Reef Safe Cement With Good Local Availability
 

I need a reef safe cement that has good local availability.

I kind of randomly tossed some rock together, and came up with a scape that I love. I want to cement it all together before I move it.

Unfortunately, I built it in the downstairs bathroom: so close to the door that only two of us who live in house can even get the door open far enough to get into the bathroom. :rolleyes:

What can I purchase here in Calgary, pronto, that is reef safe? I've read that Portland #3 is good, but I also think it might have limited availability. I'm not overly worried about silicates: I'm just worried about not killing anything.

lol, wut?

All cements will have an impact on your pH values. Most cements will be safe once you cure them. Are you able to throw the structure into a large tub of water for six weeks?

It is for my contest tank. I won't get quite six weeks, I don't think. I don't remember the first livestock addition date. December 1, maybe? Five weeks? Safe enough to add a Kenya tree. ;)

Oh! Lol. My three-year-old and I are the ones who can get through the door. ;)

I had a brain fart. As long as I used aragonite sand I won't have an issue with silicates. Right? I have some big bits of crushed shells, too.

Home Depot has the regular Portland cement, so I'll just pick up a bag of that for $12. :)

Silicates? I don't think they're going to be an issue... I make all of my frag plugs (250-500 lot batches) out of portland white + play sand aggregate, so you should be fine.

You want Emaco General Purpose or Emaco General Purpose R400. Cures at ph7 and can be used instantly. I used it to build my reefscape in my 280g (2 years running now).

Well would you look at that. Learn something new everyday :D

LOL Albert. Hey I'm a loveable guy. :lol:

Anyhow I guess I should add I used it in my 65g as well. In both tanks I did exactly as you describe you want to do: I scaped out a structure, solidified it with rods and cement then dropped them in the tank. I love the stuff, it blends into the rock perfectly. Coraline has an affinity for it too so it gets covered quickly.

Anyhow if you want some of my leftover bag, you're welcome to come borrow it. Only thing I ask if you could bring the bag back when you're done because I might do some more aquascaping down the road one day. Two tanks and I've only used maybe 25% of it, a little goes a long way. I live in the deep south. PM me if that works.

Thank you for the great info on reef safe cement. I have been making agrocrete rock for my tanks and am tired of having to wait for the ph to come down before using. Takes months for it to get below 9. That is with having it in tubs outside with rain water down spouts from house running into them to constantly flush them, and living on the west coast it rains alot...
Once cured though the coraline sure does love it, covered in a matter of weeks.
Now to track down a supplier out here.

I've read about the thorite cement. I wasn't optimistic about finding any in the city.

I had decided on using this: http://www.homedepot.ca/product/port...t-227kg/958173

But, I guess if it is taking months for Chewie's pH to lower . . . I should really use the thorite if I have the opportunity too.

Hey could I bum a cup of that cement? I would be interested in testing it out for some frag plugs against the Portland white cement I have been using.
