Hi,
I just bought a 55 gallon tank and I am planning on keeping 3 baby red ear sliders in it. I am going to order a rena xp3 filter, exo terra turtle pebbles and a large exo terra bank for basking ( Although I am open to suggestions if something better is out there within similar price range I would totally go for it please let me know )I am a little confused with the lighting. I am trying to spend less but not compromise too much on the quality. I have a big tube light on the top of my tank, I don't know what kind it is since the person I bought it from had it on from before but would it be okay if I just replaced that light with a uvb/uva light? or do I have to get something that would go directly over the basking area, I believe the tube light does go over the whole tank but I am not sure if It would focus as required for basking. Secondly if this is possible then where would I get a light that would fit the tube section and would be a dual uvb and uva? IF not then what are other good economic options for lighting ( lamps and bulbs ).
All replies will be appreciated. Thank you very much!
