    100% Water Change

    So in my previous thread, I had an ammonia issue that was out of hand. As suggested, I did a 100% WC and now i’m wondering when I should start adding fish back. If anyone has suggestions, let me know!

    Chalice coral mucus damaging SPS

    When I do large water changes, I have a large chalice coral (echinopora) that gets exposed to the air so it ends up producing a lot of mucus. When I fill the tank back up. This mucus flows throughout the tank. Last time, it ended up getting on an Acro and monti frag and killed some of the...

    EMERGENCY Is my water safe?

    A follow up question to my fish having ich. I currently have lake Michigan water coming to my house. My friend told me it could be the reason my fish got ich. So I was wondering if it were possible to have a fish store test my water to confirm if it's safe or not? The reason I ask is because I...

    High Nitrates

    Hi guys, so I am brand new to this community and I figured I’d ask a few questions. I have been keeping aquariums on and off most of my life. I just recently started getting back into the hobby and I set up a new 40 gallon FOWLR tank about a month ago. I used Fritz Turbostart 900 to cycle the...

    Water Changes or AWCs... is one better than the other?

    A few months back I set up auto water changes on my Waterbox 130. It has worked amazingly well.. in theory. Back when I was doing bi-weekly 10-15% water changes, I would notice a happy shift in my tank after doing it. Corals and fish seemed to love the refresh, and things did well. With the AWC...

    Tap water->RODI water

    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 ?

    Higher alk waterchange?

    I am looking to change out about 10 gallons in my 90 gallon reef *88 gallons=tank+fuge* housing some expensive sps frags. If my current DKH is 8.2 and the DKH of Reef Crystals is 13 would that be too much of a change? I did the math and doing a waterchange would add about .5 DKH for 10 gallons...

    Too much water change a bad thing?

    Is there such a thing as too much regular water change? Apart from the cost consideration, is changing 20% weekly, split over 7-days, better or worse that than say 10% once a week?

    Do You Feed Your Corals Before or After Your Water Changes?

    Do you prefer to feed your corals before your water changes? Some seem to prefer to reduce what stays in the water column after feeding by doing a water change after, others seem to look at it as leaving fresh food available for their livestock after a water change, and some feed their tank so...

    Less fequent water change with skimmer?

    I got a skimmer for my reef a few months ago for some reason I thought I could get away with doing my 10% weekly water change to 10% every 2 weeks when I got the skimmer. After reading more online I’m seeing I still need to do 10% a week or 20% every two weeks. I plan on moving back to 10% a...

    Cascading Water Changes...Dumb Idea?

    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...
