witch makes sense making a wonderful home for bacteria and something cool for moss to grow on.

Well i have this witch i belive is a pumice stone that has been in a rock collection of mine and dont even remember where it came from.

Well i put it in a 1/2g container with water to see if it would effect water PHand all but it Floats. I let it sit for 2 days and even tried to submerge it under another rock to fill it with water but it will just Float!

Any Ideas? I'm thinking just drill a hole into it witch may open what ever air pocket is forcing it to float and if need be put some kind of weight in the hole.

Oh and can someone veryify that it is Pumice? Its a little darker in color because it is wet.

That does appear to be pumice. Can't tell you for sure without a mineral analysis! I don't know of any way to sink pumice other than to artificially weigh it down.

some pumice is dense enough to sink, but unfortunately, your's is not. I had the same problem with a large floating stone. I eneded up burying the sides and endges on the top with sand. Hasn't moved yet.

I think any moss will attach to it as long as you tie it down first.

This one is vary vary buoyant i think i will have to attach it to something or drill a hole threw it an put a heavy weight inside. no way sand will hold this sucka down..

I was thinking of a vary fine moss,,, i think ill just have to look at some difrent moss types and find what i like.

I have a large piece of pumice in my tank. I did the vinegar test on it and it was ok. Mine did not sink so I got a small piece of slate from the LFS and used epoxy to glue them together. Then I cover the thin piece of slate with my substrate. I did not want the pumice to fall if I was in there cleaning or something. It is also easy to drill holes or in my case a big hole to swim through. I have plants that don't like there roots buried stuck in some holes I drilled for them on the side.

75g, pair of gold rams , ABN, 1 adult 2 young discus, 2oto's, 6ADF's, 3 anglefish. 96w 6700k-light 6hrs raised, No C02, Excel, EI dry macro's and micro's, Eheim 2126, 18w UV, 2 Nano 270 powerhead. wall of bubbles for more O2 for such a deep tank.
