rockstarwiggle Posted May 15, 2014 Share Posted May 15, 2014 Instead of using one sand type. I am considering mixing a few types in my new tank. Does anyone have like a mixed sand bed combo in their tank set up, if so is it mixed or just placed in random spots? I think that I may do crushed coral (maybe near rock set up) with pockets of finer sand under and nearby rock and then have it migrate or mix into a reef coarser sand look towards the glass? I don't it would benefit me to just mix it and dump it? Right? If you could do it over then what would be your ideal sand set up? Quote Link to comment Share on other sites More sharing options...
FarmerTy Posted May 15, 2014 Share Posted May 15, 2014 I think it would work for a little bit but eventually, it would all mix together. The problem with different grain sizes and various inputs of kinetic energy in the tank (mainly from flow and inhabitants) is that it will eventually sort itself. All your fine stuff will end up in the bottom and the coarser materials will end up on top. The ideal sand setup is one with a homogeneous grain size and large enough that it doesn't get pushed around by the high flow in my tank but not too large as I don't like the look of larger grain sizes or crushed coral. 1 Quote Link to comment Share on other sites More sharing options...
rockstarwiggle Posted May 15, 2014 Author Share Posted May 15, 2014 Thanks Ty. I'll keep that in mind. I don't think I'll have crazy flow and I'll punish those inverts that mess my sand up!! Quote Link to comment Share on other sites More sharing options...
Timfish Posted May 15, 2014 Share Posted May 15, 2014 Using different grades will also pack down tighter. Using a course net you can separate the courser stuff out periodicly if you like the look of different textures. You could also use the same technique for different colors like a black gravel.

rockstarwiggle Posted May 16, 2014 Author Share Posted May 16, 2014 Is that a good thing or bad thing for the sand to pack down tighter? Quote Link to comment Share on other sites More sharing options...
Timfish Posted May 16, 2014 Share Posted May 16, 2014 The tighter it backs down the less gas exchange and the more likely anaerobic pockets will form. Some people will argue it's a bad thing but it's what happens with a Juabert system (see Delbeek and Sprung's "Reef Aquarium" Vol III). I periodicly run into anaerobic pockets under rocks or in corners where sand get's built up and don't see any adverse reactions to it being disturbed.

rockstarwiggle Posted May 16, 2014 Author Share Posted May 16, 2014 Thanks. I'll have to read into this. This will be my first time actually putting some thought into tank. Quote Link to comment Share on other sites More sharing options...
Robb in Austin Posted May 16, 2014 Share Posted May 16, 2014 I'd argue that it's a reasonable thing to happen in a tank (sand compaction/separation) as it's a natural type biome. I'd argue that it's better suited to larger systems as the water volume can dilute any potential toxic effects if the anaerobic pockets get disturbed. That said, I think you should go with whatever grain size you like and be done with it. Quote Link to comment Share on other sites More sharing options...
FarmerTy Posted May 16, 2014 Share Posted May 16, 2014 Same, in the end, they all have their positives and negatives so go with what works for you. Sent from my SPH-L710 using Tapatalk Quote Link to comment Share on other sites More sharing options...
rockstarwiggle Posted May 20, 2014 Author Share Posted May 20, 2014 Thanks to everyone who chimed in and aided me in my choice! Probably was a no-brainer. I have read alot over the past week or so. I am going with one type. I went with Carib-sea reef grade. Yup. 1 Quote Link to comment Share on other sites More sharing options...
mFrame Posted May 20, 2014 Share Posted May 20, 2014 I'd avoid the fine to super fine stuff if you have any sandsifters, you'll perpetually have cloudy water with them stirring it up. Quote Link to comment Share on other sites More sharing options...
