what are these air bubbles and why are they there? and is that bad algea on the walls on the tank. please help! here are some pics i hope i uploaded them correctly

The bubbles in the sand are probably air bubbles and the other ones probably mean that algae growth is going to occur. Maybe test your water?

How long has your tank been up?

its been up for 1 year + with just live rock and live sand and clean up crew recently just added some corals

i call BS, that sand bed is not a year old...

the algea on the glass looks like cyano

The amount of Spirorbid worms that are in pic #3 would suggest the tank is or was at one time well established.
Why the bubbles now.....I don't know. Have you had a lot of die off or a really high temp spike recently?

eh i am quick to jump the gun, but if he/she has that many worms on the glass, where are the rest of the worms? maybe i havent started a tank from scratch in a while....i carry a bottle of LS and LR when i travel....

post a full FTS and some tank specs!

hm i will try for a full tank shot later the only thing i did was add two piece buffer calcium and alk. and maybe my girlfriend might have added regular tap water for top off. but the algea seems to be getting worst for specs its a 29 tall with 250 metal halide and cpr bakpack protien skimmer. and the kor something nano powerhead. currently for livestock there is hammer coral? maybe frog spawn not to sure lol and a lt plate a slimer and a mushroom with two clown fishes. i waited so long to add in livestock maybe that was the mistake?

I think those may be a sign of Aceteminophor activity.
