Can you not make it to East Bridgford next Sunday to see Mark's scape? If not we'll sort something out to save posting it I'm sure.sumink fishy said:Looking really good Ed, I love the journal style documentary of progress.
I may need you to post mine as I can't find any time in the next few weeks that I'd be able to collect, shame that as It'd be great to meet you.
I wasn't going to and there's probably not much point. The only thing I can suggest is that they are ran in a bucket at first just in case, but the amount of silicone and SW I have, or will be using, means it shouldn't be a problem. They won't leak!sumink fishy said:Are you going to pressure test these? I don't mind if you're not and maybe better for all involved if they individually test themselves before fitting. If there's a simple way to test maybe you could advise on how to.
No way to test that unless I built a series of reactors of different lengths I'm afraid! I think the way to look at it is that the longer the reactor the more efficient it will be. The 50cm length one I've built still means some microbubbles get through into the tank once the CO2 level in the water gets up to 30ppm. However there aren't many.sumink fishy said:Oh by the way, what was the result in the optimum length of the reactor?
I'll do a post on that below.sumink fishy said:Also, I assume you are going to let us know the answer to the bioballs inclusion and is this an optional extra and will the bioball addition slow the flow rate by much?
Cheers!sumink fishy said:Well done Ed.
These have cost roughly Â£25 plus whatever postage cost to get them to people. However you can only obtain clear PVC pipe in 5m lengths AFAIK.muckagee said:just curious as to ruffly what one of these would cost to build, as i'm looking to buy the lunnapet 16/20mm external reactor for 39 euros
Excellent work Ed, I've been watching this closely for some time because I wanted to know if I should remove the netting from my Aquamas reactor.Ed Seeley said:I have some netting from James and was also thinking of trying some coarse foam in a layer to try and see if that prevented microbubbles returning to the tank but both of those would require cleaning at intervals and I don't want to do that!
There's a slight 'fizz' when a bubble goes in; almost like someone a bit out of breath but very very quietly. I have to get close up the the fitting where the CO2 enters to hear it clearly. This is caused by the CO2 is entering into the tubing ahead of the reactor so I get a high velocity mixture of the CO2 and water at the start which then empties into the low velocity reactor rather than just one large bubble popping out into the water. I really believe this helps the reactor work much more efficiently than just having the CO2 bubble into the reactor too.Ray said:Is the entry of the bubbles completely silent? Mine goes "plop plop plop".
I know that feelin' brother! A big pat on the back from me for doing it, they look great!Ed Seeley said:I want to get them done and sent off now as the delays are starting to get on my nerves, never mind the guys waiting for them! I'm sorry to all of you.
