View Full Version : Tough algae... any ideas?

12/27/2012, 06:57 AM
I've had a redish-brown algae growing on the sand of my tank for about 3 weeks now. I know that it isn't red-slime bacteria, though it does look similar. I have a bunch of sifting hermits, but they cant keep up. I did have an orange spotted goby that was making a dent, but he was killed off by a hitchhiking gorilla crab. :sad2:

Does anyone know what this stuff is or how to kill it?

:bounce3: WELCOME TO RC & THE ADDICTION!! :bounce3:

looks to me like diatoms.. all part of the "new tank syndrome" . It should disappear on its own with time. Just a little patience is all ;)

did you get rid of the gorilla crab?

have you read all the stickies up top? I can't say enough that Reading & Patience is your best friend right now during the cycling process!! is your cycle even complete? how are your water params? are you using RO/DI? or tap?

here are some of those great links I mentioned:

Thanks for the tips. Just to clear up the situation a bit more. The tank is a 2 year old setup. I think it finished cycling, but I did have to do a big water swap back in October. Hurricane sandy knocked out power, and I had 4 fish die.

I am currently trying to get rid of the gorilla crab using the tilted glass method. We'll see if that works.

The water params have been good and stable and I always use RO water.

ok.. sorry on my part.. I assumed it was a new tank *slaps hand* :lol2:

sooo sorry for what Sandy did!!! horrid witch did alot of damage!!!!

good luck with the gorilla! they are a PITA to catch!! I've had 3 in the past! One got sooo darn big.. he made burrows under all my rocks.. and killed snails, ate corals, and got ahold of a fish! big jerk!! I was soooo angry with it.. I stayed up late one night and waited for him with a big grill fork!! he met his match that night!!! a part of me feels bad for the way he came to his end.. but I couldn't take it any longer!!!!

how old is your lighting?
and no trace of trates or phos?

def get that gorilla out before adding another goby (if thats your plan) or anything else for that matter. A fighting conch will help as nassarius will too.

I'm sure another reefer will chime in with even more help for you! Good Luck!!

The LED lighting's new - Radion XR30w G2 (I had the XR30w G1 on there before).
I'll check the nitrates and phosphates today.

This looks like it has promise as well. Simply bait it with a little food. :)

Could be a bit of NTS New Tank Syndrom caused by the shock of the big water swap out and dead fish. Probably had some little critters in the sand die off too. So its not uncomman for the tank to sort of re-cycle when this happens, and then you get some of the original problems associated w/ a new tank IE the Diatomic growth. Threse guys eat Nitrates so by lilmiting them you can slow the growth of the Algae. Might try to export better with a wetter skim and start a little fishy reactor w/ carbon and GFO as well as some competing bacteria found in live suppliments likw StartSmart for saltwater. A good combination will slow their growth until it passes on its merry way.
