Help picking an Apex controller

- ph out of the box with the addition of a probe (to add ph to the junior a pm1 module would be needed)
- a display (a big feature, but smartphone or pc could be used as a workaround)
- vdm (have no idea what it is or if I need it)
- legacy support (again, no idea what it is or if I'll need it given my setup)
- upgradability (a big feature - would I need more than 5 aquabus modules for the equipment I've listed above?)

Does this sound correct? Any insight from anyone on the above would be great. Thanks.

I'm really new to all of this, but the above looks correct to me.

The VDM (Variable Speed/Dimming Module) will allow one to control most LED systems (I think) with the exception already noted. It will also allow one to control powerheads (I'm unsure of brand comparability).

I think it is very hard to determine how many modules someone will need. Technology changes things so rapidly. It may be that today only four would be required, but who knows what abilities will be available in a year or two. I personally don't like the limitation of 5 modules.

I still say go with the Apex full system as it has more built in functionality already just in case you upgrade something down the road. I have a Profilux 2ex on the 8'er but if I bought an Apex it would have been the full meal deal because you just never know what might be down the road.

You can expand any Apex model to get any feature offered by the higher models. It may or may not be cheaper in the long run to buy a more expensive model now.

For example, if you think down the road at most you'll add is pH then an Apex Jr. + pH expansion module is cheaper than an Apex Lite. If you think down the road you'll need pH + 8 outlets + VDM + display then the Apex Lite or Apex will be cheaper.

All depends on where you will go, but at least you won't have to throw away your initial investment regardless of your decision now.

Also these Apex units are rarely sold used and keep their value compared to most electronics.
