Hello pros! Question.... I have a 125 with dual overflows in each corner. Each side has a 1 inch drain and a 3/4 inch return. My main pump is a Magdrive 24 (2400gph) with about a 4 ft head. Previously (like an idiot) I had a ball valve on my drain and no gate or ball valve on my return...

Up for sale!! 72 inch Giesmann 3x150w Metal Halide light fixture. I bought the light directly from Giesmann about 18 months ago and paid $2100 for it. i just replaced all 3 bulbs with Phoenix 14k. The low-loss digital starter ballasts work perfectly. There are NO scratches or dents at all...

Have a question for all of you smartie's out there.... Like the title reads, I am going to completely tear my 150 down and start over after 3 years of running. I am going to re-do my wood stand and replace the rock that I have with some beautiful Fiji rock that I was lucky enough to stumble...

I have a question that may seem out of the ordinary and I would like to hear your responses based on your theories or experiences.... It seems, for no good reason sometimes a fish will be, in what appears to be excellent health and in a matter of 24 hours, that very same fish....dies. Since I...

In this hobby, there seems to always be a way around the expensive LFS prices by buying a product for you reef tank that is not sold FOR a reef tank....with that said... Anyone know where to buy a good activated carbon granules cheap?

Making the leap with my 155 to a reef tank. Before I get started, I want to make sure my water is in the right place before I add my first coral. My calcium was low at about 320 as I was using IO salt with no added calcium or trace elements, to speak of. I have recently switched to Red Sea "Pro...

I have a fixture consisting of 3 MH lights, each 250w. I am trying to plug them in to the same surge protector and after starting up, they blow the surge protector after about 2 minutes. The room is has a 15 amp breaker and 750 watts of MH is less than 7 amps. I can run 2 lights all day....add...

I have found a 48" metal halide light fixture for my 135gal (6 ft). I know its made by Odyssea and I know their reputation is up in the air however, the guy only wants 100 bucks for it, brand new in the box. Here are the specs: 2x External Quick Connect 250W Electronic HQI Metal Halide Ballast...

So here is the issue.... I have a 135 Gallon with eight 39w t5 HO lights. (4 white, 4 actinic)...total of 312 watts. That is merely 2.31 watts per gallon. I have no corals as of yet but I would like to have them in the future. I realize with my lighting, I am very limited to what I can...

So I am going to add a clean up crew.... I have a small bio-load in my 155. Only 6 smaller fish as I only add one every two months or so. Just taking things slow, for now. I have a 40 gallon refugium with a protein skimmer rated for a 250 (expensive!!), and tons of chaeto. My water quality...

I recently purchased a few Chromis for my 155 gallon hoping they would school. The smaller of the 3 is a real hoot. He spends the day "on patrol" swimming the length of the tank, then back again, playing in the currents of the powerheads. He ate like a little piggy for the first few weeks I had...

OK, so my 155 gallon is about 5 months old now and the fish are doing wonderfully in their new home. I have 140lbs of lace rock and I perform water changes with RO/DI water every week (made at home with a $350 setup) , 30 gallons each week....like clockwork. My water looks good, all values are...

So my Pearlscale Butterfly is a busy busy fish. He swims all over and is about the most active fish in my 155 gallon tank. I have had him (it) for about 4 weeks now and I am noticing a small area on his left side that looks like it has been rubbed raw. Hes not bleeding and its not really a...

So, I introduced a pair of Clarkii Clowns along with a black/white damsel and a blue green Chromis all at the same time this morning in my 155g. They are the first inhabitants. At first, the 2 clowns seemed to follow each other around, through the rock, and seemed like pals. 6 hours later...

Ok, so my 150 gallon cycle is starting to kick in to high gear. I now have gone from 2.0ppm (stuck for 4 weeks) to .25 (in 3 days) and I suspect ammonia will fall to zero, sometime tomorrow. My nitrite is at 2.0ppm and nitrate is about 30. I assume the bacteria that turn nitrite in to...

Good day all...So, my 150 gallon tank has been cycling for almost 7 weeks now. For reasons unknown, my ammonia is still at about .75 (down from about 1.5), nitrite is at .50, and nitrate is at 50. It has been this way for about 3 weeks now. I slowly brought the water temp up to about 88F to...

So as I have written before, I have been cycling my tank for 6 weeks now (150 gallon, with less than 20 lbs live rock). I have watched as my ammonia levels have gone from a mere 1.0ppm (highest ever) to zero, which is great. My issue is, for the past 4 weeks, my NITRITES have been stuck at...

I have successfully set up a 150 gallon with wet/dry (synthetic filter w/bioballs). Only RO/DI water used. 120 lbs base rock and about 15 lbs of live rock. I was GIVEN two bottles of "smart start" by the owner of my LFS as sort of a "welcome to the hobby gift" (nice guy). I introduced this...
