Hi,would like to know if i hv cheato in my refugium do i still need to get DI unit?undestand cheato do

Absoub PO4

It does absorb PO4 in the long run. It depends how much and how often your top-up regime is. If it is done in regular-small proportions, there might be a likely hood it is able to manage. However if you tend to dose larger quantities at one go it might be different. I have cheato in my refugium as well, but diatoms do appear when I am lazy by topping up in larger quantities then usual with dechlorinated aged tapwater.

Im using chiller so water evaporation not so high.I intend to get DI water bought frm shop n save for topup.Only problem is water changing worry cheato not able to absorb fast enough.

The idea of using DI water for top up is to firstly avoid introducing PO4 & other undesirable compounds into the tank. (Most people implement this using a DI filter hooked up from their tap water.)

Whereas for Chaeto, its purpose is mainly to absorb nitrates left over from fish poos & food. So these 2 perform different roles.

BTW, a handful of chaeto typically would not be sufficient to handle the PO4 if you top up directly from tap water.

so FR with rowa is better than cheato?

Can't say which one is better. Individual preference. Chaeto is biological, whereas Rowa is chemical.

A fresh cup of Rowa would probably work faster than a cup of chaeto. But then, in the right environment, chaeto keeps growing more & more, whereas Rowa gets exhausted & needs replacement-->$$.
