[moodster]

Instead of airstones try a nice Submersible pump... I run blumats with 6/9 and DC with not much sediment... maybe a small amount on the sides of the rez but nothing that take more than a paper towel and 15 seconds of my time.

yes will have a look into submersible pump cheers tyga

A lot of nute companies say not to use air stones because they cause fallout. A pump is much better but I only use mine while mixing.

Maybe a circulating pump on a cycle timer, to avoid heating the reservoir?

Edit: I was picturing a submersible; I know they can heat up a clone machine but that is operating at a much higher pressure than just stirring up nutes.

i dont know if i should get a submersible or circulating pump also how many litres pump will i need for a 35 litre res thanks everyone for all your help

Personally I don't think you need a pump. Just get a piece of PVC pipe and stir the res before you check the pH, or after you add something, which should be once a day. Unless your soil smells like anaerobic bacteria or your having root rot issues, there's plenty of air in your medium. You don't need to keep your nutrients oxygenated or anything like that. It would be a different story if you were running aeroflow or DWC, but as long as your plants look healthy, I say just drop the pumps and airstones and see if the buildup goes away. But if you do decide to get a circulating pump just get the smallest one. All it needs to do is stir your res.
