    Bare Bottom or substrate?

    Here are some bare bottom tanks!

    Please guys list advantages and disadvantages of going BB. It will help alot for all MASA members setting up new tanks.

    I'm really not a fan of BB systems. It looks "unnatural". :nono:

    I also prefer a tank with substrate, it's a breeding ground for pods and other critters and if deep enough could double as a DSB. I believe if the sand is fine enough it would not trap a significant amount of detritus, most of it could anyway be removed by vacuming your tank when doing waterchanges. Plus it looks much better imo!!

    Hey Keyaam. My choice on going BB is because my tank is SPS dominated and my goal is to allow almost zero detritus settlement therefore reducing the risk of nitrate and phosphate issues. I find it much easier to syphon out detritus when doing water changes. At the same time, I can blast the tank with flow without having sand going all over the place.

    I have a DSB in my display tank. Have a look at my tank's pics. Decide for yourself. People say that it is better regarding detritus "being trapped". BB still requires siphoning of detritus, no matter how much flow you have in your tank. In my case, I stir/rake the top 1 to 1.5 cm of my DSB every now and again. 2 to 3 minutes maximum maintenance. The whole tank goes murky for about 40 minutes or so - during which my corals have a feast!
    This keeps my nutrients low enough for my DSB not to become a "nutrient sink".....

    Also - some fish (many blennie's/goby's, wrasses, even tangs) does not like BB, they prefer having a sandy bottom.

    The in-tank sand-bed definitely supplies many micro critters to the tank, as well as assist with filtration.

    BUT - in the end, it is still your decision.

    Yes I should add I have an area in my tank where most of the detritus settles, from there I just syphon out. But after redoing the aquascpaing i need to play around more with the flow.

    i'm also not a fan of BB, my personal preference is open aquascaping with lots of swimming space for fish and space for large SPS colonies to grow out (not just 100's of small frags)

    if you notice most of the guys with BB pack their tanks full of rock to the brim to try hide the glass on the bottom...

    a thin layer of bright white substrate makes the tank look a lot brighter and natural but that's just MHO

    agree love substrate but also like to be able to remove the detritus easily... perhaps throw substrate only in the front and after you have places your rocks.. will cut on cost and allow for less dead spots to occur...

    With BB the detritus will still settle but you can really point flow towards the bottom. Im busy with my new tank and havent decided on what to do. As jacques said it helps with filtration and houses many critters for some of the species we keep.

    i love bb. i like hard flow and don't want to see my sand kicked up by flow. so its much cleaner with bb. easier to clean. although i do like the look of the sand at the bottom of the tank

    now havin a break i am able to read this thread properly and see all the pictures:) love how my tank is up there:) pretty gratifyin, thanks:) i do really like substrate, really do. may add it on later on in life as leslie says, but not now. want to be able to have proper flow without sand being blown away. and not everybody tries to hide the bottom, i thought it looked pretty awesome, just wish i could hide my stand more, but thats old news. and there are plenty of ways to hide the bottom without a lot of heavy rock. i've already started growin my mushroom patch:)

    BB wont look to bad if you have wood covering about 2cm of the tanks glass. I must admit that it's not the most attractive thing without a border:)

    Tobes you mean Silly Partical Substrate :razz:
