Any idea what this is and how to get rid of it? http://www.comp-connections.biz/tank/help1.jpg

I have 2 fiberglass cylinders one that holds 45 gal (Di H2O) and one that holds 25 gal (Ro H2O) I bleached these tanks out for days and rinsed them thoroughly, one week after storing H2O in them the Ro tanks H20 has such a musty smell and taste, we cannot drink it, the Di tanks water smells...

Hi, I'm going to setup a new small 20 gallon fish only tank and I already put some live rock in it. Is there anyway to speed up the cycling time for a new tank? so I can add fish sooner? Thank You!

my two juvenile clowns have suddenly taken a liking to my furry mushrooms, as a proxy anemone. they roll on their sides among the furry(?) bits and lay into the mushrooms at night. when feeding the mushrooms would occasionally close up like an anemone. has this tricked them into thinking that...

This weekend I drove out there to pick up some supplies and decided to finally 'upgrade' from my 175W 5500K venture MH bulbs to some 10000K bulbs. All they had in 10,000K was their house name "German" 10,000K. They could tell me anything about the bulbs except they were German made and would run...

Hi again all. I got my 90 set up with the southdown sand and it cleared after much diatom filtration. I just tested the calcium levels for the first time today using RedSea's kit. The problem is that I couldn't get a result. I followed the directions exactly but the sample would not change from...

Looking to get a 120 reef gallon tank. Its going to be in the wall. I was thinking of a 5 footer that was 24 inches high and 20 inches width. Or go with a standard 48x24x24 tank. What do you guys think ? Also what thickness of glass should the tank be built with ? And should the bottom plate...

Hi all. I am setting up a 90 reef and have added a bag and a half of Southdown sand but now my water looks more like skim milk. I rinsed it lightly before adding but that was no use. Any suggestions for getting the water to clear up quickly? Is the cloudiness just due to the calcium the sand...

So during last spring semester at college I lived in a frathouse with the majority of my fellow brothers. On of the brothers is a complete piece of trash. I mean real scum. This guy would skim hundreds of dollars out of our dues fund to furnish his room and pay for his share of the rent. He is also...

Hello, Anyone have info on Nudibranch / Spanish Dancer (Hexabranchus sanguineus)? Feeding habits in particular. Thanx Miguel

I have an eclipse system 6 that I am looking to turn into a nano with some shrooms and a few small pieces of rock and what ever else happens to grow. I wanted to put a live sand base, how many pound should I get for a tank that size? Also, what are the odds a false perc would survive in there, or a...

I am interested in getting rid of the chiller on my reef tank, it adds extra maintenance and complexity to something that should be a relatively simple affair (at least that is the idea right ;). So in this quest I am looking at lowering overall heat input in my tank. I have already removed almost...

Just wondering if anyone here has had experience with Hagen Phospahte Test kits, and if they have an answer to this problem. A friend and I each have a Hagen Phosphate PO4 test kit, his is included with the Briefcase test kit bundle they offer and mine is just the PO4 kit on its own, Both have...

Have you noticed how (healthy) Xenia coral stinks when taken out of water? Yesterday I was working on a frag for Mort and when doing the final separation from the mother colony I put my nose too close and I was reminded how stinky this coral was... I already noticed this odor weeks ago, but I...

I have a Knopf Calcium Reactor, and after 8 years I need to replace the CO2 pressure stage. I have 3 problems with the current CO2 equipment. 1. Three times in the last year it has dumped all the pressure in the 10 pound high pressure tank. I used to get a full year out of a charge, but the last...

Have a question about mysid shrimps living in the tank with DSB. I have read crabs/shrimps are not good for DSB as they hunt on DSB creatures... This warning usually applies to larger crabs like hermits and larger shrimps like cleaners... Do they apply to mysids as well? Would I benefit DSB adding...

Quick question. I seem to be dealing with an outbreak of cyanobacterium. (Which really makes me PO'ed given my weekly 15 percent water changes with RO water and light fish load. So the question, what is the major cause of this algae outbreak? Is it an excess of DOC? It doesn't make sense for it...

What I mean by Target Filter is a tank designed for removing one problem and not a general overall filter. I have on occasions problems with phosphates building up, so I was thinking of making a filter to 'Target' phosphates. The question is, what would I make and where in-line of the water flow...

Hi folks, Like the post before this one, this is also my first posting here. I've had a reasonable amount of luck with freshwater systems in the past and I'm looking to make the slow jump to a marine setup. Initially, only fish with the possibility of a reef tank in the future. I recently found...
