    Hi Brenda

    Just a question on lighting for an RBTA please.:)

    I believe that MH is not needed, but VHO is sufficient for them. Do you agree?

    Also can you please explain what exactly is a VHO light? Is it a normal T5 tube? At Drs Fosters and Smith the VHO tubes all seem to be T12 tubes?

    I am wanting to light a 12" high tank with the most energy efficient lighting.

    Thanks.

    want to know this too - could be interesting. I have T5 lighting and would love a RBTA so if you can keep them with this lighting it would be great

    may I interrupt here?no?

    WELL lol viper we need exact size of the tank first to give the most efficient method but usually mh give more lumens per watt than t5 depends on the exact globe obviously as some t5 globes are more efficeint than some mh globes and so on but generally mh is more efficient...then again on a 300mm high tank t5 would be best as you can mount it much lower for your tank

    what do you want to do?grow frags? how about a few phillips 865's for growth IN T8 format with ultra low cost and then just add a few actinics for frags to colour up

    ive been succesfully keeping a magnifica for around eight months now in a 45cm high tank.4x phillips 865's and 2x blues.

    the reason i'm recommending the 865's for coral farming is its a t8 so it costs less than R20(2 pounds for you:p) plus it is high output.90lumens per watt surely is high output.think even if you replace once a year the costs of globes is nothing!

    as for keeping a RBTA under t5's sure why not as long as you have sufficient amount for you tank size and your tank is not deeper than say 700mm then GO FOR IT I SAY.

    I'm keeping a normal bta under 6 t5's in a tank 50cm deep. At midday the Anemone is about 15-20cm from the top. He could stretch much closer if he wanted to but doesn't so i think it is getting as much as it needs. I'm just not so sure 30cm's is deep enough for a fully grown bta. I might be wrong though. Lets wait for brenda.

    VHO (Very High Output) is T12 fluorescent lighting. T5 and T12 refer to the diameter of the fluorescent tube in 1/8 inch increments. T5 are 5/8 inch across and T12 lights are 12/8 (1.5) inch across.

    T5 is newer technology. It uses less energy and produces less heat. Because of their smaller diameter, you can put more T5 bulbs on a tank. They both have about the same output, and are similar in price. However, T-5 last longer. Given the fact that T5 last longer, produce less heat, and use less energy, T5 is the better choice IMO.

    Both bulbs are sufficient for the RBTA in a 12” high tank.

    BTAs are well known for splitting when they out grow their space. I would not hesitate to keep BTAs in a 30 cm high tank. If I was ever going to propagate anemones for profit, I would go with a 12" high tank.

    I have never used a Phillips bulb. What is the width of the tank? How many and what other bulbs do you plan on using?

    The width of the tank is also only 12". I was thinking of using 3 x 4ft T5's, I'll think I'll just use normal 10000K marine tubes from ATI or Giesemann.

    Interesting, I just got a RBTA about 2 weeks ago and was wondering about the light requirments as I had also heard that T5 VHO tubes were fine for BTA's! I have 4x39watt T5's with reflectors and they seem to keep the nennie happy (so far)! Tank is 45cm deep...Brenda, would you say that reflectors play an important role in "magnifying" (for loss of a better word!!) the globe out put and maximising the "rays" that goes down to the nennie?!?! A little of the subject...do RBTA need to be fed? If so...whats best and how often? Have also read that it is not 100% nessesary to feed them?!?!

    nope thats directly linked to the PAR it gives of for each watt of power it consumes....

    CRI is the spectrum coverage relative to sunlight i would imagine this globe as having a CRI of over 90.

    even if you are going for t5's then as a coral farmer you need to financially justify anything before you go out and buy it.

    now why buy those at premium prices when in fact the best "10000k" tube is the osram 880 t5.

    ask ziyaadb ive had a look at his and researched it aswell...very very good globe!more to the blue side of the spectrum compared to the 865's so very very crisp white look exactly like the 10000k tubes no difference really but awesome lumen output at 88 lumen per watt..use this as your main daylight tube if you dont want to go for the 865's.


    only use the the ati or geisemann for pure actinic to colour up your stuff..well not that the anemone will colour up alot but it will benefit from the added spectrum of a pure actinic or two.

    This one? - T5 Fluorescent Tube 54W 880 Skywhite Osram 54 Watt

    It's 8000K.

    well actually according to osram themselves its 8800k:p so more like 9000k
    but in reality(regardless of if its rated at 8000k or 8800k) remember colour temperature is a subjective value so osrams 8800k is actually a direct colour match to the usual reeftek 10000k or geiseman 11000k ive seen them side by side;)

    that is the right globe to buy,yes.

    Individual reflectors play a HUGE role in getting more light into your aquarium.

    BTAs need to eat. They don't necessarily need to be target fed. Some people feed their reef tanks heavily and the anemones receive food through the regular tank feedings. Every situation is different. For more information on feeding see here: Feeding Anemones - Specialist Anemone advice
