Yep and yep If you wanted, you could run some phosphate remover which will also remove silica which feeds the diatoms. they should go away on their own eventually though.
Here are my updated pics..not the best pics but here ya go. This is right over 3 weeks of having the tank going.
I got salinity of 1.024, PH - 8.1, Nitrite- 0 , Ammonia - 0, Phosphate- 0, Calcium- 350, and Nitrate is between 0 and 5 mg. What should my next step be within the next few days? Should I do a water change? Should I go ahead and get some hermits for clean up crew soon? thanks
A water change would be fine, as would adding a cleanup crew, or at least a few snails. Hermits are personal preference. I use them, but there are plenty of people who don't like them.
I heard the snails multiply big time....so the green algae that grows on the glass...whats the best way to control that...I cleaned the glass inside yesterday...the magnet doesnt work on that....but this brush did. and i stired up the top of the sand where the diatoms had covered it.
FW snails do indeed multiply like bunnies, but most SW snails either will not reproduce, or if they do, the eggs are usually eaten by the tank inhabitants. Either way, overpopulation of snails in a SW tank isn't something I've ever seen or heard of.
Anywhere from 10% to 20% should be a fine water change. I don't think there's a need to change out the filter yet, unless it looks particularly nasty. there are no fish, so it shouldn't have filtered much.
Snails do a great job on the film algae on the glass as well.
Ok so my last question is how many snails should I get then for the 29 gallon...seeing as its probly more around 22 to 24 gallons in the viewing area. I do want some hermits as well..the dwarf hermits..so how many hermits and how many snails would be a good number. I appreciate it.
There's no hard and fast rule for a cleanup crew, especially in a smaller tank. While it may be tempting to add a bunch to clean up the diatoms and algae, you'll be better off starting slow and adding more snails and crabs gradually to find a good level.
I'd go with maybe 2 astreas, 2 turbans, maybe a nasarious and a turbo to start., and maybe 5 or 6 dwarf hermits.
If you add the hermits, it may be necessary to add a small amount of fish food (pellet, preferably) once or wice a week for them to eat until there are fish in the tank. They can then scavenge on their own.
As your tank matures and changes, you can add or remove different CUC members t o suit your current conditions.
My suggestions are by no means gospel. In fact, I have always had pretty small CUCs in my tanks, so I'd encourage you to get a bunch of opinions and sort of make up your own mind about what species and how many of what you should add.
I agree with Pearson, start out small with your CUC and build as you see the need. I like hermits too but some people don't. I like trochus and cerith snails too.

Here's the story of the CUC currently in my BC14. I agree with Phust et al. that every tank will have different needs and ecological niches to fill.
My 2 blue legged hermit are pretty aggresive and occasionally take out a snail, but they are great detritovores (along with my peppermint shrimp). My 4 astrea snails are champs @ cleaning the glass. Emerald crab is a great algae eater. My 1 Cerith churns up the sandbed.
