    WHATS THE BEST FILTRATION TO USE FOR A SMALL MARINE TANK. I MEAN SMALL 1M BY 450 BY 500. I WAS THINKING LIVE ROCK AND A GOOD PROTEIN SKIMMER. CLASSIC BERLIN SYSTEM BUT IV HEARD THERE SOME NITRATE FILTER GADGET THAT ALLOWS YOU TO KEEP MORE FISH THAN YOU SHOULD. HOW MUCH LIVE ROCK SHOULD BE USED.:yeahdude:

    LR is the best filteration.a decent skimmer is an essential IMO.
    in a tank your size,i would say aboput 15-20kgs LR will be more than enough.
    creating a DSB about 12-15cm will help in nitrate reduction.but at the same time you cannot over stock a tank.

    DSB= deep sand bed.helps reduce nitrates aswell as allows pods to populate
    create a chamber in your sump to house this.

    Macro algae is also great for natural filtration

    Hi Quade - a sufficient DSB is made of sand (at this stage any sand with the following requirement, as long as the sand does not/will not leach chemicals) with particle sizes between 0.05mm and 1mm in size. The more diverse the sizes of the sand particles, the better for micro critter diversity.....
    The sand bed has to be between 120mm and 150mm to work as an efficient DSB filter (to break down ammonia to nitrites - nitrites to nitrates AND nitrates to nitrogen and oxygen!

    Jacques, the bacteria actually consumes the oxygen, leaving Nitrogen to escape into the atmosphere.

    Hi Warr - that is possible, and quite probable, that a certain amount of oxygen gets consumed, BUT not all oxygen is consumed by the bacteria. Remember - the bacteria in the lower/lowest regions of the DSB is anoxic/an-aerobic. They do not live of oxygen. Only the bacteria in the upper regions lives off oxygen....

    You can get Actinic T5's (globes only) from The Lamphouse, at +-R76 each. Alternatively, you can actually use T8's for actinics as well.....

    nothing wrong with the metal halide,you can use it!you'll probably need to supplement it with T5s for colouration aswell as a more even lightspread

    Hi Quare - no - I was saying that you can indeed use the Osram 10000K 150 watt double ended globe. I just meant to say that you should also add either blue/actinic T5's or T8's, to supplement the coloration and to bring out the color of the corals and fish more.....

    You can always try the in-bucket method DSB. Just a water can or something with the sand in. Have a smaller pump running from that single chamber sump into the drum/bucket and overflow back...

    Search the DIY threads, I'm sure I saw a nice thread there on it woth nice pics...
