    Hey guys,

    What would be beter and why?
    2 x 70/75w Mh 20k or 4 x 24w t5 2x 10k and 2x atinic ??

    This will be for a sps dominated nano tank.

    Any advise would be appreciated :thumbup:

    Lol getting them is not a problem.The nano im planing is 600mm wide.
    Would just like to know what would be beter 2x70w mh or 4x 24w t5?
    Costing is roughly the same either way...

    I'd Go T5's. You can play alot more with the colour of T5's. If you buy MH's then you stuck with 1 colour. And they are more expensive to replace.

    400 - 450 max depth wise.

    Id did think about that too @Slagter but want the sps too thrive and want all the corals colours to "pop".

    70w play for me go for 150w. I would go for 150w with t5 on each side., the best of both worlds.

    I would go for T 5 on that depth personally. Reasons being ...

    1. Cost of unit , gear , globes etc...remember replacement as well
    2. As slagter said color combo's are more practical on T5.

    If you HAVE to go for MH only I would rather go 150 W....but it depends on what you want to keep.....

    Ok forgot to add, sps very difficult to keep in a nano, thay wont last long. Well give it a try and see but be sure to lose know and again all those sps you buy.

    And another big down side is excess heat from the Mh.

    Not the same, see a tank with a mix of halide and t5, all me can say is awsome.

    Out of curiosity why would you say so? Is it a params stability issue?

    Sps cosumes curtian trace elements to live ect and in a nano the elements gets depleted very quickly.

    And basically the stability/qaulity of the water.

    You can get very good results from T5's , especially in the "mid water" species of SPS.

    But in nano's water quality could become an issue IMHO without a lot of effort

    Would frequent water changes and a certain amount of dosing not replenish those elements.....?

    I dont mean to hi-jack your thread...

    Stability as you sasy is the most important factor when keeping. Its sort of difficult keeping sps in large systems so a small nano a very big challenge, you might keep for a small period but than will lose all. One small mistake on the nano will be sure death for the sps.

    Keeping temperature, salinity, water parametres on a 100 L would be the challenge. Tace elements is just the small part.
