water change help

would too many water changes be bad for a tank or would it be fine?

I've been calibrating my refractometer with RODI for the past 2 years. I now know that it's best to calibrate with calibration solution. I want to switch to calibrating with the solution with my next water change, but the problem that I ran into is when I calibrate using the solution my tanks...

Hi all,my tank reached the end of its cycle give or take a month/month 1/2 ago. I've since added 2 clowns, and a snowflake eel. I've gone though a 40% water change 3 days ago due to a alkalinity issue I wasn't aware of. Used RODI water to complete the change. Anyways, I'm leaving on a 5 day...

A few days ago I recently did a routine water change on my aquarium and when I plugged all of my equipment back in, everything seemed off. First, my Rainsford and Mandarin Dragonette were showing weird swimming patterns. The Rainsford normally liked to hang out in front of his hole but now he...

I’m running a smart dual sensor ATO. Do you all turn your ato off during a water change to prevent it from turning on? What do you do with your ATO during water changes? Thanks!

After a very large break, getting back into having a reef tank. In my previous experience, I had a smaller tank, and just used a simple siphon and two Home Depot buckets for water changes. For my new larger tank, I’m hoping there is a solution that doesn’t require me to drag 40g trash cans...

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!

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, I recently had a problem in my tank. It’s about 7 weeks old but it was going really well and I couldn’t really tell what had happened. All my corals were open but after i did a 20% water change they all closed up and none have opened back up since then. I thought it might be that one of...

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...
