Small aquariums (nano)and possible problems with them

Any and all comments and experience invited as replys for this thread so others taking on a nano tank can use the info.

T5 or T8 lighting is fine for shallow small tanks, above 15 inches try to get more intensity.

Change your tubes every 3 months run your lights 15 to 17 hours a day to allow the corals time to feed with low intensity lighting.

You can have as many fish as like in a small tank until they cause stress or damage to each other (and stress removes the mucus coating strength and that protects them from the always present parasites), your biological waste conversion and how hard the skimmer is working will also decide how many fish will survive the size of your aquarium, you are better off with a few very successfully rather than 12 in there and be very careful.

Corals put out very little compared to fish, corals are far easier to keep than fish in a small tank.

Some corals will attack other corals in your tank up to several feet away with micro transparent stinging spider web like weapons and they will kill the entire other corals very qickly,so be careful which ones you put in a small tank.

If no sump than the surface tension has to be broken or your PH will always be a little unstable and Ph in a marine aquarium is absolutely everything!!!!!!

Oh and if you can make up a remote dry section and a remote algae area for a small tank you will do far better.
With a small tank you have to have a skimmer and chiller.

I think that can be problem with a small or nano to aqaurium.
Some are really strange shapes and sizes and the light fitting for it can be expensive and you have to sometimes go with the original bulbs.
Thats my bit?

I have seen the water flow pumps in a nano and they can look so random.
Unless you can hide them they take up like so much of the tank.
Not pretty
