water

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).

Hey guys, i'm going to tell you guys about my 1 week old reef tank and some of the concerns that i'm having that I don't know how to solve. The tank is a 40 gallon breeder with a population of just 2 Onyx (Sea Quest Line) Clownfish. It's filtration is an aquatop Forza canister filter (which...

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...

It occurs once or twice a year (actually more). I neglect to replace my RO/DI cartridges when needed. Maybe because I left it running for several days while on a trip. Or maybe because the last carbon block I bought was delivered 2 weeks later than expected. Or maybe because I had to do 2 * 70%...

I started a 15 gallon reef tank about 3 weeks ago and used tap water with a water conditoner, everything has been doing good other then having alge issues and i am aware I should be using RODI water. If i start doing water changes with RODI from now on will that tap water be filtered out ?

I'm new to the hobby and I'm thinking about getting an RO system for my tank, I've been using tap water with a conditioner(i know its a lot less than ideal) hence the reason I'm looking to buy an RO or RODI system. the quesion is, is an RO system good enough or better than tap with a...

I’m running two carbon, one paper, one membrane, and one DI canister. I just replaced everything as I’ve recently moved and I’m on well water. I bought a higher quality membrane and it’s typically 5 ppm before hitting the DI. Based on what I read it sounds like that’s on the money. Problem Is...

I’ve had a few rock flower anemones for a while and they’ve been doing great in my tank. I recently got a new one from a company that’s been giving me trouble last week and it appears to not be doing so good. What are signs that a rock flower anemone is dead? Also what steps should I take if it...

I’ve recently moved to Colorado from Florida. I’ve noticed that the tap water here is cold enough someone LITERALLY does not need ice lol. In fact when the rodi was running at night to fill 100 g system (Total water volume). There was condensation on the unit. At just a hair under 80 psi and...
