When it comes to a controller, I am mostly concerned about precise temperature monitoring/control, live monitoring, ATO integration, and light timers. I can count on one hand how many times ive checked a PH or ORP probe on previous systems, so I decided to forego those functions.
I custom built my Hydros system to fit my needs with coralvue, mostly because they didn't have any XP8 packages available, and I didn't want anything with the hokey little wifi bars... So my system consists of:
Collective:
- XP8 Bar $279
- X3 Controller $199
- Magnet Temp Mount $25
- Command Bus Terminators (2) $10
- Command Bus Cord $10
ATO System:
- Optical Water Sensor $40
- ATO Pump $25
(the kit is $80, if you buy the components separate it comes to $65, so they're
charging you an extra $15 for some airline tubing)
Total System Cost:
$588 (comparable to entry level ApexEL, plus included the impressive Hydros optical ATO unit)
I am still using the Kamoer X1 app and X1s for dosing, Coralvue does not have any good dosing options yet (they make an X1 with hydros command connector, but they cannot be daisy chained, which makes them mostly useless).
I will likely get a hydros 4-head doser option when they release one (prob a rebranded Kamoer F4 with one command bus needed)
