water change

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...

Hi I'm new to the saltwater hobby and was wondering how would a water change be done on bigger aquariums (100 gallon +) Can I get a step by step guide? thanks!

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...

Hello all, I'm currently in the process of buying a house. This house has a concrete floored room that will be my first ever fish room. I would like to set up a nice mixing station like a see so many of you have. Does anyone know of a good write up on how these mixing stations are plumbed, how...

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...

hi y’all… we were in our LFS today and overheard the owner telling his main guy that he found the ‘sea slug dead’ in one of their tanks and they need to immediately do a water change & that the water was cloudy in that tank due to the slug dying.. we have one in our sump and i’m curious, if it...

Hi all just a quick one currently coming to end of week 1, no sign of cycling yet (two clownfish) - planning on doing a water change at 2 weeks, should I still do this change if there is no sign of cycle beginning? Or should I wait until ammonia and nitrites have both risen and fallen before...

I have 0 nitrates, I’m running a fuge with cheato for 5hrs a day and now I’m wondering if I should turn off my Protein Skimmer??? The 75g tank has been running for 2-1/2 months with live rock- 4 clown fish, 1 yellow tank and a few clean up crew, and have a good amount of soft coral. Anythjng I...

Hello, This is my first time posting here, so thanks in advance for the advice. I've been in the saltwater hobby for eight years and I'm moving out to college in a few months. I have a 2.5 gallon glass aquarium (w/ HoB filter & clip-on LED light), and I was thinking about setting up a pico...

Hello, This is my first time posting a question, so thanks ahead of time for your responses! I'm looking forward to learning here... I've been in the saltwater hobby for 8 years and I'll be moving out to college in a few months. I was looking to set up a pico reef using a 2.5 gallon glass...

Hello R2R! So I am getting ready to set up a "smart" water mixing station. With that, I am in the beginning stages of planning the design. I have my hands on 3 65-gal pickling containers, so those will be my storage containers. 2 drums will be stacked on each other (connected with PVC) for...

Hey everyone, I just recently got an apex and am looking to set up some auto water changes with the dos system and have a couple questions: -If I have a 20g tank, is it hurtful to do a 1 gallon a day water change? I currently do a manual water change about once a week with 4 gallons or so...

HI everyone, So I've been doing a weekly water change of 20% which is ~4gallons weekly. However, many people in the hobby have told me that that is too much and probably do 20% every 2 weeks. I like my weekly maintenance but should I make that 10% instead? I have like 15+ LPS corals, 3 fish...

Hello, So I’m setting up a new 75 gallon tank with sump and I need a lot of water Fill it in. There’s a Water Mart a Water filter Store that sales filter RO water that is abt 2-4 TDS. Is that ok to use for a mix reef set up? Is it bad or good??

Does anyone use an inexpensive utility sump pump to move saltwater from their Brute (or mixing station) up to their tank? I need a pump with at least 15 of head height, as I'm pushing water up the stairs from the basement. Most of these utility pumps do not indicate if they are safe pushing...

Hi all, new here. I’d love some guidance/advice from aquarists who might be able to help me figure out how to bring nitrates down in my tank. My tank is little over a year old. 90 gallon with a 30 gallon refugium, protein skimmer, with some Chateo growing beneath... The tank previously housed a...

Hey guys, I have an 150 G aquarium that's been running for roughtly 2 months. In it I have 2 clowns 1 sainfin tang and 1 lawnmowner blenny. I've been wondering how often I should do my water changes since the aquarium is so lightly stocked. I'm currently doing 7-10% every other week, what...

I have a 75 gallon tank. In 2 weeks I need to do a 75% water change after treating flukes with prazipro in my display tank. How do I do this, I don't have the space or bins to mix that much water ahead of time. So what do I need to do, to do this large of a water change safely for the fish. Do...
