Advice on chemi pure

[Proteus]

Anyone using chemi pure (elite)

I have 35g system with no traceable nitrates or phosphates

I run a mce 600 with rowaphos and a aquaclear 70 with carbon in it with cheato in refugium.

Is there a advantage to chemi pure other than eliminating the aquaclear

I would keep using the carbon and rowaphos separately as they exhaust at different times/rates.
