camtang Posted October 16, 2014 Report Share Posted October 16, 2014 So I installed my air compressor over the weekend and hooked up 8 air filters to one line. 5 are fine but the last 3 will not blow bubbles unless they are in the top rack of tanks. Any thoughts as to why? Quote Link to comment Share on other sites More sharing options...

camtang Posted October 16, 2014 Author Report Share Posted October 16, 2014 Should be heaps. It has 16 outlets, I have blocked off 15 of them and am only using the one outlet at this stage. I have a tank sitting about 80mm lower than the rest and it i not putting anything into that either. Quote Link to comment Share on other sites More sharing options...

alanmin4304 Posted October 16, 2014 Report Share Posted October 16, 2014 Is the problem that the ones that don't work have a greater head of water to operate against? Quote Link to comment Share on other sites More sharing options...
camtang Posted October 16, 2014 Author Report Share Posted October 16, 2014 What do you mean a greater head of water? Like a bigger tank volume? Quote Link to comment Share on other sites More sharing options...
camtang Posted October 16, 2014 Author Report Share Posted October 16, 2014 With bubbles Without Also noted that the work in the bottom tank if I hold them half to 3/4 up the tank. Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted October 16, 2014 Report Share Posted October 16, 2014 The head of water is the height of water above the bubbler Quote Link to comment Share on other sites More sharing options...
camtang Posted October 16, 2014 Author Report Share Posted October 16, 2014 Well then yes with the bottom tanks, when the top tanks were filled to the top there was no issues running them at the top. Should I make all of the water levels top and bottom the same making it all equal and even? Quote Link to comment Share on other sites More sharing options...
JaSa Posted October 16, 2014 Report Share Posted October 16, 2014 You loose too much pressure branching of the 4mm air line. Better to run a big (40mm) PVC pipe around your room and branch off that to each tank. Way easier to control each tank plus you wont have (much) pressure loos. I have 39 air filters + three BS bottles running on a pump third the size of yours and I still have to leave three of the spare taps fully open because of too much pressure... Pump feeds big pipe: 40mm PVC pipe runs along the ceiling and every tank got a tap in the pipe: Cheers, JaSa Quote Link to comment Share on other sites More sharing options...
Discusguru Posted October 16, 2014 Report Share Posted October 16, 2014 Did you put a regulator on each of the airline? Quote Link to comment Share on other sites More sharing options...
camtang Posted October 16, 2014 Author Report Share Posted October 16, 2014 Cool will look into that system of air. Quote Link to comment Share on other sites More sharing options...
livingart Posted October 16, 2014 Report Share Posted October 16, 2014 I run same as jasa but run 19mm irrigation line with irrigation taps along it to 4mm airlines to each airstone or filter Quote Link to comment Share on other sites More sharing options...

Discusguru Posted October 16, 2014 Report Share Posted October 16, 2014 If you put the control valve on to each line you can regulate the air flow and all of the filter will be going no problem. Quote Link to comment Share on other sites More sharing options...
camtang Posted October 16, 2014 Author Report Share Posted October 16, 2014 Cool, I will look into that. I was also thinking that with 16 outlets and five filters on each line I should easy have enough to go round. So I have three options now to play with.

ryanjury Posted October 16, 2014 Report Share Posted October 16, 2014 If you put the control valve on to each line you can regulate the air flow and all of the filter will be going no problem. I think Ron hit the nail on the head here if you have every line open to the compressor the air will just go to the air stones with the least resistance to it, if you regulate the air to each one then you should be ok, what I did in my room is run a 5 way gang valve off the droppers off the main line (which was 19mm irrigation tubing) then I could control the air and get them all going.

JaSa Posted October 17, 2014 Report Share Posted October 17, 2014 If you put the control valve on to each line you can regulate the air flow and all of the filter will be going no problem. Still will have the friction problem + if you change one of the 5 filters on one of the 16 outlets you have to adjust / it will influence the other 4 as well. Like ryanjury said: the air will just go to the air stones with the least resistance to it. That means you have to play around a fair bit to get the system ballanced. And then a filter clocks up or a snail gets in there and the whole dynamic changes and needs adjusting again :nilly: Or if you change water and the level drops in one tank it will upset the whole system until you get the water level perfect again. Been there - not doing it again. I rather watch my fish then adjust the 36 filters all the time Cheers, JaSa Quote Link to comment Share on other sites More sharing options...
