water change

I bought this used 3-4 years ago and never got back to setting up a larger tank. Wanted to do automatic saltwater exchanges to get away from dosing. The litermeter still has the protective covering on the face.

So I just finished my first water change, but I'm about 1.5-2 gallons short of new fresh saltwater. My current salt is reading 1.027 with a refractometer. Can I just add 1.5-2 gallon of RO/DI fresh water to make up the difference or should I mix 2 gallons which is what I'm in the middle of now...

So in a continued effort to understand what's in my City Water and what poses a potential risk and would need to be filtered and treated for a tank (Fish Only With Inverts), I found my local plant water quality report, and am curious from others who have more knowledge than me, how good (or bad)...

So I currently have a IM 50 gallon AIO. A 10 gallon, 20% water change is quick and easy on a tank this size. However, I’ve already run out of room and am planning an upgrade. As I was considering a size, one question stuck with me: Should I pick a tank size based on the size of water change I...

Hi, I use RO water, perform bi-weekly water change. I notice green algae on the rocks right after my water changes. The RO filters are 3 months old and not fully used to their capacity. What I did notice was, if I don't change the water for 4 weeks the water was relatively better than 2 week...

So being from Australia, I know the need not to waste water, and I had a random idea that came to me last night and wanted to see if people do it or can be done. I have a 500-litre system, and when I do a water change, I normally have the hose down the drain and off to where ever it goes, but...

I’m sorry if this is a “common sense” question, but I want to make sure that I understand everything correctly before I start up my tank. I’ve noticed that when people talk about doing a quarter or third of a tank water changes they do it from and to the sump. Is it correct to assume that you...

Hello, R2R! I'm in the process of standing up a new Reefer 250 v3 system this summer and as its in an office, I don't plan on doing regular water changes with all the investments I've made. I have an Apex EL system and multiple DOS, Trident, ATKv2, FMM with various modules and sensors, 1Link...

Hello! trying to help the tank recover from a skimmer that broke and wasn’t working for 2 or 3 weeks. Everything looked great so I didn’t test ( I’m kicking myself ) while I figured out how to get it running again. Frogspawn started looking a little depressed this week & I just got the skimmer...

Hey all Thought it would be a good idea to share what I've done to create my auto water change system! I've used the Arlic grid connect for all the control and have level switches to limit the volumes of water being moved. I've currently got it set to run once a day at 5pm and changes out...

Another question that has been beat to death over the years, I know….but I haven’t really heard of it keeping up with the times. In previous tanks (pre Rollermat) I was religious about my water change percentages (I started with 10% weekly manually and graduated to 1% a day when I setup my first...

What Do You Guys use to keep your water Crystal Clear?

Hey guys! It's me :D If you have to attend to other fish hobbyists that are having emergencies or something, go ahead xD But what I want to talk about is how much do I change water. I have a kind of small tank, and I want my fish to have the best way of life possible, so I started feeding them a...

Is there any reason to do water changes other than nutrient control? My tank has been doing really well with no water changes and staying consistent. phosphate at .05 ppm and nitrate at 20 ppm. I’m dosing all for reef that covers major and trace elements. It feels weird not doing a water change...

Hello everyone, I've been having issues with ammonium readings in fresh made ro/di water lately. I'm using this ro setup from BRS and swapped all the canisters last week, however the problem still persisted. So I upgraded the carbon block to this and took another reading again no change. Here is...

Anyone ever test their salt water diluted in their garden? I know of many plants that are in constant need of the same nutrients that is in the water we have left over from the changes.

I'm trying to figure out the settings to perform a 25 gallon water change profile that I will add to my AWC DOS pump head configuration. This is my current DOS_ADD configuration Fallback OFF tdata 08:00:00,1,18,3,133,2,88,84,3,157,0,0,10,0 If KILL CLOSED Then OFF If H2O CLOSED Then OFF If...

So finals are looming for me so Ive been swamped with college work the past couple days and haven’t been topping my water off (I know I know ATO). I’ve been testing my water daily this week trying to determine my nutrient intake. With today being day 7 I finally started to see a drop in...

My seahorse is suffering from snout rot and I've been using Kanaplex to heal her. It says up to 3 doses and I hit that 3rd dose yesterday. Can I repeat a 4th, and possibly a 5th dose if need be? Do I need to change the water out if I can do the 4th dose?

hey sorry about the heading... i saw this on youtube he was using a 'jiggler' to start the siphon, which seemed to be a great idea, but it's made of metal. after some research, it's used for fuel tanks etc and made up of lead or some form of metal question: would it be safe to use in the...

I am not sure if this is a stupid question or not but ive have noticed my tank has crazy phosphate spikes after every change. maybe stirring the sand up too much or something? The new water always tests 0 phosphate (i am using hanna) but after the water change it can go up to 0.8-1 which...

let me try to explain. i'm sure it's been covered in the past by someone, but wasn't able to find the exact term used when doing a preliminary search so, i've been looking at making water changes less laborious. would it be advisable to take water out, and then just put water back in, OR adding...

I got motor oil in the tank.... I’m gonna try and keep this as short as possible and provide as much info as could be needed to help find a potential solution. I have a 1 year old 30gal half moon, mixed reef with a HOB filter. Roughly 30lbs or more of live rock, and 20lbs of sand maybe more...

Hello fellow saltines, This might be a stupid question (or at least a newbie question) but how do people do water changes on their pod culture tanks? I know a lot of people keep pods in their sumps/fuges so maybe this problem isn't applicable but for people maintaining separate culture tanks...

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...
