Live rock requirements

Unread postby nishant.datta » Tue Apr 24, 2012 8:40 pm

I'm planning on starting a marine tank sometime in the near future and was doing some research. Thought I'd share whatever I find to help fellow members and provide a guide for beginners on live rocks. Please feel free to contribute to this topic. My only request is to provide inputs for adding to the topic.

This is by a lay-person for lay persons, so please pardon my limited knowledge on this topic. Live rock are NOT corals. However, mostly the live rock are obtained from the ocean. Basically live rock are rocks with small organisms living on them. Live rock is full of beneficial bacteria which can help with your filtration. Infact, some aquarists only use live rock for filtration alongwith a protein skimmer. Live Rock also has bristile worms, shrimps, crabs and other organisms which help keep the tank clean. and the coraline algeas, feather duster worms, brittle stars, and other hitchhikers which add to the beautiful, natural look.

Abishek, they are illegal to keep for a hobbyist but in coastal parts of country, peoples using it for construction of homes. They are destroying all the eco system of the sea but if a hobbyist keeps a small volume, it is illegal. I am agree with you but also agree to the feelings of a hobbyist. :dua

Ok Rajiv Ji, got it- my concern was that we shouldn't promote any kind of activity which is not legal :)

actually in germany almost all marine tanks are run with live rock + protein skimmer only...but strong pumps are required.
the bacteria in the live rocks are responsible for the denitrification process.
nobody uses a permanent filter, since it accumulates nitrate and pollutes the water.
if any, filters are used only for 2-3 days to clear cloudy water, to reduce phosphate, etc....filled with activated carbon or phosphate absorbers.

i ran my marine tank only with live rocks and skimmer for 2 years , without any problems.

The Live rock itself acts as the biological filter, if you are using a sump, wont need any other filteration. All you need is a good flow in the main tank and through the sump and back. Strive to achieve 10X flow and 20X not being uncommon as well.

As Wojtek has pointed out, use a filter media only when needed. Its really not very difficult to run a marine tank, only simple basics should be right.
