Haha...I wanna come too!! Want to get to know more ppl from the club!!

NO

Hey I didn't even know excel can plot graph, so I am in the age where there is only cyano?

Haha...we go find whose place the biggest and we hold frag meeting there la Too bad my SPS are all frags or else I can exchange with you guys

Oh I know what you guys are talking about You mean the RSB had come back using another nick? Man, that's disgraceful

Have you guys gone bonkers???!!!

Ok here's what I am going to get this weekend 1) DE's MH rack 2) Amino Acid supplement 3) Aquaz Carbon 4) Salifert Alkalinity test kit 5) Mystery fish 6) Some SPS frags (if some bros are fragging pls PM me!!!)

The signature too big Anyway, why don't do one of your zoos?

Too big la bro. Anyway, take really good care of the powder black. Do not take chances when it is infected with ich

Black substance in sandbeds I am definately sure that any aquarists who have kept sandbeds before would have come across the statement that a black layer would be formed. Some say this is hydrogen sulphide, some say this is cyanobacteria. Actually, this black stuff is none other than FeS or Iron sulphide. Iron sulphide itself is a brown precipitate and due to the intense colour, we often perceive it as black. All sulphides are toxic to organisms and thus, this chemical is not good for reefs. This compound is formed by sulphate reducers which being anaerobic bacteria, usually thrive under mats of the cyanobacterium Lyngbya sp. or in any anaerobic region. Thus, in anaerobic regions of sandbeds, a "black" layer of FeS is formed. FeS can be oxidised in the sediment by MnO2 or maganese oxide into FeOOH, S, Mn and H2O. It can also be oxidised into sulphuric acid by autotrophic or mixotrophic bacteria and will be neutralised by calcium carbonate into calcium sulphate. All in all, the black substance is not much of a worry BUT it indicates that the sandbed has a totally anaerobic zone and this should be the main worry of aquarists

I got no choice, since the surface of my current one is dirty Make me so worried that I thought something had happened to my tank

Well, seems like I got to go get another cleaner

wah your chevron sure loves to poop anyway, nice SPS

The true nature of SPS reefers

Come join the beckett club

no, you should run it for 24/7 Good designed recirculating models will give you near neutral pH effluent

Another different species of monti

Well if you count the branches, it has exactly five!!! Just like fingers It had encrusted on the rock and new growths are forming at the base

Where's roidan? We need his super foaming knowledge as part of Intelligence

Yes the leather is not advisable for ppl keeping SPS More for ppl who are into softies only BTW, my perculas got to find a new host soon

For those with magnetic cleaners, does your outer glass get stains when you clean it? (ironic right?)

If I can remember, AT had bought those velvet slugs before Slugs vs Worms?

Tell you guys something I found out why the water cloudy Guess what, I was sitting on the floor watching the tank and noticed that the glass had marks. Went to clean the glass with vinegar and glass polish and water is crystal clear again. Can't believe I fell for such a stupid mistake!!! Thanks anyway bro Vincent, would take note of precipitation due to ionic imbalance

Follow up on black sunstance in sandbeds will be posted on Saturday Stay tuned

Haha...here's my orange polyped digitata and blue polyped purple digitata
