phosphate export

Are the methods below all effective methods of phosphate export?
GFO (reactor or in bag)
Phosban or similar
macro algae
Skimmer?

Am I missing any others?
Are they listed in rough order of effecteffectiveness

GFO in a reactor is the best way to go
Carbon Is a must, my choice is a reactor
macro algae in a deep sand bed refugium
Skimmer is a must, but some ppl have success without it

Just my 2 cents

I stopped skimming and got Rid of reactors.. All the money I was spending on those I added
to more water changes ..IMO nothing beats water changes.. But you can't slack off on it

I have high phosphates in my ro/di water so need something else to help keep them low. Have a RSM130d so want to avoid reactor route if I can to keep the clean AIO thing.

Does vodka dosing help with phosphate export or just nitrates?

 

[Nychris351]

does your ro/di have one of those mixed bed resin cartridges?

 

[nycfishy]

no idea what kind of resin is in ro/di unit, it's what comes standard with BRS 5 stage unit...why do you ask?

 

[Nychris351]

it helps with phosphate and nitrate removal..its better than just running micron filters

I would stay away from adding vodka to your tank. If you have phosphates from your RODI then it does not appear to be working correctly. RODI should not contain any phosphates, it will be added through feedings and fish waste.
There are many macro algae that look nice in a DT and will absorb phosphates. Flame algae or Dragons Breath. Some will uptake calcium so if you have stony corals I would stay away from them.

I gave up on all the chemicals
trying mangroves
100 of hem on a 400 gallon system

Imbarrie....I understood that if my source water is high in phosphates then my ro/di water would then also have some phosphates? Possible this in not true but does seem logical at ro/di systme will only filter 99% of crap out still leaving potential for some phosphates to make it out the other end

 

[Imbarrie]

That is a question better left to the maker of your RODI.

It is my understanding that when you have higher than normal elements in your input then your output flow will be reduced and your filters will deteriorate faster.
If you are running a functional RODI then phosphate in the output should not be traceable beyond the accuracy of the test kit.

How are you testing for this?
How old are your filters?

 

[nycfishy]

using hanna meter to test. RO/DI unit is 5 stage BRS. Filters are about 5 months old with no more than 75 gallons of ro/do water out of them. TDS is is 25 out is 0.

I could be wrong but I'm pretty sure no ro/di will not be able to bring phosphates down to 0 if thye are high on the source side. Could be wrong....maybe some one else will chime in with a few opinions.
