anything over .015 g would be bad I would think.  Oh and I should stress powdered bromine, not the puck kind.

Sorry Tony to hear about your recent RTN issues. I keep my Alk at 8, temp78-80 as for the brown diatoms appearing could be caused by many factors : what's the TDS of your RO water? You do regular water changes and assuming it's also your top up water too. What and how often do you feed your fish? Many frozen foods and dry foods can have phosphates in them. To much DOC / nutrients can add problems and algae is the product of it. Do you have a substrate in your tank? How deep? If shallow I would stir it up during water changes to help with the export of detritus trapped in the sand. Good luck and I do have a frag of red dragon and palmers still when you get things stabilized cheers!

There's a thread on RC about frozen foods and there phosphate levels. This guy used a few different types of frozen foods for his little experiment. In short the conclusion was  the difference between rinsed and not rinsed foods were very very minimal, so very little it barely registered a difference in readings. I will post a link later if anyone's interested in reading it.

I've read that as well. Something about the phosphates being more in the shrimp than in the rinse water so what difference does it really make iirc.

I rinse my PE mysis in my fish net. If anything it makes it easier to spread around the tank so more fish can get at little pieces, rather than a frozen hunk just sitting in one spot, or me pouring in a cup of cloudy goop into my tank. *shrug* makes sense that especially on a larger tank like mine that one cup of a small amount of phosphates aren't going to do much but why tempt the fates at this point.

Even after reading that I still rinse my food, been doing it all along so it's just habit now.

I spot feed all my lps every week with mysis.....I find that when doing this if I don't rinse the mysis shrimp first then my po4 will go up a bit..... If I rinse them then I notice almost zero impact on po4. This is not to say that you should always rinse your po4, just be aware that there is a definite impact on po4 when feeding foods and we can limit the effect by doing certain things. Sometimes I still just throw in some mysis unrinsed to my fish......I do this to feed the corals a little as well....sure it will raise my po4 a little probably but likely not that much. I have found that with proper feedings and not over feeding too much, this should not be what is causing the po4 levels to raise significantly. It is likely something else...... Especially if you do not have some way to combat the nutrients in the water column such as using a method to obtain ULNS and then of course running GFO for po4......in the last couple years I have found it very important to monitor your rodi water for po4. Although the RO membranes claim to last 2-3 years.....mine start to leak all the po4 from my tap water thru after just over 1 year. I still found small traces of po4 in my RO water even after replacing with a new membrane but so small (like 0.01-0.02ppm) that the DI media takes all of it out. I should point out that my tap water is approx. .25ppm phosphate....
If all of this starts to leak thru the membrane then DI will be exhausted much quicker......to the point where it will be doing nothing and before you know it, you will be pouring .25ppm po4 into your tank through your ato and nsw.....
Anyone who is doing a hardcore reef tank, I seriously suggest you get a Hanna ulr phosphorous checker and test all your water..... We should be treating our nsw mix the same way we are treating our actual tank water....when my po4 got high in my rodi I had to run larger amounts of GFO (until I got new filters of course for rodi) and even then my tank was atleast 0.08ppm.....I began to see brown on the SB, hydroids, and my small patch of Pom Pom Xenia went out of control lol. These are my findings and my experience.....I'm just sharing so feel free to comment.

Randy Holmes Farley says that worrying about 0.25 ppm po4 in your top off water is like worrying about having a mint after eating a 32 oz steak dinner.

That doesn't make any sense.  So just pour phosphate into your tank? 

Actually...if I had an lps or softie tank that would probably be fine, but the day I start dumping top up water with .25 PPM of phosphate in the tank...is the day I'm out of the hobby.  Are you sure he said that? 

 

[Pistol]

Yes he said that, when you feed your dumping, po4 is necessary for life and when you do the math for how much your adding through your top off water vs how much water is in your system it works out to be very minor.

Here's the thread, it's post 5, and my bad, he says 0.05 but the thread is discussing as high as  0.18.

[Salty Cracker]

It's funny, I had a brute container that was reading 1.10 ppm (!!) phosphates.  I couldn't figure out where all the bloody phosphate was coming from before I tested the makeup container! 

 

[draper]

push your alk up to 8, drop your salinity to 1.0245. but that's not your biggest problem. its your nitrates. you cant have any!! do you have a sump?  if not, your system just wont jell over the long run. that's what removes nitrates and now you have a natural system. remember water changes in a fresh water tank are done to remove nitrates, they are done in a marine set up to add trace elements. hell if your dosing then you never need to do water changes. sure with your parameters you'll get some success but a lot of disappointment too. 

 

[Salty Cracker]

I don't agree that if you are dosing you don't have to do water changes.  I think it's almost impossible to dose all the trace elements that are in fresh salt mix.

In fact, I know for a fact that even if I dose, feed, skim etc, and don't do water changes, my sps will suffer in terms of colour and growth.
