to think this colour frag is given by the same bro that Down side his tank right

ya there was a time when i switch to PL light and they turn brown after a fews days. as dont have a fan to cool the water so now in my new tank they can be found on the hill below the SPS wating for them to spread on to the pcs of small rocks so i can swop and the main colonel is still growing you wan can swop also me like you love zoos and yumas

yap but always dont have the first hand info on when it coming always found out on net that they have shipment unless u have u let me know also

ya it not zoos but same family right anyway i have palythoas and their tent.is very long ( the one that you going to trade for ) but it is brown under white lights and glow to green under antic. but this it have very short tent. like 2mm so i guess it another species of palythoas

the only red that does well and spreading from my old tank so pls remember to dips every zoos rock you brought if not might end up like me almost half of the zoos gone with the nudis now need to slowly rebuild my zoos tank again looking for those strong colouration zoos

a pink and light blue ona rock

a green ..... dont like this zoo... as it slimy to touch and they spread very fast

slowing colouring up the colour before the nudis attack as it brown now

now these are what i left with today in my new 4ft tank

a sea of yellow only a few left but doing well in new envoirment

so does this

so do this one

this also dint make it either

this also being attack

here are some of my collection of Zoos this die off during a mass nudi attack

you found this at where ?? sg ??? dont think so leh is it from US ??

is your tank height is around 1.5ft ?? and does the melting starts when you change it to your newly brought lights ?? it might because of the mushroom does nt adopt to the new light and start to mel t

first the pic is too big maybe you can try to siphon out the melting mushroom. the fresh that it is melting can siphon out first as it might pollute your tank water. for the rest of the remainding unmelted part might have a chance to recover if you find out whats wrong

can i just get the 250w bulb ?? wat brand and used for how long ?? price

clown fish have the "chao chao" look when they grow older small they are cute but old .......

if i not worng they will leak out some kind of chemicals. for i case i been using the lava rocks for many years in FW. and b4 i use it for salt water i soak it in SW for around 2 mths b4 i use it in my tank moreover i only have a rock just a small fraction of my LR but for ur case you going to use a lot and they are newly brought thus it better not to use it go around the LFS and farm and scout for the LR that are light or dead rock that are sun dry

i did use but just 1 rocks out of so many kg of LR

heehee i myself trying myself in my tank

D.I.Y. Additive Here is a nice little magnesium additive secret, one that I am sure many reef aquarium additive companies don't want you to hear about, Epsom Salt. Yep, the stuff that your grandmother uses for tired muscles, aches, pains and a mild laxative has a use in your reef tank. Epsom Salt, or MgSO4.7H2O, is easily available from the local chemist, pharmacy or drug store (depending on what you call it) and in some cases a supermarket. A half kilogram box should not cost more than a couple of dollars, which sure beats twenty or more for a commercial additive. The dosing rate is simply: to increase the magnesium concentration by 100 ppm, add 1 gram of Epsom Salt per litre of water. As with anything change with the water parameters, take it slowly, and any sensitive corals will soon show effects when things are altered too fast for them. The following is the system that can be use to add magnesium using Epsom Salt. Calculate the total system volume, including tank, sump, and other water containing equipment. Don't forget that rock and sand takes up water volume and that tanks are not filled right to the top. Measure the magnesium level currently of the water, determine what level is being aimed for, and calculate the concentration increase that is required to reach this level. Note that natural sea water has a level of around 1,300 ppm. If the increase required is more than 200 ppm then consider doing the increase in several steps over several days. To obtain the mass of Epsom Salt to add in grams, multiply the system water volume (in litres) by the dosing rate (1 gram per litre), then by the concentration increase (ppm) and divide by 100 (ppm). As an equation this looks like this: Mass Epsom Salt (grams) = 1 (grams/litre) * Water Volume (litre) * Magnesium Concentration Increase (ppm) / 100 (ppm) Weight or measure out the mass of Epsom Salt required. Because this is on a mass basis, either easy access to an accurate weighing scale or an one off access is required. If one is available, then just weigh it out as required. If not, then this be solved by using a small measuring cup, spoon or plastic container and determine how much one measure of Epsom Salt from this weighs. Be careful if the type of Epsom Salt used is changed, as it's density can change and therefore the correct mass will not be measuring out in the future. Take out about a litre of water from the reef tank into a plastic container and add the required mass of Epsom Salt to the water. Stir until it is fully dissolved. Increase or decrease the dissolving water volume as required for the amount to be added. Pour magnesium water into the tank in an area of high water flow and turbulence. This will allow it to be mixed in rapidly with the water. In front of a pump outlet or inlet is a good place for this. Avoid pouring into areas where it will come into contact with corals, invertebrate etc before mixing in correctly. If a over 200 ppm concentration increase is required, then wait until the next day before adding the next amount. Test the water several hours later, if not the next day, to check the magnesium level. Note that it is not a good idea to check it straight away, as it takes time for it to mix in and equilibrate. But will using this type of additive could cause any long-term effects or problems? Note that the magnesium exists as a sulphate salt in Epsom Salt, in a one to one ratio. If Epsom Salt is added to the water to increase the magnesium levels then there will also be an increase in the sulphate levels. To determine if this will be much of a problem, the various species concentrations in natural water have to be considered: Magnesium, Mg = 1,300 ppm Sulphur, S = 900 ppm Chlorine, Cl = 19,500 ppm By a rough approximation, it can be assume that all the sulphur present is found as sulphate, SO42-. Note that both the magnesium and sulphate exist in comparative concentrations, around 1,000 ppm. Therefore for a given increase in the magnesium concentration achieved by using Epsom Salt, a comparative increase in the sulphate concentration will also occur. In contrast if the magnesium additive magnesium chloride (MgCl2) is used the effect will be smaller. This results from the factor of fifteen higher concentration of chloride over that of magnesium. Now for as how this applies to our reef aquariums, I think that the increase in sulphate concentrations should not cause any problems. Low magnesium levels cause more, and the amount of Epsom Salt required to maintain the magnesium concentrations once they are up to the correct level is small. But having said that, it is better to strive for the conditions that our system inhabitants are adapted to and have evolved in. If a source of magnesium chloride that is not expensive and can be afforded can be found then go ahead and use it. Although because of the ease of access, price and simplicity of use, Epsom Salt is a great place to start, or even end with, maintaining magnesium concentrations. this is wat i found on web hope that help ppl with magnesium problem

ok at the same time pass u my bottle
