Ok – with that being said….follow the advice above. Do a search for “coil denitrifier” and consider a simple 5 gallon bucket refugium. These are two VERY cheap solutions. If you choose to set up a refugium I will mail you 3 kinds of macro algea’s – shipping is on me. I am very short on time (at work) – but if interested post here and someone will tell you exactly how to set up a cheap DIY refugium using a 5 gallon bucket. PM me when you are ready and I will send you macro’s.
