I posted a few days ago about some sps bleaching after using flatworm exit. Since then quite a bit has happened with my tank.
- Lost a few SPS to rtn
- Chaeto turning clear and dying
- Algae growing all over my rocks that i didn't have before this.
- Acros turning brown

In previous post i mentioned that i didn't have anything close to what i would consider a plague as far as the number of flatworms in my system. I dosed flatworm exit and pretty much immediately went to work siphoning out any flatworms that i could see. Looking back after the issues ive had, specifically with a few acro frags dying i would not repeat this and instead i would just stick to manual removal and letting my wrasse pick at them.

The only thing that seemed out of wack after using the FWE was my phosphates climbed pretty high for my tank (.17ppm) and the next day i had algae on every rock which seems strange that this happened so fast. I've since added a bit more ROWAPHOS and dosed NOPOX so today Phosphates measured .05ppm which is where I'd like them generally.

What do you guys think I could have done other than not dose at all? I lost a few high dollar frags trying to treat something that most people don't consider that big of a deal. This is the second time I've tried non natural remedies to fix 'issues' with my tank and I've paid the consequences each time. At this point I'm pretty much promising myself to not add chemicals to my tank. I did add 1lb of BRS ROX .8 carbon as I read that you should run about a pound of carbon for every 50g (my total volume is about 55g). Do you think this could have caused some of the acro issues as well?

I'd like to hear other opinions, thoughts or personal experiences people have have had using this technique.
 
I'm not sure why you lost corals. I didn't have an issue when I used it once, but I also didn't have that many flatworms.

The GAC recommendation came from where? It sounds excessive, unless the goal is emergency binding to toxins. If you were not using much carbon before, you might have cleared the water of light absorbing substances very fast and caused some light shock.
 
I cannot remember where I read to use that much carbon but I ran it less than 24hrs. It was supposed to be for any toxins released from the dying flatworms. I almost never run carbon and if i do its for a few days and only 3tbs total..

What do you think about the phosphates would that be caused by the dying worms? Things at least seems stable at this point but it was a rough lesson to learn. Would light shock actually cause acros to rtn that quickly?
