here is pretty much dead.

Thats the thing about live rock, you never really know how long its been sitting in the LFS. But there's gonna be some die off regardless of how fresh it is. By rinsing it in freshwater and sunning it you kill of the most valuable part of live rock - the myriad of sponges, corals, algaes (coralline algae) and bacteria that may have been inhabiting the rock. Its dead rock now.

Have you put the new rock in your system? What are your water parameters after putting them in?

thx i'll check that out later
yeah the LFS here only 1 carry live rocks and it smells bad too, meaning lots of things died off already
plan to start all over, so had to turn it into dead rock first (too bad killed all the things that was in there before)
got few crabs, clams and one worm i think which got toasted in the sun..
actually the rock was very very dirty, when i cleaned it in freshwater, lots of things came out plus debris etc, smell much better now but i want it to be really clean so leaving it in the sun again for few more days
haven't put in the rocks yet so haven't tested the parameters for now
Later will test before but i don't think there will be much spike if i put it in cos the rocks are really dried out now
i'll post something about it when ready

Corals not making it is largely due to water parameters - the stability or the lack of it. Whether SPS or LPS, corals need a constant balance of (as low as possible) nitrates, sufficient lighting and filter feeding. Calcium and Magnesium play a vital role to the vitality of corals as well.

When a coral starts to look bad, there has to be a parameter or two lacking. Test for Am, No2, No3, Phos, Cal, Mag, dKH and PH. Some dose Cal & Mag (2 part dosing), but to me, a constant and religious weekly water change should do the trick for depleted elements! If the tank is stable enough (attributed from test results of test kits), monthly water changes should do it.

I have since found that no matter the brand of product, it all comes down to water params. You can't go wrong with it, unless the test kits are faulty/expired.

Exposure to sun light is interesting. Corals out in the ocean have natural sun light but in our closed-loop aquariums, sun light = potential for algae growth is much higher. The timing of the exposure is almost going to be non-consistent since sun light is not constant all the time (rainy days, sunny days, cloudy, etc.) And surely there has to be a better way since sun light on aquarium glass/acrylic = as you said, heat it, potentially a disastrous consequence in the making in the months to come.


By doing so the rocks essentially are 'dry rocks' instead of live rock. Not a bad thing, but you lose potentially some beneficial bacteria and some critters that go along with it. Doing this would also mean a less 'dirty' looking tank since it has been rinsed thoroughly and die-offs probably got rinsed away as well.

I would recommend cycling your tank with bacterial additives. The most effective (and proven to work) based on feedback:

- Tetra SafeStart
- Dr. Tim's One & Only
- Instant Ocean Bio-Spira
- Microbe-Lift Special Blend/Nite Out II

The above contain the 'exact' bacteria needed - Nitrosomonas and Nitrobacter. It will take from 1 - 2 weeks to cycle, for the bacteria to grow on your substrate of choice (sand bed, filter media, heck even the sides of the glass plane). You need to add ammonia to "feed" these bacteria - a good and clean source would be mysis shrimp (e.g. Hikari Mysis Shrimp). Drop a cube or two into the tank and let it be. Ammonia and Nitrites would peak in first week, and drop in the next. Once Am and No2 are zero, do a water change = 30-50%. The cycling is then over.

thx for the advise
that's exactly what i did as well. I've put my live rocks into my tank already after making sure i could clean it as much as possible. The next day after i put in, nitrate spikes real high and i went to get the bacteria solution (bio bacto i think) and put in the required dosage. Then I had a work trip for around 8 days and when I'm back, diatom started to bloom already but not that much.
When i tested again on the Nitrate, the cycle has totally completed but I still put in the bacteria solution right now
next is i'm trying to order some clean up crew and tries to clean up the diatom plus other algae that may surface later
Only manage to get some red onion nerite snails which will come in few days time. but dang, i can't get any cleaning crew from the LFS here... had to order the snails from one guy selling here.
All seems to be just nice right now

guys, did anyone use food grade Epsom salt from guradian/watson as reef tank magnesium supply.

I was shock when I found a pack of Epsom salt from guardian is just RM 5.7 (food grade pure magnesium sulfate)
while I have a small bottle of magnesium supply cost RM35. the magnesium crystal shape and chemical labeled on both box is identical...

I have my DIY LED for reef ... and my coral still kicking after 1 year.
the problem is getting the right wave length LED which is hard.

I dont know what is the ppm abses on my testing.

I having the same tester lol, I am guessing it is the 2nd one.... did u clean your test tube after test?

You have to use saltwater test kit from API and not freshwater.

Which shop do you go to for marines?

@calvinyoon

The safest way is to wait one month for it to mature. Liquid measurements are a guide only. For example they cannot tell if the newly bought artificial sea salt is of a bad batch or not.









As to live rocks, I still go for fresh live rocks that has been filtered for a few days such as Aquatics International. I do not have faith in barren looking live rocks.


I still think a successful marine tank requires a good current flow and surface skimming as part of water changes.


Having some window light helps as long as you got a good balance of living specimens inside.


I have some Caulerpa, Chaetomorpha, Halimeda and many snails. My blue tangs, green wrasse, etc do not disturb any of them as they prefer softer algae and the Hikari pellets.

Wanna Sell this auto top off system to maintain water level in saltwater aquarium automatically ..... RM249
u can buy from here Buy from lelong

hi guys ~ if you guys wanted to buy any salt water aquarium stuff can come here ~

Does anyone want to sell their aquarium?

Hi, Have you bought your aquarium? I'm selling mine.

Hi All,

I'm looking to sell my aquarium set. Most importantly I want to sell my live rock. I have about 30+kg of live rock still in salt water. I'm selling it off way much cheaper than what you get outside and you can immediately add it into your tank. Who ever is interested can PM me.

Hi all, I am looking for any individual or company who does professional aquarium rental service for salt water fishes and corals..any one here know of any contacts? Please let me knowwwwwwwww. Greatly appreciated! Thank you, gracias, merci, arigato, kamsahamnida!!

... wonder anybody here know if this saltwater snail is poisonous and the species of this snail ... thanks in advance ... ...

Harmless turbo snail. Good algae eater
