Zoa polyps not growing...

[Scottrshoe]

These Whammin Watermelons have doubled the number of heads since I put them in the tank, but heads are all still pretty small...water parameters play into this as well as coloration?

They tend to color up or look meh depending on different factors like light, nitrates, phosphates, etc. Basically an experiment in your own tank since everybody’s tank is different. I have seen good growth and coloration in the from below 0.1 phosphates and 2-10 nitrates.

So lighting,flow,nutrients and trace elements all contribute to zoa head size and growth.

I had a problem with keeping nutrients in my pico (maybe because I used live rock,MB7 and pods to seed the tank),but no matter what I did nitrates and phosphates would never stick around.

So I dosed NeoPhos,NeoNitro and my dull z/p's colored up to how they should be,started to grow super fast and their polyp sizes went from the size of a pencil eraser to a dime within a few weeks.

Iodide REALLY helps z/p's but you need to be SUPER CAREFUL when dosing this element and any rule of thumb is whatever you dose (trace element wise) you need to test for.

Low actually p04 .02+/- .01& n03 is around 5 -10

Is the rubidium to blame....idk maybe
