Thanks guys, I just need to work out now why the zoas aren't doing REALLY well.
They are very slowly shrinking, I do dose a couple of squirts a day Easy Booster Nano 9, it does say 0.25ml per 25L of water initially, then up to 1ml per 25ml, but I've been scared to add too much bio load too quickly.
Occasionally I mix up some reef roids and turkey baste the zoas, but what else should I be doing?
Remember guys that this DT has been fallow for around 90 days now and despite ghost feeding occasionally there's been little bio load, I'm starting from scratch to a large degree.
