The revolution has started

[Aqua-Digital]

The apex is only 2 pumps and can not be expanded and has to run with an apex controller and also is not wireless, comments at Macna was it was very limited, bulky and expensive for what it is, having only 2 pumps really misses the mark. yes its bright but very restrictive, limited and offers nothing the GHL can do or does. As it needs the apex it really is not in the same product category.

GHL Doser 2
The 3 pump (which can be expanded up to 16 pumps) is $489.00
the 4 pump (which can be expanded up to 16 pumps) is $599.00

both units come with built in level control for ATO and AWC
both units have built in inputs for the GHL kalk stirrers
Both units have a temperature port

The doser also has a PAB port meaning any GHL PAB device can be connected to it (rumour is its virtually a reef controller)

Smart phone ready
