The following article written by Daniel Knop is very informative. It is, however, quite weak on the potential risks associated with its use in marine aquaria. I read somewhere that this chemical irritates the gills of fish. Furthermore, alkalinity may be reduced (if I remember correctly).

Very informative and interesting article, Bulent. Thanks for the link.
I think the biggest take away from it is to use LC cautiously and with the proper filtration methods in place.
Wonderful pics Matt.
I've used LC for over a year, no filter sock, first chamber of the sump. I think those that ran into issues overdosed, it's easy to do. I'm now at 1 drop every 3 days after dropping PO4 to undetectable on the Hanna ULR checker (1ppb). I read about people doing a lot heavier dosing and I think that's just asking for trouble, though a filter sock should mitigate some of the issues.
Just my opinion though, no data. I need to get another test done to see if it shows up. Does Triton test for it?
Hey Mark, thanks for your input. Your tank has been my trial tank
And Watchguy Mark, thank you as well..
It would seem that most of the potential advers effects come from extreme use like over dosing and when treating very high phosphates.
Markalot Mark is only using a drop per day ..
Mark could you tell me which product you are using again? Is it phosphate rx?
Clearly it is pretty concentrated..
I am using Brightwell’s phosphate e which must be a little more diluted. I was using 6ml per day and now I will use 4ml per day to try to slow the reduction..
Once I get below .1, I will play with getting a maintenance dose..
I have had no side effects concerning my yellow, purple, or Kole tangs..
I would consider the amount I am using to be quite small and with the skimmer and filter sock downstream, I am confident enough to use it going forward...
I hope that like Mark, I will have to reduce my dosage to maintain a low phosphate level, in the future.
Well.. I will continue to post a weekly update on the phosphate situation..
Now, I just have to get my shy melanurus wrasse out of the frickin tank before my flatworm issue becomes a real concern.. he is eating any shrimp that goes into the tank and I NEED to get some peppermints in there soon!
