    I'm switching to bubble buckets, what is the best air stone to use, or are the rope style better? I have an eco-air 2 pump, output 4.5 l/m per nozzle (2). I have grown hydro drip for a few years, i just used the cheap airstones for my resovoir. I was thing about trying the rope style: http://cgi.ebay.com/Active-Air-4-ft...emQQptZLH_DefaultDomain_0?hash=item2ea9d7502e
    Hook one nozzle to each end of the diffuser, i bet that would male plenty of bubbles! Any of you experienced bubblers ever try the rope style?

    I just picked up a few of these...

    ...from the hydro shop. The 4" are perfect for a bucket. I would recommend purchasing a T connector and running both outlets into one larger airstone. I've found it's the best method for the Eco Plus 2's.

    I just bought 2 of those from my hydro store in SF aswell! These are good because not only do they aerate but they circulate. I have a photo in my grow journal (sig) of my reservoir (55 Gallon) with 2 of those in it. I don't know if they would provide enough splash for DWC though.

    Hey poo, thanks for the input. I'm setting up my first bubble bucket grow after growing hydro drip in rockwool for some years. I just use the cheap walmart special air stones then. I like the looks of the disc, do you use 1 or 2 in 4" disc per bucket? +rep

    I am using 4 18in air curtains, at first they only have big bubbles, but in a few days the pores shrink or something and they produce alot of tiny bubbles like opening a bottle of soda.

    i use flexible air stones as they curl around the bottom of the bucket and everything bubbles evenly.

    Damn, where did you get those? They would work perfectly in my tubs.

    Walmart, the aquarium section, they are $4 each, but they've worked the best so far.

    Yeah, they look pretty cheap but effective because they cover the whole length of the tub. I'll look and see if my walmart carries them. Thanks.

    Hey Sexxxy thanks for your input, the bubble curtains look sweet. What kind of pump do you use, and how many curtains do you run off one pump?

    Any two outlet pump dedicated to 4 curtains. I have a 60gal pump (means that the air pump is for 60 gallon aquariums). One line can run 2 air curtains, anymore and it doesnt feed them enough.

    Always glue your rods down, the suction cups never stick to plastic as plastic bends and lets air in. You can try anchoring the rods down but if you stir the water they move. Best to glue them with a 2 part epoxy and done!

    I've decided to use a 36" flexible rope diffuser with one outlet on either end from my eco2 air pump. A soon as it gets here i'll post a pic of some bubbles.

    Damn, I was going to ask the same question when I re-read over the thread just now. I was looking at these in Walmart today and they are pretty spendy. But if they can make smaller bubbles than my 4" oxystones, I'd shell out the cash.

    Oh, and do the bubbles come out consistently throughout the length of the "airstone"?

    air curtains are great for short term, but i would replace them after each grow as they WILL clog.

    you best bet is getting ceramic air diffuser, they are the white ones. they never clog and give u nice small bubbles. they come in any size from very small half an inch ones, to VERY large ones that are 18 inches long and 1 inch thick.

    your local hydro store should carry them if the store is any good.

    hope that helped
