Thanks Ginu.

it kind of looks like not much as far as functionality goes based on that.

Oooo... that would be the day :) Reefing made easy..... a controller that measures the basica parameters... add Potassium to that list :)


With a controller and pumps you don't really have to dose daily:)
I typically check my parameters once a week or once every two weeks and change the frequency of my dosing pumps to handle the demand for different ingredients.

I do tend to measure my Alk quite frequently as Hanna made it super easy and it is a parameter which can easily affect the corals.

Ca should not fluctuate too much and i dose the same amount as the Alk as I use the BRS two part.

Mg is super easy to maintain as it typically doesn't fluctuate much. If you adjust the water change to the same as the display, then this should be a once a week dose, unless it needs to be raised more than 100, then it needs to be split.

Without the variable ports, you can't run pumps and LEDs on profiles without buying an add on module. Power bar is only 4 outlets vs 8. Depends on what you need, now and in the future. The Jr is a good start, and you can add on if you need to.

It depends on what you're looking to run on it... for a Nano I think the JR is perfect, but if you start to add dossers to the mix, a PH probe and extra outlets is always nice... I only have a EB8 on my 120G system and another EB8 would be nice as I'm sure i can find a few things to run off the extra powerbar.
A EB4 which the JR powerbar is in my opinion not enough :)
On my EB8 I run the following:
1. return pump
2. light 1
3. light 2
4. BRS 1.1ml dosser with Alk
5. Skimmer and Tunze ATO
6. Avast Vibe for zeovit shaking
7. Heater (might actually switch this to a couple of fans as the summer is around the corner
8. BRS 1.1ml dosser with Calcium


So it all depends on what your needs are...

I bought the gold. Happy with the purchase, although I don't think the lab grade probes are a must.
