Two days ago, I put in 115 lbs of Carib sea life rock into a 125 reef aquarium we are starting. After about 24 hours, the water became so bubbley that the skimmer was overflowing. Has anyone had a similar experience? I did not rinse the rock because it was treated with bacteria in the...

I am setting up a 125g, which is predrilled with 2 overflows. Each overflow has 2 holes drilled at the bottom of the tank. I have set up 2 drain lines, each running directly to the sump. My question is, would you recommend having 2 return lines? If so, should I run a separate pump for each...

I have a ceramic log that has a faint smell of rotten eggs every time I take it out of the tank to scrub it down. I do this every week with my regular water changes. I am assuming it is hydrogen sulfide, but why would it be associated with this one piece of tank decor? I have had no problems...

Looking to start up a 75g tank with an Oscar and electric blue Dempsey. Is an FX5 too much for a tank this size? I am looking for the extra gph, but do not want to overwhelm the fish, especially when young.

I am looking to keep an oscar in a 75g. I would like to keep at least three fish in the tank. What fish could defend themselves and look good in that size tank? Thanks in advance for your ideas.

I am looking at getting an Oscar, green terror and an electric blue jack Dempsey. My lfs said it would not be a problem for a 75 gallon, but it seems a little much. That would be about 30 inches of fish length. Let me know if my instincts are right on this.

Will the use of a glass cover over the tank diminish the effectiveness of reef led's in terms of the coral's needs? I am looking to keep a tank in a colder room and will need to keep a cover on it in the winter time to minimize heat loss.
