In my opinion, this will strip much more from the water than the filter roll.Early in morning before lights go on i use Koralen Zucht Snow and the tank become rally cloudy for 30 min but the sump water remain clear...

Not sure if you are aware, but if you can find pure, finely powdered, food grade CaCO3 (Calcium Carbonate) it can do the same thing at a much lower cost. I used it for the first time last night. Here in the US a 5 pound bag was $12 USD shipped.

If my reefkeeper ever goes out, i'm going to splurge and get the Apex. Since reefkeeper is discontinued, parts are getting harder and harder to find. So if anything major ever happens to it i'll pull the plug on apexAnd now because i see so many people watching my thread i will as a question here.
I have a used Aquatronica system with a lot of sensors a modules. I have 2 Ph probe, 2 Redox, Temperature, Salinity, Density, Leak sensor, water level sensor and alarm, 4 power bars with 8 sockets each(!!!), SMS module, Ethernet module (Sadly never manage to connect),2 dosing pump with 3 pumps each, i can control all my Tunze 6095 powerheads.
The problem is that all probes it's old and i can't calibrate anymore it's hard to use from controller and i didn't manage to connect with my computer. If i buy this probe will cost me almost half of new Apex start kit system with 4 probe and one powerbar.
What is your opinion, an Apex system really deserve??
It's just so nice to have current parts, and product support. So I would say yes, go with apex

The Apex is nice, but I prefer the GHL. I think the Apex has nicer online software but I have found the GHL to be more reliable.And now because i see so many people watching my thread i will as a question here.

Mine wouldn't stay connected to Fusion. I was having to reboot the head ever 2 to 3 weeks. It was always just an inconvenience and didn't do harm. I think for some people they are a better choice than the GHL but I am very happy with my switch.I agree with @Brew12. I only run pH and temp probes. Neither one of those is too expensive to replace.
Brew, what kind of problems did you have with Apex? Mine is about 6 years old and I'm sure one day I'll need to replace it. I did have a problem with it not updating software correctly(about a year ago) that resulted in my having to have "an appointment" for the Neptune guys to fix it remotely. Updating software is an adventure every time I do it. LOL

And I will say again that yo really know what you talk @Brew12. Thanks. Locks that I'm in a kind of euphoria and I started to add everything I find around into my tank... This Korall Zucht Snow works pretty good but not in my favour. I was Po4 0 since long time before now I'm also No3 0, maibe this is the reason. Thanks again. I didn't understand the proposal of this Snow from being.


How are the corals doing? I know you had concerns with adding so many at once.Thanks so much. Thei words coming from you mean a lot for me !!
