So my first setback today. I noticed one of my clownfish was missing and after hours of searching I found him in the back of my rear sump of my rsm c-250.im hoping he's just jumped into the sump and then died but I'm worried something could have caused him to commit suicide e.g. Stress. I do...

My 250l tank is about 7 weeks old now and I've recently experienced the deadline cyano outbreak. In terms of stocking I have gradually added 4 fish, a few corals and a small clean up crew consisting of snails, crabs and a brittle star. One of the first purchases with my tank was two jebao wp25...

Ok so treated myself to a new soft coral which I believe is a devils hand? Anyway I've placed it quite high up in the tank and it was fine for 2 days although now it appears to have dropped. As a newbie can anyone offer me any advice?

Ok so I'm on day 10 of the reef mature program on my rsm c-250 and I have just added my first clean up crew to the tank. I checked my tank parameters this morning and the the readings were nitrites and ammonia both showing as zero although the nitrates were up at 20. I spoke to my LFS and they...

Hey just setting up my new rsm 250 and thinking of getting the jebao twin controller with 2 wp25 powerhead. Would.this be too powerful on a 250l tank. Also what is everyone's opinion of these pumps they seem to be a good cheaper alternative then the vortech pumps.

Hey everyone, just on day 7 of cycling my new rsm 250 and getting close to adding my clean up crew. I'm a complete novice when it comes to keeping a marine tank although I have kept tropical for a number of years. I must say so far I'm impressed with the rsm c-250 although I do have a few...
