As Bhu mentioned it will be very silent if its installed inside a cabinet. But you know what? Even if you the sound is audible, its kind of those gentle rippling sound, similar to what you hear near small streams, which is kind of cool.
Since my is Co2 tube is black, I cant say much but as you rightly pointed out with the check valve, very little water can make it backwards. BTW, are you using a full plastic valve or a metal valve? I have noticed that with the plastic ones, the Co2 gas flows easily but with the metal ones, I had to increase the pressure to get that same BPS when I used the plastic ones. One main drawback of plastic valves, they will get brittle over the course of time as the plastic material reacts with the Co2 gas. This is the last think we want in our tank, A seriously leaking valve. Just the thought scares me.
Is that a Pro 3 with a built in heater? Cool
Ahhh, the length we fish keepers would go to to see our fish happy!
When we the last time you cleaned your filter? Maybe the flow could be improved with a cleaner / unclogged filter. Consider removing some filter media if you have too much. For my Eheim 2080, I had 3 layers of filter wool plus the original Eheim pre filter. When I removed just 1 layer of filter wool and the flow improved quite significantly. Just keep a log of your maintenance and you can maintain a healthy flow.

I've decided on the compact + 2000 which can be turned down to 800 l/h which is perfect
I'm up early making sure I don't kill my fish and doing a new pH profile... so far so good Hi Itsai,
Those are some cool looking check valves.
Looks much similar to ADA's.I was in the same dilemma as you when I wanted to setup the two filters. Then I came up with this idea ( OK! I'll be honest, I copied from someone
)Must be quite expensive... How much was it?Hi Itsai,
I get mine from our Green Chapter. I have seen this model only at that place.
I think for a product that works and give less headache is worth the price. Costs me SG$60, money well spent. I think.
Yes it's a pro 3 250T just wish it was the same one wisely has the 600, then I wouldnt need an extra pump for my sera 1000. I clean the filters really regular. The filter was done 3 days ago and I took a lot of media out as well. Right now my pipes are spotless as well
Stop it! Your giving me ideasThe problem with the 600 is I had to rent a second home to fit it in to, which results in a really long pipe length

You can eliminate having two spray bars!
What do you think?
Cheers
I have the pipe just not sure how much flow I will loose with where id need to keep it, so would need the 1200! Gulp!
But already so happy as now there is no 7UP effect in the tank. So any bubbles will have to be from pearling plants.Hi
Yup. Same as mine.
Don't be surprise with what you're going to discover
. I have my Co2 BPS like crazy. (Clive aka. ceg4048, once told me that for my 4 feet tank, a 5 liter Co2 cyclinder can easily be used up within 1 month, I was skeptical about that but now I think he's spot on with that one
)Do one change at a time. If not you may not be able to trouble shoot with precision.
If you have your fertz right and nice flow, this reactor will do magic in your tank.
Exactly what I observed today. My Co2 is switched off at 3pm and lights at 4.15pm
The more the merrier.
not so happy with the piping as yet but it will do for now... I have took your suggestion Zak Rafik and made my eheim return just the crook on the right as here... Here are a couple of videos showing the flow and how quiet they are. In the first video the noise is from my low tech tank some 3 metres away. It has an air bubble filter that I made. Thanks for the crook advice works ok I think
