Zoa problem

[richardhao]

Guys my zoas specially the bambams turns pale and are always half open.

My water parameters are: (all tested using API test kits)
NO3 : 5ppm
PO4 : undetectable
Alk : 8
Ph : 8.2
CA : 420

Dont have a Mag tester.

I'm using leds, and they have been in that place ever since.

Light intensity maximum was Ch1 55 Ch2 50

And my live rocks are full of the dark maroon-like algae, dont know if its macro but its a nuisance since the zoas dont spread over them, are these Dinos? they are not slimy and has a carpet-like texture when touched.

Sounds like Cynobacteria... may water flow issues ka ba? like may mga parts na mahina flow?

[richardhao]

wala naman problem sa flow, may 2 wavemaker ako sa tank.

chard try mo idip yung rocks with zoas mo sa hydrogen peroxide yun blue 20volumes mga 3 to 5mins max then wait mo na lang for a couple of days magopen up ulit sila and algae gone minsan talaga pag may algae parang irritable mga zoas hehe HTH

[actino]

Ano ito?

"hydrogen peroxide yun blue 20volumes"

Alam ko ang hydrogen peroxide pero ano yun blue 20 volumes?

Thanks.

[potring]

bro actino yun blue labeled bottle mas matapang sya compare sa red labeled bottle dalawa kasi yan, not sure kung ilang volumes yung red bottle coz ang gamit ko is blue and nakalagay sa bottle nya 20 volumes, now ang ratio is 1 cup of hydro perox blue mix sa 10 cups of NSW ng tank mo, after madip mo na zoas, rinse it and soak it first sa new nsw then back sa DT, got it bro actino

[richardhao]

ay sus kakabasa ko lang ng post mo henry, kakatapos ko lang sila idip sa revive. may sinuka silang kulay itim or dark brown eh, dont know kung ano mga yun. pano ba tanggalin cyano? alam ko sa cyano sa sand di ba?

[potring]

hahaha oks lang yan give them a week muna then idip mo ulit, and re cyano kahit sa rocks tumutubo mga yan and kung hindi nakafix rockscape mo idip mo din sa hydrogen mawawala yan 100% hehe, kaya siguro nagkaron ka ng cyano nag semi cycle tank mo eventually mawawala din mga yan kaso itreat mo zoas mo then from time to time linisin mo rocks nila like toothbrush para matanggal mga algaes and mas lamangan mo muna sa blues yung led mo kung pwede nga wala muna whites para mawala algaes mo, well it works for me but not sure if others will

[potring]

ayy nakalimutan ko yung sinasabi mo na sumusuka na brown or black parang waste nila or pupu yan hehehe natural lang yan they do that sometimes

[actino]

Got it Potring. Thanks.

[richardhao]

Actually hindi sila humahaba dahil tinutuka ni dory at ng tomini tang. I think i have to dip my whole rockscape... Hay.. Kalat na kc.. Or start from scratch ulit

[seth]

not cyano, probably red turf algae. seems like you have water quality issues judging from the looks of the zoas.

[richardhao]

If water quality what could be the problem? Other zoas are doing fine.

[seth]

if turf algae is growing fast in your tank, that may be your biggest problem (nutrients are an issue, even if they register zero in your testkits) IME turf algae can easily kill corals, by allelopathy or just even by overgrowth.. even corallimorpharians and zoanthids are vulnerable.Best thing to do is find a way to eliminate it, and WCs will definitely help as well. Detritus may also promote more algar growth.
