SRC Member Randy Posted March 22, 2009 SRC Member Share Posted March 22, 2009 Hi i have a 4x2x 2,5 height fish tank, using 2 blue 2 white T5 lights. When I on them all, the effect is rather yellow white effect. However I have seen smaller tanks like 2 or 1.5 height using 2 blue 2 white T5, it was rather shiny blue effect. Why is there differences? Could it be the height diff or the brand of lights? I am using only hopar t5 lights fyi. Any advise is appreciated. Thanks.

SRC Member Randy Posted March 22, 2009 Author SRC Member Share Posted March 22, 2009 sounds like your tubes problem? or its ur water yellowish? u tried using just blue or just white? i.e switching on the white lights only. if only white , even more yellowish. hmm my water may not be so yellowish..though i add normal amount of iodine weekly as instructed. if i turn only blue. its pretty dim...i thought height of tank might be the problem that i need stronger light...

VelvetAirwaves Posted March 24, 2009 Share Posted March 24, 2009 what colour is your sand? gravel usually reflects the light , might wanna check out the substrate , yellow colour then you'll get a yellowish environment. Quote Link to comment Share on other sites More sharing options...
hammy Posted March 24, 2009 Share Posted March 24, 2009 to check whether ur water is yellowish, put some water in some testtube like those from salifert for testing water parameter and put it against a white paper. u will have ur ans whether ur water is yellowish =) Quote 2x1.5x1.5 tank Lighting: AI hydra 52HD Skimmer: Deltec SC 1455 Reactor: Minimax; rowaphos Skimz ; NP biopellets Wave Maker: MP 40 WQD Return pump: Eheim 1262 Chiller: Arctica 1/10 hp A righteous man cares for the needs of his animal, but the kindest acts of the wicked are cruel -- Proverbs 12:10 Link to comment Share on other sites More sharing options...

SRC Member Nitro Posted March 24, 2009 SRC Member Share Posted March 24, 2009 Hi Randy > What brand of T-5 r u using and for the white T-5, what colour grade isit? As in Aquablue+ or a normal daylight T-5. For Aquablue+ (the tube that combines blue and white colour grade), brands such as D&D or Deltec does give better colouration.

boxerz Posted March 25, 2009 Share Posted March 25, 2009 in fact my sand has lots of debris and i would say most probably is slightly yellowish in color...could be the reason I suggest you do not stir your sand because it can create a mini cycle.

SRC Member Morpheous Posted March 25, 2009 SRC Member Share Posted March 25, 2009 What is the temperature of the tubes u are using? 6500K or 10000K or 20000K ? How long have they been in use? Tubes tends to have spectrum shift after a period of use.
