Po4 0.27 from ca reactor

[Andicot]

I turn off my ca reactor for 10 days (turn off circulation pump and co2), only run few drop circulation from sump.
I turn off because ca in tank was over 500.
Yesterday i turn on ca reactor and today po4 in outgoing is 0.27.
Is possible that in 10 day my ca reactor has become a biological filter and this high po4 is bacter that dye for low ph?

[blureff]

you have coralline the true one? I task that having stopped the pump of I recirculate is accumulates you the po4 to the inside empties it is washes the coralline one and you make it to leave again

x chi vuole rispondere dice havendo il calcio alto ha fermato il reattore di calcio x 10 giorni,quando e andato x farlo ripartire ha trovato i po4 alti,e chiede se e possibile che sia diventato un filtro biologicoo similare

la mia risposta e stata :
hai la corallina vero??? io penso che avendo fermato la pompa di ricircolo si sono accumulati i po4 i all'interno svuotalo è lava la corallina e lo fai ripartire


spero solo di averlo tradotto giusto e che si capisca dato che uso un traduttore

the coralline one has always concentrations of po4 in its composition, therefore if firm the reactor is always gone emptied and washed if firm the hard one piu to lugo of 3 days

la corallina ha sempre concentrazioni di po4 nella sua composizione,quindi se si ferma il reattore va sempre svuotato e lavato se la ferma dura piu a lugo di 3 giorni

Hi Donetello/Andicot, I'm not sure of exactly what Donetello's last post said, but many zeo-users run their Ca Reactor's effluent through BiPhos, or a Al-base P04 remover in a container above the waterline, enabling removal of P04's from our Ca Reactor, before the effluent drips back into our waters. Can someone plz. translate for our Italian members?, thnx. Bob

agend salt
dice che molti utilizzano un filtro caricato con biphos,messo all'uscita del reattore di calcio,in modo di eliminare i po4 alluscita del reattore stesso

ora mi chiedo in passato avevo provato a farlo,ma oltre hai po4 si e assorbito anche carbonati e calcio
entravo con 32 di kh ed dal filtro uscivo con 16!!630-410!

in past I had tried to make it, but rowaphos have absorbed me also Ionian of ca,

you have found it?

Hi Donatello, yes, RowaPhos also leaches iron into our waters Therefore, the Al3-based P04 removers are safe, but generally need to be changed every 2-3 weeks, depending on the quantity of P04's in the Ca Reactor's effluent. The P04-remover is rinsed clean with RODI water first, then it is ready to be used to remove effluent P04's. Bob

Usually a PO4 measurement of the reactor effluent is not realiable because of the very high alkalinity.

PO4 tests have to adjust the pH within certain values and the very high alkalinity can prevent this from happening. It can then give both false high and low values.

So Habib, will it help if we mix an equal amount of distilled water and test it? Of course we have to multiply the test result by 2 to get the actual PO4 level...

[losmandy]

Farish have you tried measuring your CR effluent for PO4?

For example the Salifert PO4 kit mentions that the alkalinity should be not more than 20dKH.

I can't comment for other brands but I hope/assume that they should have no problems with an alk of say 15 dKH.

So the sample should be diluted to get a low enough alkalinity. Typically effluent output can be 30 - 60 dKH.

In that case I would use 1/4 sample and 3/4 PO4 free water and multiply the result by 4.

what about measuring it using hanna.. It dont seem to be a problem getting the correct reading.

Would depend on the alkalinity.

What sample did you measure (alkalinity value) and how was it checked that the obtained value was correct?

Habib...
Anything in the common PO4 removers that might cause interference in your test when testing directly after the water has passed though it?

I in past had a fact of the tests, using the rowaphos, beyond you have po4 and absorbed also soccer and charges of coal I exited from the reactor with 35 of kh, and you exited from the filter of the rowa with 16 the po4 in income were of 0,21,in exited 0,04 I have used a photometer hanna instrument c100

traslator on
io in passato avevo un fatto delle prove,usando la rowaphos,oltre hai po4 si e assorbita anche il calcio e carbonati uscivo dal reattore con 35 di kh,ed uscivi dal filtro delle rowa con 16 i po4 in ingresso erano di 0,21,in uscita 0,04 ho usato un fotometro hanna instrument c100



gli amici sopra parlano della precisione dei test sui po4 in uscita dal reattore di calcio,in quanto molti test sono sogetti ad interferenze,in questo caso dalla alkalinita overo dai carbonati (kh),la salifert non tollera valori oltre i 20 di kh,quindi si parvlava di diluire la soluzione,e la rowa devessere sosituita spesso,io gli ho riportato una mia vecchia esperienza con la rowa,vediamo che dicono

Generally no interferences from the materials itself unless the sample is polluted with particles from the media.

However, I seem to recall we discussed something similar in the past and IIRC I mentioned possible interferences if the adsorber would start to release stuff previously adsorbed from the water. E.g. fluoride.
