What diy background....?If it's concrete on it, maybe soak it in water for few days, change the water, soak it again.
Do it several times.
That's what most people do with DIY concrete backgrounds =)
Good luck~ Smart people should chime in soon!!
Yeah I tested the rock, it's high in calcite, carbonate. Concrete would have high pH as well.Some people may cut out Styrofoam, silicone it to a glass tank, whip some quick mix concrete, and then dry it. After the concrete hardens, they pour water in the tank and let it soak for the day, if the PH is measured, it's above norm. Therefore, they would fill and drain quite a few times before they use that background. Hope that made a little more sense, but if it's concrete, it will eventually and slowly creep down.
Don't want to use the stone, just wanted to identify and test it. I've already crushed, splitted and pulverised the rock for testing. I work in a lab.Well~ If you really want to use that stone (it's a nice stone). Maybe consider throwing it in a bucket and leave it outside. The rain will constantly soak it for you. Let it sit for the month, see if it'll change the readings.
Lol no worries and I hope everyone can use this info if they encounter this kind of rock in LFS or anywhere else and was wondering!=)
Well, then all I can say is thanks for sharing the info!
