ident Algae how to treat?

Ya, get that RO sorted out so that you're getting less than 2 ppm tds.

Get some sand sifters for your sand. An Orange Lip Conch or a Fighting Conch would be a good choice for a 45g tank. Sounds like trapped sulphurous areas in the sandbed. You can fix it by stirring the sand yourself, but only do a 2x2x2" patch each day. Release too much in one go and you'll poison your tank. The black patches will stink too.

You definately have excess nutrients in the tank, so take a good look at what's going in there.

OK Will Do.

Also, what would cause the Xenia's to shrivel, and not be active? Im taking it they are a sign of someting bad. They havn't extended and done thir thing in a week

actually Myka No you want to leave the Sand bed alone, let the critters do the sand bed cleaning. IMO and IME sort out the RO unit yes that is a great idea. check to see what youTDS of yoru water coming out of yoru tap. it could be that the city may have been using some kind of chemicals in thewater that bloom algae's.
If your DI is old get it changed out too.
since you have a somewhat small tank you could get a phosban reactor ad nrun ROWA phos to destroy the Phos, in your tank. what type of a skimmer are you using?

Not city water, It's a comunity well system. NO added chemicals though, that I know

I have a Phosban, but pout of Rowa at the moment. Little strapped for cash, but will get some soon

Water
Tap 345ppm

out of RO 9ppm

So I guess I need a membrane and a refillable DI canister. And the fluch connetors for the RO, and fload switches for the storage units, and some sand sifters, and................LMAO it never ends huh

That would be your opinion. That's not a cut and dry matter, it's preference and opinion. I stir my sandbed on every waterchange, but only the top 3/4" or so. I have done it since day one on this tank, so I don't have to worry about releasing a buildup of gases because there isn't any.
