Hello, I've had this reef tank for 4 years now, and it just hasn't turned out the way I had expected, the thrill is gone. Since last November my tank has slowly declined. My tank parameters are fine, too much Cr in it though. (I have gotten cut that down by 50%). But chemistry doesn't seem to be my problem. My current situation is that due to some back-to-back alk spikes I've lost almost all of my SPS. There is this very small like evasive clove that is taking over. I have tried using anti-Aiptasia products on it, but it still comes back. I've tried using a tooth brush on it and it kills the fish. There is a minor majano infestation.

So, the goal of this re-set is to get rid of this clove like growth, eliminate the manjo, get rid of the many many palys and mushrooms that are simply too many, and restore the thrill of maintaining a reef tank. I would like to keep what I have, mostly very healthy LPSs and one or two SPSs that have survived.

I have a 100 gal tank with about 125 gal total water column. My equipment is working well and sized appropriately. I have only 75lbs of live rock.

1) First off I want to add another 75lbs of rock. I was wanting to add cured clean live rock, void of any organics. I'm going to put that in my sump for a month to get it populated with good stuff and not get overtaken with these cloves or majano. (Anyone can recommend a suitable rock? Vendor?)

2) At that time, separate the infected rock from the good rock, but leave it in the tank.

3) After the month is up start removing the sand bed over 3 weeks.

4) After this is done take all of the infected rock out, removing any corals that I want to save, and boil the rock. I'm expecting that nothing will be left alive on/in the rock after being boiled. (Anyone can recommend how long to boil the suckers?)

5) Put the boiled rock into a bucket with a powerhead and saltwater and keep it there for observation and until there is no or little ammonia in the water. Then put the rock back in the tank.

So, any comments, suggestions, life experiences that anyone would like to share about my plan?

Thanks for listening. Robert
 
I used this rock in my tank and its really good stuff....very porous too.

I don't know if I would throw new rock in your current sump because it will most likely pickup some of the bad stuff your are trying to get rid of.
 
PLEASE- WARNING!
NO NOT BOIL ANY ROCK THAT HAS PALYS ON IT. IF YOU EVEN SUSPECT THAT THE ROCK HAS PALYS ON IT, DON'T BOIL.

Boiling rock with palys on them could potentially cause death. Please be careful.

Thank you for the warning. They do contain some nasty toxins. I was going to boil them outside on my bar b que. I think that should be pretty safe.
 
Don't boil the rock, even outside. You make the poison airborne and you don't control the wind. You have no idea where it will go... This is not a good idea... OMG This is when we read about someone who gets sick and they tell the media they had no idea this hobby was dangerous.
 
If you are trying to kill the rock why not bleach cure it?
I hadn't heard about the bleach method, until now. I looked a BRSTv Investigates "curing live rock", and they covered that topic. And according to them it does look like one of the better methods for curing live rock. It produced cleaner rock more quickly than the 'natural method'. Thanks for mentioning it. I'll give it a try.

How would you recommend I clean this rock, safely? Thanks, Robert
 
Follow the method you already referenced above for bleaching it.

This gentleman has been in the hobby for many years, he did not boil the rock. It's a good video on the dangers. If you boil the rock you can make the toxins airborn. A gram can kill 80 people, a gram.. The challenge is we don't know everything on our rock, so please be safe..

I would agree. I bleached my rock for fear if hitchhikers but it also greatly reduced the excess nutrients

What a wonderful, and scary, video. I'm wondering if minute amounts of toxins are the reason for my tank's slow decline. Thank you for sharing it here. I don't think I will include them in v3.0. Robert
