View Full Version : DIY Live rock questions

05-15-2016, 04:42 AM
Lots of videos and advice on You Tube so my questions are hopefully simple.

Instructions tell me to use portland cement but I've seen a few people say any cement will do... thoughts?

Water softening salt is used in a lot of the recipes so I'm wondering if anyone has a local source for this and finally the oyster shell, where will I find it? I was thinking otter co op but haven't had the time to call them yet.

I'm not sure about Vancouver but here Superstore (Loblaws) carries the water softening salt for cheap. Farm supply stores sell crushed oyster shell but I've seen at PetSmart as well, I don't recall the price. I don't want to say for sure that regular cement is cement but I don't think there is a difference. Cement is very alkaline and the rock formations can take awhile to finish leaching out into the water before it can be used in a fish tank. There are other sources of cheap dry rock as an alternate to live rock. Pukani reef rock comes to mind as an example.

Fwiw I just used quikrete hydraulic water-stop cement to hold two rocks together. First time using but it was recommended a few times online. 10ibs was 15ish dollars at lowes, if i recall correctly. Portland is recommended because it wont leach things and i beleave the ph swing is not as bad as other companies.
Interested in your results, Good luck
