Phosphates

Hey nick, I think that sounds like a great idea. I would look up some test kits for iodine, and research the additive you are using to dose. People on this forum always say nothing good ever happens in this hobby and that's just the way it is. I think macro algae is cool as well in a DT tank! However you fish my like it in their bellies more than you like it on your rock, so thats something to think about. Reefmonkey has a great fuge he set up beside his tank as well, so it can be done! Good luck with your zoas, one of the neatest corals in my opinion.

Pink, sounds like you got a great setup! I bet your birdnests make a full recovery.

 

Are you making your own water or is it purchased? Is it RO only or RO/DI?
The reason I ask is many utilities now feed phosphates into their distribution system as a form of corrosion control and RO by itself is not always effective without DI.
Check your water source for phosphates too.

 

Nick, that is a lot of phosphates. +1 to AZDesertRat, check your water source to verify zero phosphates. If your source is zero, I'd recommend a water change to start to get it down in your tank and then starting to look for the source....

I buy my water it's RO. I think my problem will correct itself since I changed my method of feedings. I do often water changes as well. Biweekly. . .

 

The Virginia Beach Water Quality Report does not say if they add phosphates for corrosion control but they do use chloramines which requires RO/DI for treatement not RO only which does not remove all the ammonia.
I would almost bet money they do add some form of phosphates after reading the description of the water sources and the lenghth of the pipelines. You need RO/DI and preferrably your own unit so yoy can monitor water quality. RO alone will not treat the water to what we all consider reef standards.
