    Morning to ALL.

    I have been doing some reading and I am not getting a direct answer.

    My tank is 350 deep and I am currently running 4 39W T5 tubes and it looks like the coralline algae on the rocks are not nice and pink anymore they are going white, does this mean I have too much lighting or to little?

    I would guess to much as I can see the rocks where there is not as much light the coralline algae is still nice and pink.

    So what do the clever guys think, is 4 39W T5's enough for this depth or too much

    should be enough
    What is your calcium levels?

    Not sure about the levels, will have to check.

    2 Marine glo's, I think that’s what they are and then 2 reeftek's I know I should have reefteks but that’s all the budget allowed me to afford when I bought them.

    marine glo's are more expensive than reeftek.. anyway I doubt its too much light. As RiaanP mentioned, it could be your Ca levels are off

    Okay I will check the CA Levels, but would it be worthwhile in adding 2 more T5's?
    Will it make any difference, with regards to growth and overall health off the whole system?

    Well what are you keeping in terms of corals, and how are they doing currently?

    It seems you may not be monitoring your calcium and maybe your alkalinity regularly. Start doing this and adjusting your dosing if necessary and then if your growth has not improved maybe consider adding another 2 tubes - but 4 should be fine on that depth.

    Well Corals are happy, I dont have many, but Pulsing Xenia's I managed to frag 3 times already, Pin cushion is growing well and GSP is spreadng, so everything looks fine.

    But I will check Calcium, I know Alkalinity is fine, just need to check calcium.

    thanks again though.

    So mostly (all?) soft corals then. I think your current lighting is more than sufficient. If you plan on adding LPS/SPS later then possibly look at adding the extra tubes (if necessary), only then.

    What corals are you keeping? I had good coraline growth with just 4 crappy T5's .. Another 2 wont hurt though

    Well all softies for now but maybe later SPS, So I will add the other 2, but want to get descent Giesemans later..

    Coralline requires very little light. I've found that it bleaches with very low nutrients. As soon as these increase it'll regain colour. The most important factor in growing coralline IMO is high flow, then adequate Ca, Mg and alkalinity.
