Hi there, my Malawi set up includes lots of plumb slate at the mo, however i want a change up and have been watching videos of Lake Malawi and want to replicate it more accurately.

Are these Cotswold Rockery pieces OK for the aquarium?
Thanks in advance!

Nice looking rocks! A couple UK sites I looked it up on state it is limestone and the other says it is dolomitic limestone. I'm not much up on rock composition but I would buy a piece, clean if off and put it in a bucket of water and monitor the pH over a week or so to see if it changes at all.

That's a good idea thank you

Yes my initial thought was limestone and PH levels.

I found myself a load of rock on Gumtree from a guy who had lots left over from a building project. May be worth trying that avenue as will certainly work out cheaper for you.

I have even seen people advertise rock on eBay with local collection etc
