Canyo or diatoms? Either way I want it GONE!!

So I have 8 spots like the pic below of this maroon colored stuff on my rocks and started on my back glass.  What is it? And how do I get rid of it?  Sorry the pic sucks.  Not sure why I got so small / blurry.

 

It is stringy. I havent actually got a piece in my hand before or touched it in the water. I've scraped a few spots off and it took some muscle to get moving. Some of those spots are coming back. I'll see if I can get a feel on a piece of it later tonight.

 

1350GPH from a Iwaki 40RXT external pump. A Koralina 4 on the left sife of the tank and a Koralina 3 on the right. I'd love to get 2 - MP60s on it but cant afford them right now. Was also looking into splitting off of my dual returns with 2 or 3 loc line nozzels to help reach spaces that could have weak or no flow to them right now but still havent had a chance to get that ordered and installed, but working on it.

@vikubz - The corals ya gave me are loving the water and have already grown in size since I added them on Sunday!

 

Got 2 blue damsels left and the tomato still. He is bully so I like him!

The Kenya tree you gave me is growing like crazy. I've add in a frogspawn, green stag, and a think AJ said it was a pink acropour (cant spell). The frogspawn looks to have split and is growing already. Looks like the other head that was about to die is coming back as well.

Now since we've determined what I got is canyo, how the heck do I get rid of it? I have my mag crazy high. Don't know the actual number but I accidentally poured a whole bag of Epson salt into my 35 gallon trash can that I use for my ATO. I removed half the water into a old 55 gallon tank and added fresh RO to the can that had all the espon salt end up in it to mix it up better. Doesn't seem to have bugged anything with the high mag. Might've made the canyo grow faster.

Once I added in those other corals I started dosing kalk with the cheap DIY build I saw in a BRS video. Works wonders. Been mixing at night, letting it sit and then dosing during the day. I've also been skipping a day between my dosing so that the tank has a change to adjust to the additives. I think I need to get a GFO / Carbon reactor going here in the next week or two to help me clean up the water a little more.

 

I was looking at your isano-pus there Bud and was looking at maybe taking my return lines and making spray bars off of them since I havent had a chance to play with the loc line yet to see if I have a flow issue. I'd like to get 3 more korlina 4's for the tank so that I have 2 on each side blowing back acrossed the center of the tank. 1 set for behind the rock scape since my rocks are pushed close to the back glass. Then another set for the open area acrossed the front of the tank. Or what would be really nice is a pair of MP60s but I need to win the lotto first before I can afford those lol.

I know my lights are either a year old or very close to being a year old. Where did you order yours Bud? I am running 2 - 36" PC Units on my tank that have a 10000K Day light and a 10000K Atinc, I think. I'd like to find a cheap 6 foot light system for my tank where that I can have more than just 2 bulbs. Would like a 4 bulb system so that I can do 2 day light,1 purple, and 1 atinic. Open to ideas, suggestions, visitors (located in Hiawatha), and offers for parts / hardware.

 

Where do you guys get the floss? I do have a 100 micron filter in my sump that I was out with dirty tank water once a week. This week i'm going to throw it away and put down a fresh sheet.

I was thinking my lights were old but I just remembered they've only been running for 4 months but they sat in a guys shed for who knows how long. The tank sat there for 8 yrs. Looking into getting new bulbs just in case they are old and woren out already to see if that helps. Looking at the GFO and carbon reactors still as well. I'll start looking for the floss to see if that helps me pull it all out.

Also looking at getting 4 - 1400 GPH Koralinas. I have a koralina 4 and 3 already but I want the new ones so I can work with a wave maker.
