Newbie on saltwater (White web on LR)

[nyaherkz]

hi RP! Mga master super newbie here on saltwater setup..I have a 75 gal dt and 50 gal sump. 4 days p lng ng cycycle ang tank ko, wala pa ako filter media sa sump. Live rocks and sand pa lang laman ng dt. Don't have any good lighting yet. Bibili pa lang din ako ng test kit. Hydrometer pa lang meron ako. 3rd day ng cycling meron ako napansin na white web looking sa live rock ko, pabayaan ko lang ba or need to remove it immediately? What is the cause of that web looking thing? I'll take a picture, kailangan ko muna pag aralan kung pano hahaha. Thanks in advance mga boss!

puede na iwan yan...IMO..

nasa cycling pa naman sis

[nyaherkz]

ano po kaya sya? at ano po kaya ang cause?

[seth]

die-off. Dead/decaying organic material. Could be decaying sponges or algae.

[nyaherkz]

Do I need to remove it?..Thanks guys!

[seth]

you could just leave it alone. but it would be good to remove it. bawas kalat at excess nutrients yan sa tank.

[nyaherkz]

what will happen if I remove it?, or If I left it there?. super noob ng mga questions sorry. Just want to know kasi ayaw ko na sana muna galawin yung tank kasi cycling stage pa lang.

[aldwin]

sabi nga ni sir seth, extra kalat sa tank...

at extra nutrients din...

maaring mas tatagal ang cycling...

[seth]

What aldwin said. Basically, the more crap you put in during cycling, the more crap you have to remove when ammonia and nitrite drop. Having too much ammonia (more than 1 ppm) even impedes the cycling process, asthe turnover becomes slower. And then there's that PITA redfield ratio.

Anyways, if memory serves me right

For every 1ppm ammonia you have in your tank, you will end up having

2.7ppm nitrite then 3.6 (or 3.64? Sorry I forgot the chemistry behind this) ppm of nitrate. That explains why most beginning aquarists end up having nitrate levels that are way off the charts.

woooohooo nosebleed! hahahaha pero ok po mga master salamat sa tulong. I'll remove it today, last question na mga boss. Bakit po kaya sila namatay? Eh nababad ko nman aga yung LR and 3 days bago lumitaw yung white webs?, ano po kaya naging cause?. para next time na bibili ako ng LR alam ko na gagawin. thanks in advance mga boss!

[aldwin]

try mo kaya muna hawakan?

baka buhay yan bro?

Normal talaga magka die-off, kasi una pa lang inalis sila sa dagat at naexpose ng ilang oras sa hangin ng walang tubig. Tapos malalagay sa holding tank na marumi then papunta sa tank mo... normal course yan kapag gumamit ka ng liverock. Yang mga puti na yan malamang talaga na sponges yan na namatay dahil naexpose sa hangin. Maraming nangyayari during cycling hindi lang yung paglabas ng ammonia at pagconvert nito sa nitrites then nitrates.

Para may clearer picture ka, ganito ang nangyayari kapag nagcycle ka ng LR na maraming die-off:

Andyan yung pagbagsak ng pH dahil sa die-off at sa pagdami ng bacteria (CO2 production), pagbagsak ng oxygen levels, pagbagsak ng redox potential, pag swing sa alkalinity (dahil sa pagtaas ng CO2 at pagbaba ng pH) pagrelease ng toxins at secondary metabolites ng mga decaying sponges and algae na nasa liverock which in turn, makakapatay din lalo sa iba pang organisms na nasa rocks - bacteria and microfauna like worms, etc. Kumbaga domino effect. After nun saka unti-unting mag-stabilize yung system at tatama yung parameters with exception to nutrients, typically sobrang taas ng nitrate at phosphate dahil sa die-off at sa pag leach ng phosphates na galing sa mga bato..

Anyway, again maraming schools-of-thought sa cycling lalo na at marami rin kasi ang options mo sa tank (liverock, diy rocks, base rocks, etc). Marami dito proponent ng paggamit bg LR at iwanan lang yung decaying matter at wag mag water change during cycling (okay naman, pero para sa akin may mas efficient means to cycle) para sa akin counter-productive kasi yun dahil mas pinapatay mo yung beneficial microfauna na nasa LR, like worms and pods (na sila rin ang mismong dahilan bakit ka nag LR in the first place, lol)... at dadami pa yung trabaho mo after ng initial cycle dahil sa nutrients na naiwan sa tubig. More nutrients = more algae.

So ayan din yung sagot sa kung paano mababawasan o maiiwasan ang sobrang daming die-off during cycling. At paano maiiwasan ang grabeng algae infestation pag tumagal.

Mas maganda yung paliwanag diyan sa article na pibost ni chonglai sa "curing liverocks" thread.

Sobrang salamat sa info master seth! Atleast now I understand na the process.

[aldwin]

ayan...pati ako nag ka idea uli hahahahaha
