Help
hi all
i seem to be having a couple of issues with my jetstream 2 and was wondering if anyone could shine some light on the matter.
1.filling of the reactor seems to take hours i don't know whether this is right but judging by a friends jetstream 1 which took all of a couple of mins to fill with water this does'nt seem right.the installation of my reactor is nigh on identical to that of my friends with the only difference being the feed pump which is a newjet 3000 in my case 'tee'd' off my skimmer feed hose where as his pump is a rio 3000 in exactly the same configuration as my own even down to the parts used.
when my reactor is full and the eheim is active the flow rate out of the outlet equates to the inlet and is obviously running as it should.it is only when the eheim is active that the water is able to flow freely through the reactor which makes the filling tap in my case pretty pointless as i would have to fill the whole reactor up by hand to be able to switch on the eheim for it to allow water to pass through freely.hope this makes sense.
2.the second issue i have is regarding the part of the reactor known as the gas/water seperator which is at the very top of the reactor.again i am only going by the way that my friends jetstream is operating which is a jetstream 1.his reactor at the very top has a pocket of gas which is about an inch from the top of the reactor where as my own has no gas pocket whatsoever and as such the water fills the reactor completely,neither of us know the correct operation of these reactors so we can't say which one is right or not as it does'nt say anything in the manual at all.
tonight i will post some pics showing the reactor and installation if this would further help your response to our predicament.
many thanks
jason

I can only tell you how i have mine setup, i have found you need a dedicated pump for the jetsream, i would use a peristaltic pump as you get a constant pressure then.
The outlet pipe should be higher than the top of the reactor, this creates some backpressue and increases the dkH you can get out of it.
i have removed the blue tap on mine and fitted a union where my pH probe holder sits, this drops the pH probe height so you dont get a buildup of Co2 around the probe.
After filling, you can speed this up by just pouring down the pH probe hole with a jug or using a bigger pump and hose. I remove the normal air by removing the hose which recirculates the co2 put my finger over it and turn on the eheim and the peri, this removes the normal air from the reactor. once at the top and water is coming out of the hole where the tube was turn off the pumps and replace the tube. Now you can start the reactor up i run mine at a pH of 6.4 this makes it bubble but i dont get a big gas pocket at the top. If you do this is because its not under pressure as the outlet hose is too low.
Hope that helps a bit

just thought i would say thanks for the tip about lifting up outlet pipe on js1,i had struggled to get kh output up past 15kh with 6.4ph,i now am getting 30kh at 6.4ph with half the co2 bubble jnput.in my case a quater inch gas pocket comes and goes,i run it manualy with check on ph,60 bubbles per min night and 80 bubbles per min day,output is a constant120 drips per min out.i use a tap off gfo reactor prefiltered by putting pump in a 100 micron sock,this tap off is controlled by an ro tap to adjust output-now working a treat thanks again.regards graham.
