My parameters are good except nitrates. 15-20. I purchased a complete system from a guy and I believe by using the existing substrate I have started the cycle again. I have a blue neon damsel, two clowns, sailfin tang, lawn mower blenny and a blue green chromis. Lights are a six bulb t5ho setup and I have my moon lights on from 11 am to midnight. Actinic from 12-10 and full lighting is from 1-9. I have added a hydor koralia smartwave controller with one 1050gph head and one 550 gph head and an rp3 wet dry filter which has an overflow box which skims the surface. Hopefully this gives everyone a good idea of what is going on in the system and if I should be doing anything or if it is running a natural course and this white will be covered with a good algae in time. Thanks for all of your help.
