Deltec CR Twintech 1500 thoughts and review

Ok considering getting this unit what would be the best regulator to get should I get the Tunze Dual Stage CO2 Regulator or something else?
Also what media is best to use that could be ordered easily ?
Do most recommend and reactor going thru sand/crushed coral to bring ph up?
Total noob in CA reactors always used triton 4 part or 2 part. I also was thinking to order spare pumps just incase would really hate to wait for replacement parts.
anything else I should consider?

Thanks in advance

Hello, one question please. I switched from Triton to Ca reactor Deltec Twintech 1500 with Kalkwasser and the readings fluctuate a lot. KH started at 9. here it was stable for a few days then increace up to 11, here I reduced the reactor dose from 35 liters to 28. Still going up to 12 then the value went down. At KH 9 I wanted to stabilize it and when it dropped below 9, I increased the dose to 30 but KH still decreasing, I increased dose to 33L and it is still decreasing. Now KH is 7.4. Aquarium 1000L SPS/LPS. Thank you

I feel your pain. I have the Aquarium Engineering ARC that went out of business so I bought the Deltec Twintech 1500. I have never been able to get it to keep my Alkalinity stable. I have been trying for months. I give up and go back to the ARC. Then I try it again and same thing happens. I even tried using the night mode and shutting it down at night but that didn't help. You can buy the night mode adapter here for $11.00 dollars instead of $50 if you want to try that.

There is some talk about it here.

Deltec Twintech Issues

Hi Folks, I'm after a little bit of advice. I have had the Deltec CRTT 1500 running for about 6-7 months now. My tank is ~1300l however it isn't heavily stocked at all and so the alk uptake isnt high. I tried running the reactor at the lowest setting (3) and slowly worked this up to (6) over...

The skimmer has a separate dedicated port for Ozone on the Venturi and the generator says no air pump required

When this happens to me it usually means there is no efflent flow. Clogged line / pump or faulty check valve. My pump is in a filter sock and I bought a glass ball check valve which has helped avoid those annoying issues.
