water change

dual head 100gpd Steiner pump. Works great, used for about a year. I used it for automatic water changes and it worked perfectly. Let me know if you have any questions. Thanks 300 tyd

So, I recently set up a 10 gallon tank next to my 20 gallon mixed reef. Originally the 10 gallon was a QT tank, but it has now served its purpose (I never needed to medicate) and I don't plan on adding any more fish to my 20 gallon. So I'm thinking of converting the small tank into a little...

Hello, reefers! Around Thanksgiving this year, I will be leaving the country for a month, and my biggest fear is imagining what my reef is going to go through. So, I look to the thousands of reefers here for advice on what I can do to prevent the most common mistakes. Since I have been...

I am looking to build a ULM tank at some point that is fully automated and I have come across RODI units being plumbed directly to a sump or ATO within the cabinet to eliminate the need for carrying buckets of water. Redundancy of failsafes to ensure flooding the tank as well as your home does...

Apex Auto Top Off Kit --- ATK. --- $175 Shipped Purchased new a few week's ago, and I am getting another ATK on another route. Great Deal, In Original Box:

I have a standard 75 gallon tank. I was wondering if I need to take into consideration the volume displacement of my live rock and sand when calculating the percent of water to change. For example 20% of 75 is 15 but with 85lbs of live rock my actuall water volume is only 62 gallons and 20% of...

:( Not sure why or how my fish are starting to disappear one by one. So far have 3 fish have "disappeared" all of this started after i did 25-30% water changes for the past 2-3 weeks. I'm positive it's not the salt, my WC procedure is simply adding the RODI, adding salt for 1.026 salinity and...

Going to do 20-30% changes over the course of the next two weeks, I was thinking of adding a full bottle of bio spira at the end of the all the water changes to keeps things balanced. Good idea or bad idea?

If you don't mind sharing some pictures of your set up? Thinking of setting up a drip system for water changes to help myself get lazier :p

I have several more buckets in the house as well. Needless to say I found a way to really put promotions to work and got an incredible deal on salt. In the future I plan on sharing these deals when I find them so subscribe to my build thread below. I chose buckets over boxes because I assumed...

So I am new and I am sure this question has been asked many times. Today I tested my water and everything looks good. Ammonia and Nitrite are at 0, Ph 8.2 and Alkalinity is at 10 dKh. My salinity is at 1.024. The problem is the nitrates. I measured a 20 ppm so I changed 30 gallons of water...

i have a 55 gallon mixed tank that had been up and running for about 6 months or so w/o significant issue. I have been battling high nitrates, but everything (fish and coral) has seemed happy. In a foolish attempt to lower my nitrates I did about a 50% water change and it killed 5 snails, a...

Hey all, I was curious if anyone did continuous water changes i.e. remove and add water at same time and if so what kind of pump they were using? Thanks

Water Changes and Evaporation I see all these people posting about how much water changes they do, some will change as much as 25%/week or more! But most often than not it is a lower percentage than that on a regular monthly basis. I just see this as a major hassle, nutrients being flushed...

hello all my tank as been up and running for about a month. I have BRS dry rock with live sand and about 15 snails for my clean up crew. I’m running a skimz protein skimmer , BRS carbon reactor and a chaeto reactor. I do have a small micro bubble issue as I have a small sump. My question is it...

Hey everyone, per usual I am here with another noob question. I made saltwater today for a water change but I won't be able to do the water change since it's late. Is it okay to leave it in the Brute Trashcan? I never had stored water, I always immediately used it so first time storing it till...

Hey everyone, I have a 125gal DT and probably a 10-15 gal sump. I plan on doing a 10 gal water change from the DT but I have a feeling that its too little. It is currently a FOWLR system with 2 snails, 3 shrimps, and 12 fish. Would it be bad if I did 10 gal changes every 2-3 days to get...

I have been getting asked a lot of question form new reefers on what all is involved in maintaining a saltwater reef tank. Yesterday i decided to film my "weekly" routine of maintenance to give a good overview of what all is involved in maintaining a reef tank. Below are my general weekly...

I once had a water changer that had a small water line that sprayed water along with pulling water out a larger hose at the same time. Had a cartridge dechlorinator attached to the water hose. Worked great on my 150 cichlid tank. It gradually changed the water. Depending on ground water temp...

I normally drain my sump when doing water changes but up until last week it had no live rock in it. Will the live rock start to die off during water change?

like the title says, looking for a Litermeter. If you have one, or one with accessories, please let me know as I am wanting on asap. Thank you!

5 Ways to Protect Your Tank from Contamination A tank in your living room may be surrounded by hazards

I use one of my Neptune Dos's for automatic water changes. The salt line got totally clogged recently. Have you guys experienced this and how do you keep your lines clear? The tubing goes into my salt mixing trash can which also has a power head in there. Both the power head and the bottom of...

Hello again everyone. My tanks just got its first few corals in it and I had a question. When I do water changes in my 29g the top of the rock work is exposed to the air. Since I obviously don't want this to be blank rock forever I was wondering, how long can a coral survive outside the water...

I am fairly certain this is a dumb question but here it goes. I did a water change yesterday evening, about 4 gallons. My water has still not cleared up. I'm going on vacation Saturday so I'd like everything to be ok before I leave. Temp and SG matched. Biocube 29. Thank you!!
