cement for DIY rocks
headaches...
Ive read through a bit of the literature online about making DIY rocks out of sand cement and rock salt, but what kind of cement should i be using? I know types I through III are fine, but that's American labelling. Canadians use types GU through HS... anyone know what type "I" is in Canadian? oh and hardware stores don't stock rock salt after winter. if anyone has some that i can snag let me know

use type 10 cement. Water softner salt is better anyhow, its cleaner. Also always available.
 The mix I used was 1 part cement to 3 parts "other" other being salt, sand OS ect. With mine I used 2 parts salt, 1 part Caribsea seaflor special grade sand (cause I had some). And 1 part type 10 cement. I just put my first piece in my sump about 2 weeks ago and today I noticed a few spots of coraline on it.

Water softener salt would work too, and is around all year

I've got a couple bags of water softener pellets. Let me know if you want them.
As for the cement, I looked all around town for the low alk cement but no one carries any, so just normal type 10 from homedepot works.

there is another thread on this topic and IMO the rock made with softning salt looks way better. dont bother with the rock salt.

The other thing I considered making some rock out of ... was colored, sanded grout .. It comes in almost any color you want .. so why not have purple base rock?
Though I imagine they would have to be 'ph cured' for a long time
