    Firstly, I have no professional connection with Eheim, although, I have just checked the label on my boxers and it might as well read Eheim. .:rolleyes:

    Back in January I looked at several reviews of the Eheim Vac. It had a few positive reviews but some did not recommend them for tanks with sand substrate. So I rejected it and moved on.

    3 months ago, I bit the bullet and spent £50 on a vac. I can honestly say I have not looked back since. I use it daily and it does a fantastic job pulling up the debris. With a bit of practice and when positioned at the right distance above my sand, it hardly takes any granules with each clean up. The waste is collected in a neat mesh container and the vac is easy to use. I appreciate many of you will clean with a siphon and I agree this is a fool proof approach in terms of reliability.

    My challenge was that I use a pump to remove water from my tank to speed up the wc process. So I used to find myself having to wrestle with 2 sets of 20m hosing to discharge the waste directly to my garden.

    For me the vac solution has been a success, although time will tell concerning reliability.

    Anyone got a view on tank vacs ? love em, hate em etc

    Hi Salty,
    I used to siphon with a 22mm hose, but alas I need to move 500l through 20m+ of hose, wind around the house and out into the garden. It used to take an age with gravity so hence I hooked up a 3000l/hr pump to speed the process.

    Both - my died about six months ago, after two years of usage.

    I am not bother that much any more, as I changed substrate to sand (where the vac is useless).

    Weak points:
    - nozzle connection broke - I wanted to use silicon to connect permamently, but that means no access to impeller
    - battery cap is too lose - although it should be waterproof, the water managed to get into batteries several times
    - the power switch became erratic - it seemed that the spring inside dislocated or broke
    - finally - you have to clean the filter thoroughly, as it is dense and with time became saturated and less effective (quick wash is not enough)

    I'll let everyone know how it goes re reliability. If I can get 2 years out of it, that would do me fine. I guess if it implodes within the first year there is a guarantee on them,

    I've used one for a while now, its good, but no matter what make of batteries I use they only last a few uses and once they drop just slightly, it struggles to pick up anything other than fine debris.

    I like the concept, all previous comments on cap and switch acknowledged, but would love to find a way of converting it to run off a low voltage adapter - totally water proofed of course!!

    Anyone ever done anything like this?

    Alternativley, I guess I could use a good AA rechargable battery..?

    I have not had this problem but if I did I would go down the rechargeable route. There may be a qualified technician on here that can help on a workaround, but for me holding onto a vac, placed in water and then plugged into even low voltage would be too stressful.
    On a reliability front, 7 months in and up until last week it was still used daily. Some of you will have seen my recent post where one of the dogs chewed the filter bag. I must try and get a replacement.

    I may have to post a new avatar with just the one dog :rolleyes:. Then again I may have to lose my kahunas when the good lady has spotted there was only one. My excuse of he jumped into the discus tank and got eaten wouldn't quite cut the mustard. Then again, he likes to sit in my sporty car and hang his head out of the window whilst his ears flap. Maybe a dog napping :evilgrin:

    The love of my life has a really wide arse and I'm not talking about Beyonce. To get the angle to take out a flapping ear it will also take out my skirts and rear wing. Then again, if I can get a car window diving board. If only I knew which one it was. Votes on which one looks guilty

    Ideal, much easier to use in a bare bottom. I have sand and need to be careful not to remove too much sand when vacing.
