Calcium reactor feed pump CRTT deltec

[Toky916]

OK fine, I'll try it - even thought I have a working pump and a spare.

Controllable 4-Outlet Power Relay Module $44.00.​

If this ruins my Deltec controller, then one of you - who is dead in the water -has to give me your old one.

The way they are making it sound the new pump won’t work with this controller. So I’m sure someone will donate one.

Also anyone have any info for contact in Germany? I personally got this reactor last year and so did others and they all have this issue.

Wondering if they are just going to shaft everyone on replacement.

If there is a DYI way definitely would go that route.

RELAY STRATEGY = FAIL

Well, I tried it. Consistent with what Steve reported, the Deltec Controller seems to know that it is not connected to the proper pump - and the reactor will not start.

Using a volt meter and the four outlet relay - I see that upon startup, the reactor puts out three pulses of 24 v... twice. Then fails to start the circulation pump. This seems to be a trigger to get a signal back from the Jaebo pump.

Thus... the connected relay turned on and off three times - twice. That was it. I tried connecting both the ground and the other wire to the negative side of the relay with the same results.

I watched the reactor start up the normal way on the normal pump to see if it was looking for flow from the feed pump, but that's not it. The feed pump does not actually start up during this apparent testing phase.

GRRRRR!!!

That leaves only one possibility I can think of, which is to essentially make your own controller - using your neptune apex and level sensors and two new pumps.

Thanks for trying mate, of course it couldn't be that easy....

I'm waiting on parts for the solid state relay setup anyway as I couldn't find power boards with 12v activation available in my country. I'll post here with the results once everything arrives, but seeing your update it doesn't inspire much hope at all.

I think baring the purchase of a whole new controller, your final option is the only way to go.

Should be able to keep the original float sensor & use it to activate a Co2 solenoid yeah? (Even using the power board that you've already purchased)
Then like you said, run the reactor with 2 standalone pumps, bypassing the original flow meter altogether.

I think the controller may be sensing that the 12v trigger is drawing no power like the original pump would.
In turn, this could be activating pump protection mode, like when the pump is out of the water or the impellor is bound up. Not sure how to get around that.

must be the same batch we all got, my feed pump also died in the last week. Anyhow i just bought 4 from here:

Jebao DC650 Marine Reef Aquarium Fish Tank Sump Pump & Controler | eBay

Feed mode disables pump for 10 minutes. Eheim Pickup 45 Internal Aquarium Fish Tank Filter. Aqua Nova Round Sponge Filter Aquarium Fish Tank Breeding Rearing Air Operated. 12mm Green Spray Bar & End Cap Compatible Eheim Fluval & Other Aquarium Filters.

I'm in Australia, so I had to use a freight-forwarder to send it from the UK to Australia.

Fool it with another relay pushing back 24 v? I wonder how it could tell that Steve was using the wrong pump

Yes, the original float should wire to an ATO solenoid setup. Autotopoff.com has useful parts for this.

Then, a circulation pump that is adjustable and can be plumbed to the reactor. This might be the hardest part…. The plumbing.

Finally a peristaltic pump or timed dc pump. It could probably be done without a flow meter, but a flow meter would be convenient. Using an apex timer would allow very precise dosing… so long as the pump makes consistent flow.

Does anyone know what the circulation pump’s manufacturer / model might be?

I received notice today that Deltec expects their shipment this week. They will have a combo replacement controller/feed pump for $500. They also will have a replacement feed pump that will work on previous model controllers for $100.

Interesting…. I assume they are different pumps?

 

[steveweast]

No idea….but I hope so.

 

[steveweast]

The new pump arrived today. It is not a Jebao…..and it works just fine. No need for a new controller. It turned out that is was $60.

 

[Toky916]

That’s still a jeabo it’s the 1.2 the new pumps are 1.3, where did you get this one?

I got the pump direct from Deltec.

Ok that’s odd they told me they won’t have the 1.2v pump and told me that to get the new controller. Unless they got some spare old pumps.

The 1.3v looks the same also.

 

[steveweast]

About 10 days ago, Deltec instructed me that their long awaited shipment of new controllers was days away…..and, on that shipment was also replacement pumps for the older controllers. They asked if I wanted just the replacement feed pump or a new pump/controller combo. My controller is from 2021. They said that the new replacement feed pump would work with older controllers.

The pump is working just fine with my controller. It is possible that Jebao is suppling these new pumps but there is no markings other than the Deltec sticker on the pump…..just like the reactor’s circulation pump that has never failed.

 

[steveweast]

My original supplied feed pump was a Jebao branded pump. The blue and black ones with Jebao markings. This one has none of those.

Ok, so I finally got all the parts together to try the SSR option from my previous post, I wired everything together late last night & powered it on.

Now, I'm not calling it a solution just yet, as I need to test it a bit more, but for now it looks like it actually works!

The power from the feed pump cable activates the solid state relay & switches on the DC pump. In this case a old Jebao wavemaker I had laying around.

Next step will be picking up a low power DC pump to run though the flow meter. If all goes well, I assume the same principal can be applied to the recirculation pump too.

Apologies for the garbage video & please ignore the mess of cables. I'll be tidying up & putting it all neatly away in a waterproof junction box.

Will post more updates later.

After some more testing I’m pretty confident that the ssr will work with the feed pump plug, I’m buying a dc pump tonight to try it.

Tried the recirculating pump plug well, no go. The led on the ssr blinks 3 times, then nothing, same as fishtrucks power board.

unfortunately this does not work so the 3 wires to the pump are 2 constant 24Vdc and a signal wire the yellow is signal it transmits a low amp 5v when the pump should be running, the brown and blue are the constant 24vdc.

my guess is there is a vow voltage relay in the pump so when the signal is on activates a relay in the pump and it turns on.

i tried a few relays but had no luck however i was able to use a Arduino 12v relay board which takes a signal wire to activate

i connected a DC to DC Step Down Voltage Converter Module to the 24vdc constant to reduce to 12vdc then connected the Arduino Compatible 5V Relay to a 24v power supply then connected the output to a SSR and then to a sicci pump and its working its full bogan / hillbilly and i dont condone doing this as im not a sparky but it works. my replacement should arrive tomorrow but at least i have a working cal x
