reef Posted September 8, 2004 Author Report Share Posted September 8, 2004 not so sure it is the light. my nitrates are almost zero know down from 2ppm and phostphates are zero down from .001ppm also since adding reef solution all my acros are open all the time and the xenia is finally growing very well.

Doc Holiday Posted September 8, 2004 Report Share Posted September 8, 2004 What kelvin rating are the new halides? They seem to be alot higher than the previous, this can make things look like they have changed colour a whole lot more. Quote Link to comment Share on other sites More sharing options...

reef Posted September 23, 2004 Author Report Share Posted September 23, 2004 What kelvin rating are the new halides? They seem to be alot higher than the previous, this can make things look like they have changed colour a whole lot more. I use 14000k bulbs with t5s, This is unlikly caused my coral to change colours as they were changing colour previuosly under 14000k 250w bulbs, some ohotos are more blue because they have the t5s going. without t5s i get better photos.

Pies Posted September 23, 2004 Report Share Posted September 23, 2004 Reef has been using Zeovit, just keeping it quiet... Its the lights Quote Link to comment Share on other sites More sharing options...
reef Posted September 23, 2004 Author Report Share Posted September 23, 2004 Reef has been using Zeovit, just keeping it quiet Right, Have not got time to add acid to my tank daily. Colour change is caused by low nitrates and phostphates. The addition of reef solution from ecosystem has also made the differance due to the minerals and iron in it. Nothing to do with lighting. just a fad. I run a quarantine facility and i see how the true colour of corals are when they arrive. after 2-3 weeks there is dramatic colour change to a more brownie colour due to the high nitates in the system. The acropora tank also has 400w and the corals still go brown. Quote Link to comment Share on other sites More sharing options...
