Please advice how long can I use my sand before I start to change it.

I have a few colonies of zoanthids that i bought last year, I've had them for about 8 months now and they have not really increased in number. This is kinda wierd cause the montis and sps are doing OK but the zoanthids have simply not increased in number. Also odd, my lps have never looked...

Hi all, new to TRT. Excellent site! I recently changed my 120 from FOWLR to a reef system. I had to cycle in 50lbs of new live rock. It has been about 3-4 weeks now and I have 2 questions: 1. Cloudy water-brownish color. I have noticed that when only my moon lghts are on, the water clears...

Zooxanthellae take in ammonia given off as waste by the polyp and return aminoacids...so more fish equal more ammonia, does this equal the more coral you can add to a tank? Zoo's convert co2 and h2o into o2 and carbs-polyps use o2 for respiration and gives co2 to the zoo's....so is extra co2...

It's a while before I have to worry about "old tank syndrome" myself, but the following article is interesting, informative, and pertinent to developing an overall strategy in a reef tank... http://www.advancedaquarist.com/2006/10/aafeature#h1 What do you guys reckon?

would it be that bad to fill the first time with tap water? i wanna fill it to do some checking, make sure every thing runs good. but i dont wanna fill it, then dump it out, then take forever waiting for it to fill with the ro/di. what would the harm be in filling with tap, after making...

OK, what is iron bleaching? can it be caused by iron in the water supply? this may be what i have been fighting for the last couple of months. i figured i was just adding some phosphates and nitrates to my water as my water filter has been waiting a replacement. G~

Today as I was cleaning my sandbed I noticed many little bugs (which i took to be copepods) and worms lving in the sandbed. Does this mean that I know have live sand because these critters are everywhere and if so should i disturb the sandbed if its only a very shallow one? I'd also like to know...

well, i have somewhat put a plan together of what i want to do next . i really like the idea behind the japanese tanks , with the corals growing on the bottom . my plans are to make a dome shape platform that will rest on top of the starboard. the high point on the dome will be 2" to 3" inches...

Can this be a problem in BB tank's. It seem's that when adding more fish to the system to get the coral's to darken it's the liquid addition of ammonia and urea that is important rather then the solid waste of the fish. A friend of mine recently switched his established reef to BB, now his...

Where did this come from?

I know the speaker from scientific coral seemed to believe the use of mud filters were beneficial to his operation. I have read that Caluerpa grows better in a mud base. Is this simply anecdotal, or have others experienced similar results? Thanks...

Hi All, I have a 40 gal. reef tank that all of a sudden is full of brown algae(?) on the glass. I literally have to clean the glass twice a day. The water is clear and ammonia, nitrite, alkalinity and Ph test fine. Does anybody have an idea what this is? I thought it might be my makeup water...

I'm still new to this. My tank is still pretty new. It was filled with water on Sep 26th and I'm still trying to learn as much as I can to take care of it. My wife, my daughter and I have all fallen in love with the tank and even though the tv sits about 2 feet to the right of the tank, it's...
