Dupla Reactor 400 problem
Good day
My name is Gabriel and I am living in Romania. I am posting here with the hope that someone can help me with my Dupla co2 system. I have purchased two weeks ago a Dupla Delta S set which has, as you probably know, also a Reaktor 400 included but I do not seem to make make it work properly. I read the instructions manual hundreds of time hoping that I have missed something essential. My current setup is - Dupla co2 bottle of 1kg , Dupla bubble counter filled with glycerine, Dupla co2 long term test, Dupla Reaktor 400 with the 6th hole unplugged, a Hagen powerhead with adjustable flow from 0 to 450 liters per hour connected to the reaktor only, 1 bubble every 6seconds. My aquarium is 80 x 30 x 40cm - 96liters - abt 80liters net,ph 8.5, kh 8. After one week while the co2 was continously on - day and night - the Co2 test still shows the blue color. I am absolutely sure that I have installed the reaktor correctly i.e. completely immersed (actually abt 5/6 cm bellow the surface), the water goes through the black hose in the central chamber (the one with the minicaskade inside),the co2 goes in the 1st lateral chamber and the 6th capacity hole is open/unplugged. My problem is that if I decrease the water flow through the reactor and also the bubble rate (I have succeeded to adjust even down to 1 bubble every 15seconds) some bubbles still escape through the 6th capacity hole in the reactor. If I increase the water flow keeping the same bubble rate or increasing it a bit some gas in the central chamber is pushed down and out of the reactor through the lower screen. I have tried to turn on both the water and the co2 in the same time or first to fill the reactor with gas and then to turn on the water but the result was the same. When I have received the package the co2 bottle was filled with gas. I have not done any test to see if it is co2 inside but I do presume that it cannot be filled with another gas as it has a special valve thread used only for co2. I am telling you this because it looks that, no matter what approach I am using, I am losing too much gas and the color of the co2 test does not switch to green which means that there is not enough co2 disolved in the water. Thanks beforehand for your help. |

Gabriel, I surely hope someone can help you, I am sorry that I cannot...
I just wanted to say, I'm glad you have a sense of humor with your nickname, AlgaeGrower... that's very cute.... I've not seen such a good sense of humor around here in a while... pretty neat.... Good luck... "AlgaeGrower" wrote in message om... Good day My name is Gabriel and I am living in Romania. I am posting here with the hope that someone can help me with my Dupla co2 system. |
Dupla Reactor 400 problem
My current setup is - Dupla co2 bottle of 1kg , Dupla bubble
counter filled with glycerine, Dupla co2 long term test, Dupla Reaktor 400 with the 6th hole unplugged, a Hagen powerhead with adjustable flow from 0 to 450 liters per hour connected to the reaktor only, 1 bubble every 6seconds. My aquarium is 80 x 30 x 40cm - 96liters - abt 80liters net,ph 8.5, kh 8. After one week while the co2 was continously on - day and night - the Co2 test still shows the blue color. Measure the pH vs kH. This is better than the visual test you have. See pH/KH/CO2 table at www.sfbaaps.com under "references". Follow over to the pH over you'll need for a CO2 level of 20-30ppm range for the KH of 8. About 6.9-7.0 or so is good. Now add only CO2 to do this. You can add more bubbles per second or increase the flow rate through the reactor. Might want to plug all the holes on the reactor for now. My problem is that if I decrease the water flow through the reactor and also the bubble rate (I have succeeded to adjust even down to 1 bubble every 15seconds) some bubbles still escape through the 6th capacity hole in the reactor. If I increase the water flow keeping the same bubble rate or increasing it a bit some gas in the central chamber is pushed down and out of the reactor through the lower screen. Try this, fed the bubble into the powerhead's intake instead and tie off the reactor's CO2 input. This way the water and gas will be atomized by the pump first then shot over the media inside the chamber. Plug the last 6 th level hole up etc. This size reactor should have enough capacity for your small tank. I have tried to turn on both the water and the co2 in the same time or first to fill the reactor with gas and then to turn on the water but the result was the same. Don't worry about day to day fluxes in the reactor. Some drop is going to happen but overall just make sure the pH is in a good range all day length long. When I have received the package the co2 bottle was filled with gas. I have not done any test to see if it is co2 inside but I do presume that it cannot be filled with another gas as it has a special valve thread used only for co2. That's very unlikely. I am telling you this because it looks that, no matter what approach I am using, I am losing too much gas and the color of the co2 test does not switch to green which means that there is not enough co2 disolved in the water.
