    I am currently maturing/cycling my tank but I noticed it smells a bit eggy. Is this usual? It's my first open top tank. Is this why I noticed it, or is this not normal? (ammonia/nitrite/nitrates are all high as expected)

    It can smell if it's going off big time, like everything is dying off.
    Was the rock Live beforehand?
    Any shocks from the tank at all? Only reason I ask is that I had a problem cycling once and found the tank wasn't earthed and I had some voltage leakage which in turn led to die off big time and a smell.

    I had some rock(dead) from previous tank and some live which I took from a break down...(which I dipped for 24 hours)

    (also my powerhead/wavemaker has give up so am only using pump and return flow)

    Hmm, wouldn't expect that then. When I cycled this tank, not a single smell and some rock was dry for months and the seeded piece was only out of water for a short time.

    James My tank is 40"x18"x12" deep. Do you think a 6000 l/h wavemaker is too powerful my tank....am in the lookout for a new one mines just give up....

    So, 137 litres.
    I never suggest a single powerhead, but if you need something to get you by then so be it.

    Typical guidelines are:
    Soft Corals - 20x turnover - 2740lph
    LPS - 30x turnover - 4110lph
    SPS - 40x turnover - 5480lph

    I personally think the 6000lph might be too powerful, and if you have sand you'll find it all at the other end of the tank the next morning. You may also find that it pushes water over the sides with your 12" depth.

    So 2x 2000 l/h would be better...my return pump gives 3000 l/h up from.sump,

    You normally discount the return pump because the flow will reduce (usually by half).
    Given the length, I think it might be best to go for somethign like 3 x 1500 kph, maybe even one of those being a 2000lph or so.
    You don't really want to find it's not getting flow near the middle.
