Do corals grow faster in larger tanks?

What does everyone think? Do corals grow faster in larger tanks? SPS VS LPS?

 

I am going to go out on a limb and guess that SPS grow faster in larger tanks while LPS grow faster in nano...

Water volume has nothing to do with the speed at which corals grow. It's what is in the water such as trace elements and what levels they are at along with other factors such as nutrition, lighting or binding elements that play a role in how speedy coral grow. You can have a 1g tank so for instance, and feed it heavily, provide 6hrs of lighting, and preform a 1g water change everyday and watch it explode or have a 300g tank feed it seldomly and light it for 12 hours a day and watch things grow jyst as well. My entire point is keep up on water quality, provide your tank a scource of nutrition and don't let the nutrients get out of hand that it inhibits your coral from building it's skeleton by preforming routine maintenance and you will have a successful tank if all goes well.

Coral growth is not dependent on water volume, but large corals do grow faster than small corals, and large corals are more often found in large aquariums than small aquariums.

A friend of mine has a 300+ gallon system and he has beautiful acros and other sps. I attribute that to the stability of the large water volume. Once he dialed in his doser so his alk, CA and MG stayed constant his corals began to grow beautifully. Big water volumes make acros that are sensitive to alk swings less vulnerable. Of course proper lighting and flow also play into the equation.

But has anyone thought about any possible nano limitations to growing corals and fish/inverts in nano tanks..I mean the fish surely don't grow as big because they are stunted in the smaller environment. What would make anemones or corals any different?

My Nuvo has high flow...good light, clean water. And my corals are growing painfully slow. Granted; my Duncans are exploding - maybe a head every week or so. But the SPS...SO SLOW. Painful to watch.

SPS are slow in general. It can take anywhere from 3 months to a year for a fragged coral to stop being traumatized and be comfortable enough to grow. The growth and success of tank propagated corals is much better than maricultured. I also feel many aquacultured corals also take time to adjust to a hobbyists tanks due to the raceways being lit with halides. This is changing but not rapidly enough.

Strength in numbers. A colony of 25 polyps grows faster than a frag of 3.
