Max...thanks for the possible id, i'll look into that a bit more. As for reducing nitrates, I can't detect any so not sure what to do there. I run CPE, do 10% water changes every week and feed 1/2 cube of frozen food per day.
Glenn...I have heard mixed reports about the Tech M dosing but most times it seems to work. I have mine at 1560 at the moment and pulled a heap of bryopsis out at the weekend. I'll keep you informed.
Terry...I'm not sure if the unknown is hard or not. I'll investigate it when I get home tonight. As for my Foxface, he used to pick at the bryopsis but now he won't look at it, even though I have thinned it out. Maybe I feed him too much nori

Shon...hope you like the band
It never rains but it pours...my No.1 pump has failed now, just a couple of weeks out of warranty. I've emailed the Aussie distributor to see if I can get it replaced so hopefully they'll come to the party. If they don't, what other types of pumps are available that I could fit?
