Mighty Prawn Posted August 24, 2006 Report Share Posted August 24, 2006 I've read a lot lot lot lot lot of stuff on people making their own live-rock and calling it agrocrete. However, I've never really read much of anything about its use in a freshwater tank. I'm very interested in making my own rock for use in a freshwater aquarium. Has anyone done it themselves? Anyone know enough about this agrocrete substance to tell me if it would be safe in freshwater? I'd be making some cave like pieces mostly, and I'd like to be able to make them as smooth as possible. I've heard that using concrete mixed with sand is decent, but has to cure for months and months and months in constant fresh water changes. That's something I won't be able to commit to due to school unfortunately. I don't mind if it's curing for about a month or so. Anyone? Either way, I'll be documenting my process with photos and a write up for a DIY post I'll make. -Hideo Quote Link to comment Share on other sites More sharing options...
Ichthyosporidium Posted August 24, 2006 Report Share Posted August 24, 2006 Is this going to be used on African cichlids? Because it will make your water very alkaline. Quote Link to comment Share on other sites More sharing options...
Mighty Prawn Posted August 24, 2006 Author Report Share Posted August 24, 2006 Nope, a couple SA cichlids, though. -Hideo Quote Link to comment Share on other sites More sharing options...
cichlidkid Posted August 24, 2006 Report Share Posted August 24, 2006 probably not so good Quote Link to comment Share on other sites More sharing options...
Ichthyosporidium Posted August 24, 2006 Report Share Posted August 24, 2006 Yeah, S/A cichlids do generaly like their water more on the acidic side as opposed to alkaline. I personally would not use this in a setup for the fish you are keeping. Great for most African cichlids though. Quote Link to comment Share on other sites More sharing options...
jvision Posted August 24, 2006 Report Share Posted August 24, 2006 And, that's why you see it for SW, which is very hard & alkaline. Quote Link to comment Share on other sites More sharing options...
Mighty Prawn Posted August 24, 2006 Author Report Share Posted August 24, 2006 Well, anyone know of an alternative for freshwater? I suppose I could just do it with styrofoam and marine grade epoxy paint.... -Hideo Quote Link to comment Share on other sites More sharing options...
jvision Posted August 24, 2006 Report Share Posted August 24, 2006 That's what a lot of people have done. Just make sure you glue it down, or your rocks will be floating around the tank! Quote Link to comment Share on other sites More sharing options...
Mighty Prawn Posted August 24, 2006 Author Report Share Posted August 24, 2006 Hahaha, that would actually be kind of funny! I guess I'll still do a photo write up for it, but it doesn't seem as cool as agrocrete. Ah well! Good thing I asked ;-) -Hideo Quote Link to comment Share on other sites More sharing options...
Ichthyosporidium Posted August 24, 2006 Report Share Posted August 24, 2006 Well, if you want to do this agrocrete, then why don't you build a s/w setup. Problem solved! Quote Link to comment Share on other sites More sharing options...
Oxquo Posted October 7, 2006 Report Share Posted October 7, 2006 You could also coat Your rocks in two part epoxy resin, then You could still see the agrocrete. I have also covered styrofoam with resin. It is quite a bit cheaper than most potable water tank paints and both get You very buzzed so good ventillation is a must. West systems is nice to use and really strong yet flexible. Quote Link to comment Share on other sites More sharing options...
