any thoughts?

Does anyone have any information about calcio crabs. I saw a large one at the LFS. I did a search on this site and did not find alot of info. Thanks for the help.

For all you people with DSB. When you move things around in your tank, do you get huge sand storms that last for hours, or is it just because my sand is so new. Sorry for all the questions, I am new to DSB's. I read all the info on the benefits of a DSB, but they don't discuss the small problems...

Any thoughts?

Alright lets start at the beginning. What are the levels in your tank? I need to know trates, phosphate. I also need to know the size of your tank and what livestock is in it? What are you using as a filter and what substrate? What type of water are you using, tap or R/O water?

There really are no corals that will thrive in that lighting. You might try some mushrooms real high up in the tank. But I think they will lose their colors and get real small. You would have a few more options if you did a upgrade to 110W VHO's. For exapmle I have 2 175W MH, 2 110W Actinic...

A few years back a friend of mine was trying to get a eel to eat a gold fish that I fed my lion for treats. Well I was not paying attention and the lion must have ate 5 gold fish before the eel ever got close. For the rest of the day the thing floated upside down in the corner of the tank...

I had the same thought, so I put the sand in a garbage can, filled with fresh salt water for 3 days, and tried to transfer bacteria over at that point as well. Does fine sand like this every really settle nicely? I think today that I will replace the filter pad in my sump. Maybe that will make...

I had a huge one a few months ago. It was about 6" and seemed very aggressive so I removed it. Small ones seem okay, but when they get that big you might want to think about removing them, especially if you are going to put coral in the tank at one point. My LFS sold a trap, it was about $4 and...

Well I went ahead this weekend and removed my CC and put in a DSB with all Home Depot sand. I also put in a 10 G slow flow refugium with about 5 pounds of LR rubble and some kinds of algea. I did not use any LS, I washed all of the CC through a strainer with old salt water to try to wash as much...

Thanks Up North Hermit, Thanks for the advice. Looks like you were successful and I'm going to try it. If anyone else has any advice I would like to hear it. Thanks Graham

My current 100G reef has be setup for about 1 year. The nitrates are starting to creep up and I'm changing over to a DSB this weekend. I am taking out the CC. I bought 250 lbs of southdown tropical sand and I am going to use only this. No LS. I currently have about 90 lbs of LR and many small...

Sun Polyps, (tubstrea Family) Great looking corals, moderate care needs. In the oceans they are mostly found in caves or shade areas. However in a tank I have heard that they can be kept in direct light or not. They do not have zooxanthellae, therefore NO PHOTOSYNTHESIS. They need to be feed...

A few times last summer when it started to get real hot, I would float plastic bags filled with ice in the sump. The water would circulate through the sump cool down and then circulate through the tank and slowly bring the temp down over about a 1-2 day period. This will work better than...

Not very much. Yellow headed, opistognathus aurifron, max size 4" good reef fish, needs deep sand bed for burrowing in. Eats most foods. Dusky, opistognathus whitehursti, max 3.9" same basic needs, have heard that they like to jump out of tanks, get top on. Look at a blue spotted jawfish; they...

Many people used to say that UGF were an absolute neccessity for a Salt Water tank. However for long term success, it is important not to run a UGF. For one thing an UGF does only biological filtration, and it does not even perform this function very well. Bacteria was once thought to only grow...

GOOD LUCK!

Place them on rock work, not on the sand. Bacteria can attack them on the bottom. They attach to the rock work, and do not like to be moved, so pick a spot that you like, and works well. Graham

A 150 should be large enough for a while, and might be good enough depending on how large the shark gets. They grow to a max of 40 inches, but not likely in a home aquarium. They are reef sharks and really not all that active. They have powerful gills and do not need to swim to breath, therefore...

A small PC unit works well for lighting over the sump. Will grow coraline and some other good plants like caulerpa(sp). You can get a small PC unit that fits over your sump for about $100
