Hey gmacreef done some reaserch. Since following on from ur comments iv since found that cement without lime stops the ph creap. So i bought a bucket of bostick rapid set cementone upon using it i made a piece just cement and dropped it upon 48hours curing. It started to get cyano. So reading more into detail the cement was fine at 65% of the mix but it also has aggregrates undisclosed to what but after a the supplier replied they told me its sand and will be silcates. So…… iv since found that prompt natural cement is perfect as its made for use at sea and adhears to CNP PM NF a standard for sea use. Cheers for ur help

In reply to K hemphrey. Hydraulic cement is generally thought of as reef safe. Pre-soaking is generally a good idea and I soaked all my rockwork in RODI for a week, mostly to get loose dust off the rocks. I have not had any problems.

In reply to KenO. Awesome - I will try that tip with the spray bottle when I cement the rest of my rock pieces. It sounds like the large grain sand would work well. It's nice to cover the dark cement as much as possible. Thanks for commenting.
