Zoas are crazy.
Some tanks they grow F A S T
Other tanks you stare at 3 polyps for 3mos

We need to HEAR from the ppl where zoas grow like crazy

We need to know answers to 10 questions (please and thank you):

1) What color of zoa is growing like crazy?

2) Where is it in the tank? Bottom? Middle? Highup?

3) What salt are you using?

4) what's your avg Salinity?

5) How often do you do waterchanges?

6) What lighting are you using? Mostly blue? How much white? How long is your light cycle?

7) Are you dosing anything? If so, what?

8) what are your Nitrites normally? 0? 2? 5? 10+?

9) do you SpotFeed them?

10) any hidden tips or tricks you want to share?


.I believe some undiscovered facts are out there to be found on what's going on with people's tank where zoas are going like Aiptasia.

There has to be some common factors that are not connected for a lot of us.

I'm staying on this post to get a hearty 40+ responses

Following along. We have a few zoas that grow pretty good.

Salt - regular IO
Salinity- 1.025/35 ppt
Alkalinity - I try for high 8's
Magnesium- after water changes is around 1600 ppm and drops to around 1440 ppm prior to next water change
Calcium - after water changes is around 500 ppm. I don't dose calcium until it drops to 400 ppm
Phosphate was always around 0.1 ppm until I started using a macroalgea reactor
Nitrates were always around 20 ppm until the macroalgea reactor, not they are stable at 5 ppm
Temp - 78°F

Most are in moderate flow and between 100 - 200 PAR mostly.

I am dosing Quantum's Bio-color Enhancer line along with phytoplankton and Zooplankton.

I fragged those zoas from my parents reef tank, put them in my new tank in October. There were maybe 5 polyps. This is it now with water parameters and light settings on my fluval sea 3.0

I dose 20 ml of 2 part twice a week and 1 drop of lugols once a week. It’s a 75g tank. Salinity is 1.025, temp 78. 20% water changes bi weekly. I feed benepets reef food twice a week. Flow is just one tunze powerhead and the return.

Zoanthids are what made me want to start this hobby to begin with!

Nitrates: 5-15ppm
Phosphate: 0.5-1.0
Salinity: 1.026
Temp: 76
Calcium: 400-420ppm
PH: 7.8

I broadcast feed twice a week with reefroids and reef fuel. Daily feeding with phytoplankton.

These are near middle in the tank. I use reef crystals but have moved away from doing water changes. Alk 8, calcium 410, mg 1280, don’t test nitrates or phosphate. Tank gets reef frenzy 2x a day. Dosing big 3 as needed to keep targets. No spot feeding anything. Light is a reefbreeders photon v1, can’t remember full cycle but white and blues both peak at 100. Zoas grow decent for me though some def are slow or stagnant.
some other colonies I have.

How much flow is good For them? A direct blast periodically or a lower flow? What is better to get good growth?
Mine seem to appreciate good, but indirect, flow. Between my return, 2 Tunze powerheads, and gyre, my tank peaks at around 3k gph in flow.
 

Do you think "petting your fish" is a good or bad idea?
