Hi guys, I'm setting up a frag tank and want to make sure I'm missing anything. It's only approx 30L with a heater and powerhead. The light is an aquaray tile. How often should I do a water change so it doesn't get too polluted? Do zoa need nitrates? Or would reguar dosing of nopox help, particularly to prevent phosphate and hair algae? Would you do an 8 hour light setting- 1 hour eitherside blue and the remaining 6 white? Are there any other lights you would recommend? Would you put any live rock in there too? I've left some in my main tank which have hydras on and they are all open and lovely. I'm hoping the zoas in the new tank open up soon too! Sent from my SM-N950F using Tapatalk

Im also looking at setting up a zoa frag tank but will be using an old 90l QT tank that i have, 30L sounds like a good size however i would look at adding an internal power filter you can get nano ones and that will provide your mechanical filtration. As for water changes you could perform 10% weekly or with no bioload as in fish you wont need to to export nutrients unless your not dosing and relying on water changes for elements. Zoas do like nutrient rich water however but you could use no pox to keep it stable does work well for nitrates. You could put some rock from your DT in your frag tank as that will help with biological filtration but if your fishless then theres no real need i would suggest adding a 6 line wrasse in as that will control any pests and possibly a algae blenny to keep on top of algae.
