Has anyone used crushed marble as a substrate. The size is about .25 mm average. Home depot has it here in SoCal for $4.49 a 50 pound bag.

Hi there I have updated my site - http://www.saftkongen.dk/Reef%20Page/MAIN.htm - Its in danish, but click on pics - they dont speak any langue :-D Happy reefin

Anyone know of any good sights to ID corals?

A number of years ago I had a 100 gallon reef tank. I had a pretty typical setup, wet-dry filter, large home made skimmer, some kind of auxillary power-filter & secondary skimmer combo thing hanging on the back, about 5 or 6 floresent tubes. This was my first venture into reef aquaria. My...

while building a wall the other day holding a clay house brick a thought came to me? this clay brick is porous like LR would it be good enough to support the right kind of bacterial for denitrifying. this is an off the wall idear so dont flame me for it !!!!!!!!! Regards David

Have you tried their MEGA MARINE yet? I have purchased it because HIKARI was always working for me if we speak about fish food, but I am dissapointed with this particular purchase. First - they look very "processed", I have a feeling I am feeding with dried pellets soaked in water. And when I thaw...

has anyone checked their before & after line pressure while installing a permeate pump. i'm curious how well they work. thanks shane

I broke the center tube in my ETSS 500 skimmer while cleaning the unit this evening. It fell onto the floor and snaped in two. I can order a new one from the manufacturer but it probably won't arrive until Tuesday of next week at the earliest. To make matters worse I am going out of town for the...

I seem to have a problem with the screws that tighten the skimmer box to the mag...there to short, I even had Jason at Aqua C send me some a little longer and they still don't tighten against the mag like they should? Anyone else have this annoying problem? Its become troublesome to make sure some...

I think the two lower anemones are Aiptasia pulchella or mutablis and Aptiasia Palida. The ones that looks like a bubble tip I can't identify. The white tube is probably an encrusting sponge. I have quite a few white sponges and some encrusting sponge. Don Geddis wrote: For those who enjoy...

the one's I have had in the past have all been quite loud IME I can hear them at the other end of the house which is about 65' from the tanks. its not a distractive sound thought and is not a "bang" sound but more like a "click" sounds a lot like the glass of the tank cracking. kc "logan"...

Recently I placed two, consecutive orders for 200 gallon IO salt mix buckets. One from BigAlsonline.com, the second from PetSmart.com Both buckets had a regular UPS shipping label stamped in red ink with "REVENUE AUDITED" text and a bunch of numbers. There was a reference to New York city or state...

FAIW ive never liked TEC bassed chillers for reducing the temperature, I do however like how they hold temperature. I also had one on my 7g nano I just recently tore down the tank, but it was never a problem. -- -- richard reynolds

Can anyone recommend a good book on reef keeping that is fairly detailed with examples of setup? I have the Reef Aqaurium book by Sprung and Delbeek, however it does not go to in depth about the actual setup of a reef aquarium. They talk about numerous methods but no real hard data of what would...

Has anyone had trouble with exposure to an excess amount of iodine with their tank and had thyroid problems because of it? Has it been documented anywhere? I regularly dose my tank with iodine for my xenias and put my hand in the tank frequently. I have recently found out that my Thyroid is...

hi. Sounds like they have some really cheap temperature controller. They need to mention the 4 degree delta in the spec on the web... Anyway, I wonder if the problem described below has to do with close proximity of the output and input to the chiller. So where in the tank is the chiller input...

I was wondering from all you reefers out there that run MH lights. Is there a big difference in the power used by the different types of ballast? Bulb life, heat given off by the bulb... I know there are 3 main types, Magnetic, Magnetic Pulse start, and electronic. What would you say to buy if...

I think most around here consider the Seaclone kind of crappy, but some have used it and felt it was just fine.. I *think* I read something about they had kind of "re-vamped" it somehow and it might be better now. On a larger tank though you might need something better. And another bit of advice...

Has anyone here used this type of canister filter on a reef tank - Ocean Clear Canister Filter. Any info appreciated. I wouldn't use one on a reef tank, but I've used them on several other systems and recommend them highly on the systems I spec out. Very good filter, forget the one with the...
