Hello,
Just like the subject says I need advice on my sump setup which currently have chaeto on top of deep sand bed of 4''. My setupis due to lighting requirements of chaeto, I have put lights there and im happy to say that the chaeto is slowly growing. But due to the constant lighting the sand and glass has become dirty due to brown algae? So what can I do? does that mean that I need to remove the chaeto and light or remove deep sand bed so I wont have this problem?
Your expert advice is highly appreciated
