Hi guys,
I have a T5 Juwel light unit over the Rio 180, and I'm getting a bit of BBA. I cannot do anything about the light. It is 90w across 2 tubes and it won't work with just one illuminated. It's only on for 6 hours a day and I cannot get any lower wattage bulbs.
I dose EI using this calculator http://blog.fluidsensoronline.com/calculators/estimative-index/ based on 140 litres due to substrate and wood etc.
I inject CO2 for 7 hours, (4 hours before lights on through an external reactor) up to my drop checker shows lime green/yellow.
Flow wise I have a JBL e1501 firing out of the spray bar across the middle back wall. Either side I have a Koralia Nano 900. So in total 3200 lph flow.
I have BBA on the edges of the bogwood I have and on some lead edges, especially anubias nana, green spot algae just above the substrate about a cm high, and green dust algae that easily comes off with a magnetic scraper.
What am I doing wrong? Or what can I do to sort the algae issues. Can I increase EI slightly to compensate for the high light? Do I need more CO2 in there? Or do I need more flow?
Any help appreciated guys, its doing my head in now.
