Thinking of going bare bottom!

hope you are under the age of 5

I use tumbled marble flooring tiles for my bare bottom. They are turning out to be way better then sand! I am planning on having a Zoa garden bottom as well. I'm planning to try and have a single species per tile. Hopefully it will fill out into a cool checker board pattern. The plus side to the tiles is they are turning out to be a neat version of nutrient export. If a tile gets covered in a little too much algae it can be easily removed from the tank scraped, scrubbed, and washed before returning it. Or you can buy some spares and just replace with new ones and bleach the old ones. The tiles do not seem to grown any additional nuisance algae either. substrate and flow!

if you go BB it doesn't stay that way for long due coralline algae growth. I finally got some zoas growing on the bottom of mine but seems they do prefer growing on rubble. Did have a fair bit of monti plate growing directly on the bottom that was neat but lost in my SPS crash.

Here's a link to a Canreef thread showing a GSP bottomed display

just as fast as on rock

Its mostly personal preference I guess. I'm a sand person, always have been always will be. I tried BB in my frag tank for a few months but I didnt like even in there it so I put back a very fine layer.

BB was great for me lots of flow the snails if they fell it was easier for them toget back on there way too. With sand you loose the wrasses that I love, but there is always a down side. Just remember you will get coraline Algae growning on the bottom and that means the CAL and ALk levels will increase alot too.

Coraline algae consumes huge CAL and ALK demands

I agree with the Coraline algae as it has all but completely covered the floor of my tank; however, I also have three Wrasses for over 2 years and they are very happy with their surroundings. Wrasses will get used to no sand and eventually wedge themselves into the rocks at night.

I have a Leopard wrasse in my tank with a BB. At night he just hovers on the bottom near the clown fish normally. I was surprised he does not go into the rock work more often. He is a very friendly fish thought.
