Red hair algae and red branch like algae
 

As title says, I've got red hair algae and red branch like algae growing on my older lr. My sand is clean, it's not cyano. It's not everywhere but it is getting long. I've tried looking on the web but not finding anything. Can post pics later, but any ideas and is it a problem? My blenny, snails and crabs don't touch it. Thanks.

Look up "red turf algae"

Here are two links you can use to hopefully find your algae

Thank you, red turf algae it is. I have a couple large turbo snails, they don't touch it. Would either an emerald crab or sea hare work? I know sea hares can starve once the algae is gone, is there alot of demand for them?

It's hard to find an animal that will eat the red stuff. Instead of looking for a remedy, try finding the root of the problem. I had a problem with the stuff in the summer but I knew exactly where it was coming from. By changing out my RO/DI filters and all 8 of my T5 bulbs it eventually cleared up. While you're looking for the cause of it, siphon or pick as much as you can out to keep on top of it. A turkey baster works well.

Urchins are probably the best algae eaters you can get, but they are hit or miss when it comes to red turf algae. The Long Spine urchins are the best algae eaters, but they require VERY large aquaria as they get VERY large. Tuxedo urchins stay nice and small and eat lots of different algae as well. Be aware that urchins also eat coralline algae, so if you like your tank to be all pretty and pink the urchin will eat it all. Tuxedos should be in at least 50 gallon tank or they will not have enough food long-term.

Having said that, all common algae issues in reef aquaria are caused by excess nutrients. More nutrients going in than coming out. So figure out how to lower nutrients; feed less (most people over-feed), employ a better skimmer, siphon detritus while doing water changes, add a powerhead to help keep detritus from settling on the sand, clean your pumps so they flow better again, add a phosphate reactor, add a chaeto filter, check your RO/DI to make sure it is operating at 0 tds, etc. Also, if you have any lower Kelvin bulbs on your tank (10,000K or less) try switching them for higher Kelvin as algae likes the low Kelvin. As bulbs age they also shift in color, so old bulbs will promote algae as well.

The algae started showing up when my tank was fallow. I would feed the shrimp bits of silverside as well as the corals. Fish have gone back in over the last 6+ weeks and are fed once per day, only as much as they will eat. I have a tunze 9012 skimmer, hob fuge with cheato, canister filter that is cleaned thoroughly monthly. For power heads I have an mp10, mp40 and a koralia 750, tank is 55 gl with 65 lbs lr. Lots of snails including sand sifters, and hermits. My last tests showed my alk was low (6). I don't have any other algae issues, I think the branching stuff came in in a coral frag. Any other suggestions, Im not sure if it's over feeding as I'm careful. What else should I be looking for?

Red turf is nasty stuff. My tuxedo urchin does eat it but the little guy jus can't get into crevices and sometimes carries some on it's back which sucks cuz Im pretty sure he helps it spread.

You're best bet is to remove manually. Try the boiling water in a syringe method and blast em. Do small amounts at a time and just keep at it till it's gone. But most importantly tackle the nitrate and phospahtes as best you can.

Another somewhat natural method would be to take a ball of chaeto and spread it out like a blanket over top of the nuisance algae and starve out the turf algae by making it compete with chaeto.

Last option is to take the infected rock and nuke it.

Pictures added
 

Some pictures...there seems like 4 different types here - green, red, wiry, and branch. Also, in the last photo, theres something with green tipped tentacles. I've been watching this for a while, seems there are about 4 heads, they retract when touched, but not into rock, just into a polyp.

Based on NU-2reef, best option is to blast with boiling water? There's another active thread on this method so I will read up on it.

I forgot to mention, I have 2 54w T5H0 fixture, I changed the white bulb last month, was told the blue was fine for another few months. (supplement lighting with LEDs)

Thank you for the help.

Whats in the canister filter? What media are you running? And when was the last replacement of media?

Maybe cut back on feeding to everyother day and make sure you rinse all frozen foods as they are loaded with phosphates
