water

I just got my results back. I took my sample the same week that I started a chaeto reactor so know my nitrates and phosphates will come down, but am concerned that my nitrates are 135x my phosphates instead of about 10x like I see being ideal. I’m thinking of starting to dose NoPox but am unsure...

I have a 55gal long tank, all types of coral. Right now mainly softies(Zoas) and trying some sps(birds nest) and Lps (blueberry leptastrea). It seems my Stony corals are having some issues and are not to happy. I don't think i ever thought about how powerful my wavemaker we're until I saw...

Hello, So I have a 25g JBJ Biocube. It was doing pretty good until recently. Been having issues with Phosphates and Alkalinity. So I’ve been going to the LFS weekly and having them test everything. Asking what I should do or not do. I went in yesterday expecting my Alk to have dropped and it...

How do I get my water to be that amazing clarity that I see in so many aquariums? My water parameters are on point but at times my water can look murky compared to some of the crystal clear pictures I see from other on this site..

Why would my fallowing tank of about 1 - 1.5 weeks be cloudy? Should this be of concern? I have a microscope if you'd like me to take a sample. Tank is 4 months old, fallowing for diseases for 1.5 weeks so far.

Ok, so I have a nano reef, its 50L having some algae issues at the moment. But my nitrates and phosphates of course go up over time. How often and how big of a water change should be performed on such a system. It does not use a protein skimmer and is LPS only. After noticing my nitrates and...

My reef has (very nearly) made it to the first year mark - a personal milestone - and despite a few "exciting" moments, we're doing ok and hanging in there... I store 100 litres (Metric, sorry - I'm in Australia) of RODI water in a rainwater barrel that I bought from the gardening section of a...

I am new to the forum, and I need some advice. I have a Fluval EVO 13.5, and it is FOWLR. It is cycled for about two weeks now, and I was thinking of starting a reef in October or early November. Now here are some questions I have before I convert the EVO to a reef: • I live in a rented...

Hello everyone, since I upgraded to a bigger tank. My water changes uses a lot more water, and means more trips to the LFS for RO water. Was looking into getting a RODI unit but can’t decide which one. As usual, I don’t want to break the bank lol. I am also going to post my city’s water tests...

Hey guys, I need help ASAP. I purchased a used 90 gal aquarium to upgrade my 37 gal all in one reef tank. Over the weekend I transferred over to the new tank. I used about half of the original water and half of my water. The previous owner’s set up was FOWLR. I have a mixed reef. Well come find...

Hello, who sell reverse osmosis of aquatic life, 100 gpd?

I'm just curious about sea salt. I'd like to know more in depth of why it's not good to use sea salt that has moisture in it to use it in a fish tank. I'm a little confused because it gets wet/ dissolved into our aquariums and I'm pretty sure alot of salt on the market comes right out of a wet...

Hi all. I set up a new tank last month and this is the first time I got my water from my LFS to do a water change tomorrow(4gallon water change, approx 25% of tank volume ). However I see that there is a brown deposit in the container(pic attached). Please let me know if I need to worry about...

I just did a water change and shook out my chaeto, and the water looked like this. Does anyone have any ideas as to why it is brown and what is causing this?

Hello! I am a saltwater newbie: been running a fully cycled Fluval Evo for 2 months now. All equipment are stock. The ph has not been super consist, but for the last two weeks it has been a steady 8.3. Ammonia, nitrite, and nitrate have been consistently at 0. Salinity has been steady at...

I have A 75 gpd RODI system, the water coming out of it is a consistent 0 tds, but my tds meter says the water coming in is only 2 tds. I was wondering if the number is accurate, and if it was if I don't need to use the RODI system at all and just condition the water?

Hi guys, Back in the hobby after a seriously long hiatus - so practically a noob now. Have a question on using NSW for my pico. (It's a 5g Fluval evo that I perform a 90% water change on weekly) The natural sea water I collect here in Nassau has a salanity of about 1.028 - 1.029 when I...

Today I came across a YouTube video... I know,I know, don’t trust YouTube vids. And that is why I’m here asking. The video claimed you really only need to test Temp, Salinity, and PH. What are your opinions on the top, or most important parameters to test?

I have had my Red Sea 425 xl set up almost a year. I took coral out of my other tank right before a Dino bloom. I cleared those up but no matter what I do I still have what looks to be detritus. Tds is zero from RODI water. No overfeeding and no matter how often or how much water I change, it’s...

So I bought two of these new HDPE water 5 gallon containers last week and I wanted to use them, but they have kind of a funny chemical plastic smell even though they are supposed to be used for drinking water. Other than rising them out should I do something else...

My salinity is rising slowly rising and I don’t have an RODI system. I do have an RO system that I drink from but I was told that RODI is better for the fish. Any ideas what water I could use to top off my tank? (my RO has a TDS of <30).

Looking for some advice here... Last week I sent in an ATI ICP test for both my tank water as well as my RODI. The results unexpectedly came back with 36ppb copper in the RODI water (as well as 4ppb tin). Where could this copper have come from? I don't have copper plumbing in my home, and...
