Thanks for the fast reply. I've never heard of event horizon before. They're spectacular.

Make sure you watch it in HD. Makes a big difference.
Thanks
It handles it no problem. When you say your 618 struggles, what do you mean? The only difference between the 618 and the 624, is how often you will have to replenish the media in the reactor. The 618 should have no problem.
It came from Reef Raft Asia/ Age of Aquariums. It's called event horizon milli

The 618 used to come with a small whisk pump on it that imo doesn't recirculate the media enough to run it on a large tank. Especially with anything other than extra course. I think they may have upgraded to different pumps and made the pump larger than 158 gph which is what it used to push from what I remember.

I have a similar size tank as you & mostly SPS. Though my reef is 2.5 years behind yours. My 618 has been struggling in the sense that I cannot get my alk above 8dkh anymore. I can only put so much co2 in the reactor & open up the effluent so much. I think there is something more involved in a larger reactor other than less frequently having to change out the media. I've asked the same question & really don't understand the difference between one or the other as far as capacity.

Yeah, old version 618 came with a Eheim 1048. Very small pump I believe for that reactor. But not sure how that correlates to handling a larger demand.

The pump is what makes the co2 more effective, so with a larger pump you can melt more media. Also when running the effluent at a high rate the co2 will be able to go right out the drip without getting chopped up. I saw tons of stagnant spots with bubbles sitting in mine before I changed to a larger pump twice the size at the least. After that I had no issues with demand and I had to tune it down a little when it was running wide opened.
All this only pertains to units that have tiny pumps though imo. I have talked with many people who had the same issues with the geo618.
Also what is more involved in a larger reactor is the more media the more surface area your melting, so the more alk and calcium your supplying. It's not just having to change the media out less often, that's for sure.....

I can't believe a 618 can't keep up. What PH are you running your reactor at? What feed pump are using?

The amount alk and calcium coming out of a calcium reactor depends only on the flow going through it, not the size of the reactor. A larger reactor running 100gph effluent will provide the same amount of alk as a smaller reactor running 100gph effluent. I spoke with the owner of Geo about this, and he was the one that explained it to me.
Also I'm running a small sicce pump on my geo 624, and it works great. You don't need a ton of flow for the recirc pump.

For years I've been running my reactor ph between 6.4-6.6. My feed has been tee'd off the return line.

You have your effluent wide open? I guess I should have asked for a pic of your tank first. Lol if that 618 can't keep up, your tank must be jam packed with huge colonies.
I used to run a Korallin 1502, and it kept up no problem. The only issue was I burned through the media so fast, I had to refill it every 4-6 months. My 624 lasts about 18 months before I refill it.

With a larger reactor you can get more effluent out of it, a smaller reactor will have a limit of how much effluent you can produce at the same dkh. Or you may be able to get close but you will be blowing co2 through it that may not even fully dissolve before it's pushed back out. The amount of media in a tiny reactor doesn't work well for supplying a large tanks needs. That's what I have experienced and it's not a effective way to run a reactor imo. I am sure many people can admit they had to upgrade because their small reactors would not keep up with the demand of their tank. There are many ways to run them and most work great, it just comes down to personal preference and the ability of the reactor and media to work with the co2.
I used a sicce pump to upgrade my geo618 from 158gph to 350 or so. I had no issues with idle co2 bubbles in the media after that and the reactor did not have to be tweaked every week.
How many gph does your sicce pump run through your 624?
