Got no RO/DI unit, so I switch to buying seawater from LFS very month 40L - $4. Hopefully our local seawater is low in phosphate & impurities.

Hi

Whether is a RO or DI, will it helps to eliminate the brownish stain deposited on the sandbed and PH equipments?

your water will be very clean off metals, phosphates etc...

So, RO is better? or DI is better? Or Both RO/DI? Btw How much have u bought for ur RO/DI unit? and for wat capacity tank? Thanks

Haha.. can't compare in this way... Should depend on yourbudget. !!!

if not .. get a Sealife RO unit like the one > decentkid is using. not bad too. replacement cartridge for sealife.. if not wrong >> around $30+.

Esp if you are using rowa and active carbon in your fluidised reactors. a sealife ro unit is good enough.

if you have > 500 -600 > no other place to spend... get a RO/DI unit.. but prepare to spend 30 - 100+ > to replace filter cartridges. range from 4 month to a year +. depend on your usage, and the water condition such as hard water condition.

(just my view.)

Hi

Piglet,

If were to get solely a RO unit from Sealife will it help to eliminate the browish stain? Btw how does this RO works? Pls advise. Thanks

[piglet]

sorrie.. mistake.. i don't think sealife is a ro unit.

For infor on RO system .. read >

DI unit > http://www.aquaticreefsystems.com/TWP_Tap_Water_Purifier.htm

remove browish stain < RO/DI and rowa did remove phosphates... > browish stain .. may be. (not very sure on this)

The strain> is not only browish color rite?
