Have you looked at the Ultimate or Mega that I posted. It is a lot of money but OTOH we are at the beginning of our journey and already have quite an investment that I would like to protect. We may want to upgrade at some point and this system I believe would move right up with us.
I know a lot of people on here love Apex but my very short experience with it I wasn’t impressed and to make it capable of doing what this GHL does right out of the box would cost substantially more. I can’t afford it right now but I’m planning on getting it eventually. Really need to check that lottery ticket I left in the glovebox! Lol maybe I won something.
That is the base I started with on my GHL journey late last summer.
I currently have a Profilux 4, expansion box 2, 3 power bars, 2 Maxi dosers, KH Director and 10 level sensors. I have added modules to allow for more level sensors and an additional temp probe. 2 conductivity probes (salinity), 3 ph probes, 3 temp probes, 1 ORP.
Don't assume GHL never has issues - they do and it can be hard to work with them sometimes.
Right now I have 2 temp probes that were purchased brand new directly from them. They claim all temp probes are pre-calibrated. What they can't explain to me is why one temp port always shows exactly 3 degrees lower than the other ports. Not the probes - the ports them selves. I can move the 2 brand new probes from port to port and the temps stay identical on the port.
I originally had purchased a second KH Director - and these things are not cheap - upwards of $900. Imagine my surprise when I discovered you can not hook up 2 KH directors to a single controller. You can run 2, but one has to be run with a stand alone doser.
While that doesn't seem all that crazy - I mean how many people are going to run 2 Alk monitors / maintaining systems - right? My problem came when I asked them where their platform capabilities and limitations were documented so that I could avoid a $900 mistake in the future. They immediately assumed I was complaining and they simply refused to communicate or acknowledge my question. Which in turn did annoy me to the point that I was going to just sell it all and stick with reef-pi.
Instead - I waited a few days and started communicating with them in a "hey, you guys are so wonderful, and I'm probably stupid etc etc blah blah, BUT, I'm having this silly little problem and I'm wondering if you might be able to help me out" type of communicating and suddenly their support changed to what I would expect. I came to this conclusion after a hand full of GHL users on R2R sent me DMs describing their own personal experiences and how best to work with GHL.
I'll say again too - their cloud service sucks - its clunky and slow and disconnects a fair amount. Doesn't hurt anything other than my lack of patience.
About those cloud services these companies offer. Remember they are not charging you for them - they are "free" for their customers use. However - the systems and software that run all that cloud stuff is not free. It costs those companies a fair bit every month to keep all that up and running. You are paying for that up front with the cost of the equipment. I also believe that is part of the reason these companies feel it's OK for some of their products to be disposable - like the optical sensors from neptune I mentioned earlier. If those keep breaking, people keep buying, that's a revenue stream they can predict and count on to help out with the operational costs of the "free" online services they are providing.
