sand

[akumanohi]

hey guys and expertise, i have a question for u all, erm... my tank is abt a mth plus abt to 2 mths,i realise that the coral sand and chips at the base starts to turns brown and dirty which leads to my bottom of my glass, is it ok to leave it or wad? pls gif advise~ thanxk

[vincegoh]

I think that is normal. Soon u will have coraline aglae.

[Achilles Tang]

Is it a light dusty covering of brown or thick maroon matty covering with oxygen bubbles in them?

The former will be diatoms.... once they finish the silicates in your water, they should die out.

The latter will be cyanobacteria... that one is harder to get rid of and usually indicates a high amount of dissolved organics & phosphates in your water.

The use of GAC and Rowaphos should help a lot for both.

[vincegoh]

Since his tank is still very new, I don't think there will be so much nutrients to have cyanobacteria, right?

U means the diatoms will disappear after some time?

By the way, I heard from a friend that by using a DSB, after few years, it will normally crash and acts as a nutrient tank hence usually cyanobacteria will apear. Is it true?

[Achilles Tang]

His 2 or 3 month old tank is probably stocked up already. We don't know what he has inside nor do we know how efficient is his biological filtration setup nor his equipment setup.

All this will affect the level of dissolved nutrients in this tank... and the appearance of diatoms or cyano or dinoflagalletes will signal that they are 'feasting' on it.

Simply - remove the 'fuel'... and they will go away.

Still debatable. Too few cases happening to panic yet. There are 15 year old DSBs around. Anywway... DSB or Liverock... these will absorb heavy metals from the saltmix and additives we put into our reef tanks... so a crash may be coming your way...maybe.

wad do u guys mean by GAC and DSB? i'm realli dunno wad do u guys mean, maybe its too 'chim' to mi liaoz~

[anakjoh]

GAC - granulated activated carbon

DSB - dead sand bed

The abbrev.'s in the pinned thread. You shld read it first. For eg. LR - live rock.

Here's the link

[akumanohi]

ya i noe, so wads does dead sea bed means? is it bad or wad? and the GAC is a normal carbon? izzit?

[Achilles Tang]

LOL! I think he meant Deep Sand Bed.. not Dead Sand Bed!!

GAC is not the same as ordinary carbon. Its a much higher grade carbon.

[akumanohi]

ar? is it the carbon that comes in a bottle type wan? erm... there got the pic of a clown fish? and wad is deep sand bed? dun realli understand

[Achilles Tang]

Akumanohi.

You really need to read this IMMEDIATELY!!

Don't start a marine tank until you understand everything.

[ben]

deep sand bed is sand at bottom of tank and granulated carbon is finer size of carbn which is better aborbing power

[akumanohi]

hey~ lac lac lac brother AT, i noe i noe. so its gd lahz ya? hehe:) erm... AT, i really wish to get some SPS into my tank but i seldom see it... can u intro mi to some shope which have sell it and also cheap which can have discount? hey ben, thankx for ur explaination... realli appreciate alot... thankx~

Aku,

You're off topic and its quite rude to hijack someone else's thread. You are new to the hobby and inexperienced and have yet to learn about basic reefkeeping. You SHOULD NOT venture into SPS coral keeping because I can guarantee you that you will be killing them and wasting money.

AT

[akumanohi]

ok... sorry AT, but i'm jus trying to giving opinion to the others, is that wrong? okok~ i'll do abt my own probz

[Achilles Tang]

AT, i really wish to get some SPS into my tank but i seldom see it... can u intro mi to some shope which have sell it and also cheap which can have discount?

I was referring to this.

[akumanohi]

u mean this is rude? or is off topic? then where can i post this kinda topic in? and wad u mean in hijacked into others topic? did i?

If aku wants to kill these SPS coral, better might as well give to both of us, hehe

[Achilles Tang]

Yes, my friend, you did.

You should start your own thread.

Imagine if you started a thread talking about apples, and people come in to talk about cars and dogs and aeroplanes?

Understand now?

I will have to delete these past few posts now... more work for the admin.

[akumanohi]

ben, and AT, i realli dun wish to kill corals~ no bodys wanna kill them, they r so beautiful~ i realli like them and wanna try to keep some of them, but u all insisted dun tell mi more abt it and i cant learn more abt it? is it fair?

[akumanohi]

ok, sorry AT sorry for the troublesome. but i realli need to learn other them being corrected and dun teach mi~ pls AT i need to learn from u all and not saying mi that i am killing them~ sounds hurts~
