strange small red dots on tank walls

hey guys, so i noticed im getting a lot of very small, like ball point pen tip, sized dots on the tanks walls. Ive got a few feather dusters and a few LPSC.. (small frags).. strange thing is, i was moving around a piece of upside down broken pottery (after my poor plate coral died - no he didnt make it) and inside was this long worm looking thing, but it was pretty heavily encrusted and looked kinda like a very thin feather duster body.. looked like a crusty piece of thick spaghetti.. it was gone the next day so it was alive.. I also place a small 8 pound pieceof live rock a few weeks back. So im thinking corraline, worm invasion, or something more sinister.. ill try to get a few pics tonight, but it seriously looks like small dried bits of blood.. and when i scrubbed a few spots it was pretty tough, like tar or something.. hmmm

flipster

by the way, i havent been running a skimmer since my piece of junk "nano" skimmer died (shall remain nameless).. LFS said with a 20 gallon tank and 10 percent water changes every two weeks and i wouldnt need one... but i think maybe i do

 

id get a skimmer on that ASAP IMO. dont know about the red things. maybe once a pic is up it will be ID.

 

yeah zombie im with you, i just did a quick level check.. my ammonia and no2 is always zero, but my no3 is at like 80? what the heck!! im going to pick up a remora c skimmer tomorrow without a doubt following a brisk water change.. i also started adding calcium for my coral and that might be a contributer.. added small increments over a week and calcium is at around 370.. but im freaked, ive never seen my no3 get above 20ppm.. shoot

 

wow you need a reforguim/sump

HI,
I would cut up a few pieces of PVC and cover it with nylon screen and then place it in a small tank I like 20 tall or 30tall. cover it with a few inches of cheep sand, put in a shoe box with some algae add a light a return and you need a over flow return. And you have a handy reforguim/sump that will keep your tank pretty stable and a place to hang the skimmer out of site.
Here's the one I made for a couple bucks it works great. it also stablizes your water level and provides a place for the copods and amphipods to live i recently added tiger pods , I don't like hermits or starfish in sumps only nassirus snails, worm, and glass shrimp. I haven't been able to measure any nitrates or nitrite.

May be the start of coralline algae! Without a picture, I really can't tell for sure!

 

okay sorry guys, ive been working crazy 80 hour weeks (im an animator and shrek commercials abound!!!) so anyway, i finally managed to get an image up for you, but the dots have turned green.. hmm.. lemme know what ya think.. all my levels are good except No3 is around 20.. calciums at 380.. phosphates are zeroed.. ph about 8.1

 

it is coraline, same colors on your rocks in the back ground.
