thanks for all the insight. I think it is the airstones clogging because when I first put them in they were fine. Thanks loc nar im going to try to find glass air wand becuase I think by the time I bought and made them myself it would just be too much headache and hassle.

I guess I should of mentioned how long was for the hose. I think the lonest one is a meter in length or so. I actually don't think this is the problem because one of the short lengths that I replaced the stone pumps well, while other short lengths that have been used longer are shitting the bed.

Thanks again all.

Edit: Oh and jack I have tried drip before. I bought the most expensive pump from pet store but it didnt have enough pressure to make it to all the plants. Could you kind of explain how you set up your drips lines or link me to somewhere that explains it?
