[lufc]

hi reefers...its been 24hrs after i added 500ml biophos into my sump the water still yellowish.

is it normal?

need some clarifications.

thanks guys..

[Golden Tooth]

Wat do u mean by still yellowish? Change water will help.

[ligerton]

No offence, but where and how did you put the biophos?

[blueheaven]

Correct me if I'm wrong, but i do not think Biophos is used for this function.

You can:

1) Improve skimming

2) Use GAC

[damsel-in-distress]

I think Blueheaven is right. BioPhos is a phosphate remover. Activated carbon should be used to remove dissolved organics which usually causes the yellowing in the water. Put 200gm in a netted bag in the sump for a few days and observe if yellowing disappears.

Yup.

[lufc]

ok...thanks guys...

I think it has to do with your skimmer and filteration system.

I am using Biophos too. After the initial addition, the water will turn yellowish for less than 15 mins. Subsequently, you will see a increase in skimmate in the skimmer. That's how your PO4 is reduced.

[lufc]

skimmer is tremendously skimmate...

but the water still yellowish.

anyway will get some activated carbon later on.

One question to ask.. may seem funny.. which part of singapore you stay in? Jurong area? Water quality is different in different part of singapore.

[lufc]

yup...i'm staying around jurong area.

[neokn]

Jurong using NEW WATER?? So there is a differents?

[Gouldian]

NEW Water is actually RO water right?

[alanseah]

new water look more to me like recycle water..

then what about east side water they r what water..??

[aStRoBo|]

NEW Water is actually RO water right?

yeah man.

[XPeriment 626]

Jurong uses different water? Never heard of that. But not saying it's not true, I myself dunno.

NEWATER IMHO does not come to us directly in taps (not yet anyway). It is used for industrial purposes (machine cooling, wafer fabrication etc) and is also introduced into our reservoirs to mix with rainwater before processing for domestic use. The Americans have been using this method for years and seems ok. Apparently raw RO water has zero minerals, which is actually less healthy to drink than the water we normally get.
