    Depends on what you want. If you are going fish only then that is not a problem , however if you want to go the coral route then you will have issues.

    T8's dont "push out" as nicely as T5's which have a higher lumens output .... You want to create a light as close to the sun's light as possible (which is what corals love)

    T8's do not have sufficient PAR (Photosynthetically Available Radiation) and PUR (Photosynthetically Usable Radiation) for corals, the majority of corals we put in our tanks feed off the light, they have zooxanthellae within them which provides 90% of the corals food/energy, without this zooxanthellae the corals will bleach and eventually die. Strong lighting is required for the production of zooxanthellae. So basically weak lighting=corals dying. T8's are not strong enough.

    Have you tried contacting our sponsors, most of them will ship to you, also there are some 2nd hand ballasts for sale on the forum if you want to try DIY.

    its possible,BUT you have to be very carefull to not underlight the tank and you still need to use SPECIFIC t8 globes not just the basic run of the mill ones from the local hardware:nono:

    lets try to help you see how many you'd need,whats the exact dimensions of your tank and what do you intend keeping?only softies? stuff like hard corals,anemones and clams can be a bit more challenging to provide enough lighting for.but its possible so it depends what you want to keep?

    Boet i'm sorry to break it to you but your tank is SEVERELY underlit as its quite a big tank.

    simplest solution is replace the red with phillips t8 865's they come in 36w,and then add 3x 250w mh to the tank and you will have enough light for hard corals also.

    I know 3 x 250w mh seems like alot but it is a big tank that you have.you can add 2 x 250w but then you have to make sure light demanding corals/anemones/clams are put more directly under the two 250w mh.maybe make two reefs with the 250w above them and have the free swimming space for the fish less lit up.

    First prize would still be like I said 3 x 250w 14000k added and the red tubes changed to a more suitable colour.like 865's or even pure actinic if you prefer the bluer look.

    because of the size of this tank you would need like 30 x 36w t8 tubes!lol so hence me saying go mh rather less clutter and headaches with replacing globes.also finding the right t8 tubes can be difficult.

    Hi Wildbunny
    There is a couple of places in PE that can supply you with T5 lighting.
    I also bought a tank with T8 and replaced them all with T5, it was a HUGE improvement.
    PM me if you need contact numbers

    er you lost me,you want to put in 54w t8 or t5? can your ballasts handle these or are you going to replace them?most ballasts are not multi watt compatible please check yours.

    nope,t5 sure go for it but 6 x 54w or 6 x 80 even wont be enough(80w better option though)
    may be able to keep some softies but still very underlit.

    If you want to keep anemones,hard corals etc i suggest at least 8 or 10 x 80w t5's

    if you go 54w then atleast 14 which will be costly hence i suggest mh or 80w t5 as better options
