Too many snails?

[Chasman]

Beautiful day in Ohio today. After packing up the motorcycles till spring, I was reading one of the books on reef keeping I bought and it said one Trochus snail per 20 gal. Holy Cow !!, I bought three of them on Friday and three Astraea as well !!! I have a 30 gal tank.
They all seem fine and are munching quite well, amazingly well. Did I over do it? I’m in week five of running in my tank, and so far so good. The snails are the only thing in the tank so far. The Trochus are about the size of a quarter or less and the Astraea are nickel to dime sized. At the moment their seems to be plenty to eat.

The Banded Trochus Snail is touted by aquarists of all experience levels for numerous reasons. Like other members of the Trochidae family, the Banded Trochus is easy to care for and very adept at working as your aquarium's cleanup crew. The Banded Trochus Snail normally has a black foot that is an off white/tan color on the underside of the foot. It boasts a pale gray, top- or pyramid-shaped shell. Thanks to the maroon stripes or bands on its shell, the Banded Trochus Snail adds a unique flair to any marine system. Also known as the Trochus, Turban or Top Shell, or Turban Snail, this species of the Trochus genus is the true Banded Trochus Snail from Indonesia. Perhaps what many aquarists appreciate the most is the ease with which Banded Trochus Snails seem to breed in the home aquarium. It reproduces sexually by releasing gametes into the water column. The gametes appear as a cloudy, white substance. Breeding activity is usually sparked by changes in lighting or water conditions. After the gametes join, they develop into free-swimming larvae that eventually settle into your aquarium substrate and develop into mature snails over a period of a few months.
The Banded Trochus Snail is well suited for reef aquariums. As a general rule, you can keep one snail for every two to three gallons of aquarium water. The Banded Trochus Snail is very peaceful and because of its shell shape, it is not easily eaten by crabs. Unlike its close relative, the Tectus Snail, the Banded Trochus Snail can right itself when knocked over.
The Banded Trochus Snail does best in a well-established aquarium with ample hiding places and room to forage. It naturally feeds on algae, cyanobacteria, and diatoms amongst your live rock, substrate, and aquarium glass. The Banded Trochus is also an effective film algae eater. However, they only passively graze on other nuisance algae, such as hair algae.
Like other invertebrates, Trochus sp. is sensitive to high nitrate levels and intolerant of copper-based medications. It requires a gradual acclimation process, preferably the drip acclimation method. If food levels are insufficient in your aquarium, supplement their diet with dried seaweed. Though most Banded Trochus Snails seem to breed easily, there are no distinguishing characteristics between males and females.

The Turbo Snail, a.k.a. Astrea or Florida Turbo, is the most popular snail in the aquarium industry. Turbos are cone-shaped and their shells are often times covered in coralline algae. These snails are tremendous film-algae eaters and will forage on diatoms and other algaes that grow on live rock and aquarium glass. They are nocturnal and do most of their cleaning at night. These snails will continue to grow their shell over time, if the aquarium is kept at proper calcium levels. In nature, Turbos live on large grass beds where they bury in the sand during high tide, and crawl along the grass blades feeding on algae during low tide. Keep one per every two gallons.
