plenty of room
 

2" is plenty of room for this. if you are still cautious, cover the anenome with saran wrap before applying.

Thanks Chin_Lee I'll take a look around for a bottle like that, and maybe I'll try it this week.

There is however some good news. I think its pretty safe to say that there is no more nutrients feeding the GHA. I say this because any of the places that the urchin has cleaned have remained cleaned for 2 weeks now. The algae does not regrow after Lurchin' Urch has cleaned an area.

thats the proble
 

i think thats the problem with GHA in that once you have it, its not going to just disappear on its own. Like all other organisms in the tank, each and everyone is competing for something. In the case of GHA, its nutrients and as long as you have something or anything that is producing waste (fish/pods/inverts/bacteria on liverock) it will be able to sustain itself. It may not thrive and spread when the nutrient levels are low but there is always something in the tank that will provide just enough nutrients for it to stay.................... or until you decide to poach them.

I went through somthing similar to what you are experiencing but to lesser degree it seems. I tried the sea hare route and similar results as many others; the power heads got them. I will vouch for Drew's sea hare though, it did a wonderful job after I rescued it from a power head. :mrgreen:

Its encouraging to hear that the areas your urchin has cleaned are staying cleaned. So far, my tank is staying GHA free after I eventually over hauled it. My problem was an extreme bio load, which I've since cut in half. How many fish do you have in your tank?

I do currently have a high number of fish in the tank, but originally I just had 3. I hope to return to the 3-4 mark in the next week or so. The current fish are:
tiny orange shoulder tang 1" (going)
tiny kole tang 1" (going)
ocellaris clown (going)
yellow damsel (going)
sixline wrasse
green clown goby
psychadelic mandarin
4x blue chromis ~0.25-0.5" (probably going)

The tangs came to me quite small, needing to be plumped up and accustomed to higher flow. They were originally supposed to go to a 150g, which was supposed to replace the 90g before the crash. They are two of my fish that I want in my big tank (1000+g) which I hope to start in December, or possibly January of the new year. Most of the extra fish are from the 90g crash, and I'm pretty picky about finding them good homes.

what
 

send me a pic of the tangs i need some fish!!!

There are photos from today in my tank thread. Some of the fish are spoken for already, the clown, damsel, possibly the chormis.

I think ditching some of those fish would definately help, especially the chromis.

add a couple of Sea Hare's.....
See my tank Journal post.
They're mowing down GHA like crazy.....

Much easier said then done. My chromis seem to love my overflow. They all purposefully jump into the overflow to ride the current. They are so tiny I would think that the chormis and clownfish make more of a mess then anything! :mrgreen:
