I have nitrites in my tank. I did a water change 3 1/2 hours ago. When should I do another water change?

The other day I was in a rush to mix up some saltwater for a water change and I ended up dumping a bunch of salt into the water all at once which apparently (from what I have :read: about the subject on this forum and some others) caused the calcium in the water to precipitate and cover the...

Hello everyone, I accidentally ran my spectrapure refurbished 90 gpd RO/DI running overnight into the laundry tub for about 12 hours. Prior to that my handheld TDS meter read 0, now after running for about 10 minutes it's 2. Does that mean it's time to replace the filters? The unit is 8 months...

So I am switching from a 55 gallon to a 90 gallon tank. I am buying the 90 gallon tomorrow, no water or anything it. I need to transfer a yellow tang, picasso trigger, clownfish, porcupine puffer, chocolate star, and a snowflake. I don't have any corals or live rock in my 55. How should I do...

Hey TRT members, I haven't changed anything in my tank in about a year plus. I want to rearrange some rock I have to make better use of my space. It isn't stacked against the back of the glass at all. I have the three peak island idea where I could scrape all sides of the glass if i wanted...

So I am again moving to a new, bigger tank.. A couple of questions I am certainly unsure of and would like everyone's opinions. So first of all, sand from my old tank, put a little in my new tank to seed or leave it and start fresh. Also water, would you suggest putting any water from my old...

So my tank is 23 days old and I am starting to get the brown uglies on my sand and rocks. I tested my water yesterday and they are as follows: PH-8.2 Ammonia-0ppm Nitrite- .125-2ppm Nitrate-80ppm Calcium-360 Carbonate-161.1 Phos-.5ppm So I want to know is should I start my water changes and...

I've been searching around and I couldn't really find an answer. I hear everyone talking about doing 10-20% water changes a week. But what if you did it more then that? Would there be any consequence for doing it lets say, 30% twice or three times a week? Or is it just more work, more IO?

Been running a 90gal FOWLR for 6 months. Just bought 2 MP40s (awesome) and a BRS RO/DI unit so I don't have to BUY water anymore. I have to get rid of a couple of fish, Humma trigger, black trigger, and I think my Emporer Angle before I start putting corals in. Also, I'm upgrading my lighting to...

I performed a 10 percent water change on my 90 gallon tank 5 days ago and since then I have had a diatom bloom. My tank is a 90 gal with wet/dry, HOB reef Octo skimmer, dead rock that was starting to show what I think was coraline algae (it was purple), 3 inch live sand bed and 5 fish. I test...

I had a house call from LFS to come glue my rocks together , not only did he glue them together but completely reconfigured them so they are balanced and can be glued together. The design is good , BUT everyone is in different spots,.. My clownfish ( guess his name) had his anemone moved in a...

I have a 10 gallon nano reef, I have the AC70 filter on it, no skimmer and 1 nano powerhead. I top it off in the morning and before I go to sleep with distilled water and maintain exact water level (I also have a cut to size glass cover for the tank, excluding the 2 margin on the back for the...

I bought this gorgeous white pulsing xenia tree today and when I put it in my tank it became purple. Any idea why this happens? It was under huge metal halides in the shop and now it is under 3x20W CFs (10,000k, 6500k, and 460nm actinic). If I add a 420nm actinic to further "bluify" the...

Ok... So I'm moving in June, and am working on the planning stage for moving the tank. It's a standard 29g, with a 20g sump, beananimal overflow system. Currently I'm running with LR (probably about 30ish lbs) and LS (20lb). I am planning to use the move as a good time to change it up a bit...

I only do a water change once a month on my 38 gallon fowlr. I have 2 false perc clowns and 1 coral beauty. I have been doing this for about a year now aand my tank is healthier than when I did bi monthly or weekly water changes. Why is mine doing so good when people say you HAVE to change the...

I've got a 30 gal hospital tank treated with Cupramine and it only has 5 small clowns. Last night I did a water change of 10 gal and this morning the water was so cloudy I couldn't see through to the back of the tank. The cloudiness looks like when salt is first dissolved in a bucket, but the...

I have monitored my tank's change in temperature for a few days now. It appears that in the dead of night the temperature reaches a low of 79.1F. Before the metal halides turn off, the temperature reaches a high of 82.4F. This yields a change in temperature of 3.3F. Does this seem too large...

I was looking threw pictures and thought id share. the first picture is of the tank in sept. this was after about 2 1/2 months up and before i added in more live rock and other things. all that was in there was two damsels which are now living in a 10gallon cause i couldnt take them back i was...
