Dear all, Just to check with you all, I noticed that when I dipped my hand into my tank to do some cleaning, I have this fishy smell that stick to my hand after I take it out. Is this common for all of you ?

I bought a ocoral from a LFS yesterday but the lighting was not good in the tank and shop. I choose one of the brain and immediately it was packed before I can inspect it. When I put the coral in the tank with MH lights on, I got a shock when I saw that the slightly 1/4 of it not good. The flesh is not covering the coral skeleton. I am disapointed, can I call the shop and asked for an exchange. I don't think OP was out to cheat me but I guess it partly my fault b'cos I choose it. Anyone has similar experiences and how you dealt with the LFS.

I got some mature LR from a hobbist where it was covered with coraline alage - purprish colour. My tank has been cycling for a month already and I added some LS but after I did water change, I notice some of the LR where the coraline alage turn from purple to white. I know something is wrong where the decay process start but my tank has been cycling for a month and the nitrogen cycle has been through. I tested the water to verify and NO2 is 0, N03 is 20pppm. I though that the mature LR would add the process. What could be wrong. Was it the change of water ? I could not get much information about procedure to change water but this is what I did. Please advice if the steps are wrong. 1. Prepare a bucket of water and add in anti-chlorine 2. Add salt and stir till disolve 3. Check SG 4. Drain off water from main tank (equivalent to the the bucket of new water) 5. Add in new water into sump Could it also be that I do not have enough neutrient in my tank. ? Do I need to add in stogniguim (can't spell it but I was informed somewhere) to create more coraline aglae.
