Gang Valve

[ebrcknrdg]

Emma.

Which diffusor and 'one way' valve are you using?

Are you getting any bubbles at all?

What mix are you using in your DIY bottle.

Tell all

Andy

The diffuser was a cheap nirox one off ebay, ive tried it twice but the co2 cant even make it down the tube to it, i guess the pressure isnt great enough. The guy said it was fine for DIY co2 but i guess he would say that for me to buy it. Theres lots of bubbles on the ladder though which is great, ill either keep the ladder or try and connect my co2 to the external filter if someone can tell me how this is done. Ive taken out the one way valve i think it was stopping co2 going through, again i dont think the pressure was high enough.

I used the mix off here for the nutrafin and just doubled it all for the 2 liter bottle, everything is working fine touch wood.

Ok, so here we have my DIY CO2 mix. The spare is used just incase i need more CO2 for some reason. It has all been siliconed from the outside, not inside. This is because the wet silicone acted as a lubricent and whenever the co2 got to a slightly high pressure, the tubing simply slid off when siliconed from the inside. (you could silicone it from the inside, which is better, but then you would have to wait 1 day to let it dry before using it, and i'm impatient so that was never going to happen ) Thats about it. Nothing fancy. It literally sits inside my cabinet out of sight with the filter and uv unit. I shake that daily and it keeps up my mix. I swap one every week. keeping the mixes 2 weeks at a time, which by then are totally run out.

Next we have my filter for the CO2, and Yes, it is made from a urine sample bottle. My mum works in the NHS so she liberated one for me...unused obviously That too is siliconed, but the hole is tighter than the silicone too so it makes a tighter hold. This isnt a problem for you as you got a propper one probably off e-bay... Cheat The co2 in tube is extended slightly deeper into the bottle reducing the chance of co2 gunk going into the co2 out tube, but somehow some still manages to escape, (not much)

Finally... and i ran out of attachment space to show my bubbles, the diffuser. I added a cable tie to the end because the tube kept slipping with the last diffuser i had and fell off.

Thats about it. Ne more questions PM me, but i am going out now so i will reply at midnight or 1ish.

Wow thats great thanx!

Emma - Do you mean Rhinox from Aquatic Magic? If so which model 1000,2000,5000. I used to use my 2000 with 1 Nutrafin with no problems. Still use the same one now with pressurised.

If the pressure isn't great enough maybe you have a leak somewhere?

The one way valve is only really for pressurised (although people on here like to use them to stop water syphoning out???

Some have the impression it will stop the yeast mix getting into their tank


Neo8223 - The CO2 'filter' you are talking about is really a DIY bubble counter. You are supposed to have the hose from the CO2 kit almost to the bottom and the hose to the diffusor/filter only in a cm or 2. Then fill with water so that the hose from the CO2 bottle is submerged.

Then the bubble will come from the bottle out of the hose. through the water to the air vacuum in the bubble counter and pass on to your output source, voila buble counter. They are also good for collecting the gunk and not letting build up on the diffusor but that's a secondary purpose.

Hm no its not that make, its got chinese writing on and the name Nirox co2 diffusion spiral. It was working great on my ladder but i found a leak in my coke bottle so i put some teflon tape around the top then screwed the lid back on, it seems to be doing the trick now on the ladder with about 1-2 bubbles per second. Is that enough pressure? Have hooked the diffuser back up and will check it in the morning

i used the one way valve to stop water coming out of the tank and into the bottles. But ive discnnected it now anyway.

It may be that the diffusor is on the requires pressurised.

I can't answer if 1-2bps is enough because that will depend on what your plants are consuming etc. This is why we use drop checkers.

one person will have 30ppm with 1 bps while another will need 4bps to achieve the same.

Its a case of tank sizes, diffusro efficiency, circulation, plant uptake etc so there are many variables, hence no guide telling you for a 125Ltr you need x bps.

As a guide under 2.5WPG with full EI and a heavy plant mass the tank in my sig (sig pic is almost empty compared to now. lol) is getting 2-3 bps of pressurised.

Oh and the plants you asked for, the Hygrophylia Sp is the one that is just behind the Sword leaf (Goes a dark purple closer to the light), The Rotala is the central background plant and the Ludwigia Repens is on the right backgroun behind the slate. The Rotal and Repens both go a peachy/rosy apple colour towards the light.

Like i said i asked the guy and he said it would work on DIY, just fobbing me off i suppose. Will try and get a diffuser you mentioned. I was just asking if 1-2BPS is enough pressure to get the glass diffuser going.

cheers

Should be. I used to have that and a little more sometimes. Trouble with DIY and nutrafins is each mix is never the same. I ended up using 1x2Ltr DIY and 2 Nutrafins all going through the gang valve and I got a fair bit of 'mist' from the diffusor, but way too much hassle.
