I use silicone air line & change it every year or so, I am not sure about C02 line as I have never even seen any!
However If it is supple I would think it would be ok.
The design is adaptable & will even work without the low pressure ceramic stone so you don't need high pressure at all.
I have tried injecting the gas into the main feed pipe using a barbed T connector, this worked with lower flow rates but started to allow bubbles to escape at higher flows around 2000lph.
Thanks foxfish, yes co2 tubing is much stiffer and less supple than airline tubing so probably wouldn't seal too well on it's own as airline does, it may work through one of the push fit connectors though.
😉 it's just that I have enough length of co2 tubing already on my set up to use rather than strip it down and replace, it's fairly new too.
Waste not want not and all that.
Can you confirm again re the ceramic stone you use, these are not the high pressure diffusers then? just an air stone?
Looking at several DIY reactors, I'm certainly doing yours, not that the others are wrong etc, yours seems to have the right size for my cupboard and has been proven and there's a tad less DIY to do etc, looks fantastic.
Great inspiration foxfish, thanks for giving me a push to do this rather than go and spend similar cash on a branded model which may not be upto the task.
Would you say that one 10" model would be sufficient to run in my Vicenza 260 litre bowfront running from JBL e1501 filters without a separate pump as you use? or should I continue with my planned pair running through spray bars the full length of the 4 foot tank?
