    Most (semi-reliable) Dipstick test out there?

    Hi, I currently have a large mixed reef system (around 300 gallons) which is currently being monitored by my apex trident (monitoring pH, salinity, ALK, CA, MG). I am just starting to get into SPS, and therefore want to start monitoring phosphate, nitrite, and nitrate levels more closely. The...

    With daily auto-water changes, i've not 'manually' remove water from my system for a couple of years. Have some dead areas in the bottom of my sump that have collected crap, going to stick a powerhead in there to keep things in motion going forward but about to get in a vac it out. Any reason I...

    Trouble raising nitrate level

    The nitrate level on my tank is below .1ppm. I have been dosing the equivalent of 1 ppm sodium nitrate for a few days and every morning I test its back around 0. I tested minutes after dosing and read around 1ppm and I even dosed to my water change bucket and got 1ppm. So I am pretty certain my...

    Should I Dose Phosphates

    Hello, I am a new reef keeper, I have a red sea 250 reefer (55g display) that has been running for about 3 months now. Everything seems to be going well, but about a week ago my nitrates reached about 10ppm (API Test Kit), and a lot of brown spots (possibly diatoms) and some green spots started...

    Tapering off Vibrant

    summary: I successfully eliminated bubble algea using vibrant. I slowly ramped up my dose from 2ml per week up to 5ml per week. It's taken three months but the bubble algae is finally gone. I think I'm going to slowly ramp down the dose over the next month or two. I have read that vibrant act...

    Low PO4 but High NO3 help?

    I've been battling some cyano and turf algae pretty much since I've been in the hobby 2 1/2 years ago now. About 18 months ago I thought I found the end all solution...that being the Zeovit system. Ever seen then I've been running the full system (Zeo Stones, Carbon, Zeobac, Zeostart, ZeoFood...

    Noobie reefer looking for advise with persistent algae & poor coral health

    About a year ago I made the mistake of buying a problem tank off Craigslist because it was a good deal (no extra charge for the algae). I’ve been fighting it on and off since. I’ve had bubble, hair, dino(I think) and most recently a red/purple one (red slime?) Also, my coral is clearly not...

    High nitrate after water change?

    So just 2 days ago i preformed a water change as my nitrate levels read at a high 25. I’d say I did about a 45% water change with r.o water. But when I checked again today my nitrate readings are exactly the same? The only thing I can think of is doing another water change, but i don’t want to...

    Maximum nitrate levels

    What is the maximum nitrate reading you know of where corals were kept successfully? What is the “breaking point” for the hardiest of corals? What corals are the most tolerant to high nitrates? Please input especially if you have large predatory fish! Thanks!
