  • Color Temp. in relation to SPS health

    OK, I made it to where I have 250w MH on my tank instead of 175 w..this is on my 75 gallon...anywhay to the question

    Right now I have really yellow 42k I think 250w MH bulbs...will the acros be ok under this low of k rating or do I need to go to 10k like intentionally planned...I am guessing these bulbs will provide quick growth???(the 42k ones)

    thanks

    i have never heard of 42K bulbs?

    also make sure you check your temp so that hole 90 thing does NOT happen again! these 250w MHs will put out ALOPT more heat so beware!

    i would go with 10k since you have supplemtation

        Adam- i would stick with either 10k, 20k, or 14k, or 13k these are the ones used all people in the SPS game.

        i would personally not put that 42k on your tank, do you haev a brand name?

        which ballast are you using?

        look at those links provided by Eric about Sanjays lighting experiments, then pick your bulb you want.

        Its worth the read even if you dont like to read, YOU NEED TO READ THIS!

        then decide, personally i would ditch the 42k or whatever and stick to something more convential.

            prob 4500k grow bulbs.. I would switch them out aswell for the fact these bulbs have to look pretty yellow. Poeple do run low kelvin bulbs, Iwasaki 6500K's.. You will see you best growth from these bulbs cause of the higher Par.. A good xm 10 with actinic though will give you nice results for color and growth.. If you like a little more blue maybe try a 14K with the actinics.. I myself prefer the xm 20K....

              I dont think they are plant bulbs...they are Mercury Vapor Bulbs...if that helps any

                Mercury vapor.. Hmm I am not sure I would be using them at all.. Maybe they are fine but maybe they are not, def get some REAL reef lights Adam... You have to much time and money invested to run lights over your reef that are not meant for reef keeping.. Not trying to sound mean but I would def get some bulbs asap. What ballast do you have ready for your 250's?

                            Greetings All !

                            ...they are Mercury Vapor Bulbs...
                            "Forms of lighting that are not recommended for reef tanks include some mercury vapour and sodium vapour lights, as well as HQL and HQI-NDL lighting which have color temperatures (4300K) and spectrums that aren't ideal. These lights can be used successfully for reef aquariums provided UV emissions are blocked and temperature is managed. With 4300K light, the color of the animals and appearance of the tank is not as good as with a daylight spectrum, but most corals will still grow as long as they receive bright light."
                            - The Reef Aquarium (Volume 1). J. Charles Delbeek & Julian Sprung (1994).
                            Chapter 6, Lighting the Reef Aquarium, p. 189.

                            And yet, things change ... notice that Aquatic Ecosystems is now marketing High Pressure Sodium (HPS) lighting as options with metal halide systems.

                            Trying to save money? Consider the cost of rebuilding the homestead after it burns to the ground because of an inappropriate ballast-wiring-fixture-bulb configuration.

                            Just a thought ...
