Upz still far from filling the tank~ thanks for all the kind offers that were made. appreciate it!

Couldn't reply all that offered but thanks all for the offers, i am still looking for bio media to fill my 1tonne filter (marine pond). live rocks offers are welcome (not looking for aesthetic rocks) anyone know of wholesaler in aquaculture/aquarium supplies? PM me~ Thanks in advance

upz any form of Bio filter/media are welcome.

Hi guys, anyone know where i can get AquaCare Algae Medium in Singapore? i would like to cultivate some nannochloropsis Thanks~

Hi Guys, i read on the net that we could use Sodium Bicarbonate and carbonate to increase our KH. http://web.archive.org/web/20021127040526/http://www.advancedaquarist.com/issues/nov2002/chem.htm Bicarbonate and carbonate are used in different PH values. my question is, if corals use bicarbonate to make their shell(carbonate) shouldn't we be dosing bicarbonate instead of carbonate?

great ideas and improvements. think i'm gonna try this!
-
manage to revive the algae, but i now worry its the wrong algae coz this batch seem rather hardy. it has remained at its peak for like a week now and no sign of crashing. i have read online somewhere (tried to revisit the site but couln't find it) that nannochloropsis could mutate into some other cell which are more hardy. Any idea how can i spot if the algae has changed?

Salinity and other water elements
Koonitdo replied to Koonitdo's topic in New to the Marine Aquaria Hobby
cool, i might have to consider a RO/DI unit then. seems like its pretty costly to keep purchasing water from stores (imagine the cartons i got to carry ><) on the topic of heavy metals, what are the effect of them on corals anyway? btw RO/DI units need not be run 24 hrs right? they can be used only when required? Is there a volume capacity tied to spec of the RO/DI unit? it seems like they usually only specify a GPD rate and a TDS has to be used to determine if the contents has to be changed out. please correct me if im wrong here. anyone has a gauge on the volume of water produced for a ZERO 5stage RO/DI unit can produce before the content need to be changed out? http://www.madpetz.com.sg/index.php?main_page=product_info&cPath=&products_id=395 apologies for tonnes of question. getting really excited on starting this new reef hobby. -
Salinity and other water elements
Koonitdo replied to Koonitdo's topic in New to the Marine Aquaria Hobby
that clears up the mist. i have a large koi pond actually, was wondering if i could use the water from there to top up instead of buying RO/DI water. but since koi ponds can be considered aged freshwater? there will still be trances of silicates, phosphates and other dissolved organics? -
Salinity and other water elements

i'm doing a reef tank. I am still in the midst of cycling the water still. what is "aged" freshwater? is there a benefit to use RO/DI instead of dechlorinated tap water? Where do you get RO/DI water? mineral bottles? Thanks for the help so far -
Hi All, i currently have a 4ft tank uncovered and close to the window. its pretty hot in the area. i read around and evaporation would cause me to top up about 4L/day? my real concern here is the top up of fresh water would help maintain my salinity but wouldn't it affect other parameters too like PH, Calcium, KH since topping up fresh water would dillute the solution. Thanks in advance

i went to drip more f/2 into the water and it seems to be getting better but very very slowly. some other possible causes i could think of is that i did not dechlorine my tap water when i was diluting the seawater to achieve 1.020 in salinity. the density was really thick when i split them. maybe i did not split it during the exponential phase of the bloom. but i would try splitting it 50-50 in the future. algae culture seems so tough ><
-
The Seawater is filtered thru a 5 micron sieve, and microwaved for 3 mins. i always have this problem when i split my culture. it would start to grow denser when i combine 2 failed culture together. i was wondering if it is due to the lack of f/2? bawater was suggesting 1ml of f/2 for every liter of sea water. i drip only 1.45ml of f/2 per 3.78L of seawater.

Hi all, I realise that my nannochloropsis culture keep turning yellowish everytime i split a dense culture. i believe it will crash in the next 2 days. what have i done wrong? i had used 1/3 of dense culture with 2/3 new clean seawater. added 1ml of f/2 for every new liter of seawater. i had sterilize the container as well as the new seawater by microwaving them for 3 mins. lighting is provided 16hrs and 8 hrs darkness. culture is placed under shelter away from the heat as well. can anyone point out my mistake? or advise how to correctly split my cultures? thanks in advance! picture attached is after 24 hrs from split. a yellowish color was observed. the second picture is more severe

Hi All, Newbie here, Would like some help to clarify the difference between the 2. Thanks in advance!

Hi, know this post come way late but where can I get Florida Farm Micro Algae Grow f/2 in SG? I also need some starter culture (nanochloropsis) as Well. Appreciate the help! Thanks~
