Just a simple question about starting a pico tank.

You may struggle to find a protein skimmer to fit a 6g unless you run a sump and utilise a skimmer there. Filtration would be live rock for biological and maybe a small sponge filter for mechanical. The biggest challenge in a tank this small is keeping parameters stable. Due to the small volume, nano/pico tanks are suscetible to massive swings in pH, alk, salinity etc if not well maintained. The best way to increase the stability and keep the tank clean is to perform numerous small water changes, I would say two 25% changes every week. The beauty of a small tank is water changes are cheap, quick and easy. I personally wouldn't use any filtration other than live rock, water changes and good water movement from powerheads in a tank this size.

On another point, the ccolate chip wouldn't last long in a tank this size, WAY too small. Also, I can't think of any anemones (other than pest anemones) that I would reccomend keeping in a nano tank. Nems generally require a large, mature and stable system.

Hope that helps.

I agree with Matt. I have a 14g nano and that has been a challenge to keep stable. I am not saying it can't be done. I would just choose more forgiving animals to put in it. You could probably do a mushroom garden with some hermits. I have been amazed at how durable my mushrooms are.

No doubt a well planned pico can be quite breathtaking. I wish you luck and keep us updated!
