Hey everyone, I've been having issues with my sps corals for the past 6 months or so, and just wondering if nitrates are the issue.... I finally figured out how to do a high range test of my tank and the nitrates come in at 16ppm. I know this is high, but several of my sps corals have...

My nitrates are off the charts high. I learned this about 1 month ago. No algae whatsoever. I was over feeding and have since cut way back on that, have brought my sandbed down to 1". I have a refugium and put more macro algae and mangroves in it, have been doing multiple water changes and just...

I have a 65 gallon tank. there are a few corals, live rock and 6 fish. Right now I have a HOB filter, a POS skimmer. I tested my water last night and my nitrates were extremely high. I'm planning on doing a 25% water change tonight. I'm thinking my filtration is to blame. I have about $150.00 to...

I moved a 55 gallon tank (2 weeks ago) with live rock, sand and 5 fish. Whem setting it back up I put the live rock back in over the old sand and put the fish in. after testing the water my nitrates are over 160, phosphates are at 2 and everything else is good. I did a 50% water change with RODI...

Hi all, I am totally new to fish keeping and have been left to take care of a tank, I have been completely thrown in at the deep end and need help. :doh: Let me start by explaining that my husband has left (it was his tank) and now im having to learn all about keeping a saltwater aquarium, and...

Okay here is another thread about high nitrates, but after thinking I had this beat just got an awful reading tonight. The tank is 125 gallons, i think around 20 gal sump, reef octopus 160 skimmer rated to 160 gallons, at least 150 pounds of live rock, about two inch bed of sand, hydor mag 6...

I simply cannot get my nitrates level down in my 29 gallon biocube. All other levels are right where they need to be. I replaced half of my bio balls in the back area, added some ceramic balls, frequent water changes. I have gone to feeding every other day and I'm simply not having any downward...

I have been having issues with my nitrates for about a month now... My skimmer quit working and they have crept up to somewhere between 80 and 160ppm. I have since replaced the skimmer with a Reef Octopus 8 but it has only been up and running for less than a week. The tank is a 125g w/ 29g...

We have a 55g FOWLR tank. its been up and running about 2 months. we are using a Fluval 406 and 2 hydor powerhears we recently had a big nitrate spike that killed 2 clown fish and a couple damsels. We did a small water change but I tested the water again today and now my pH is crazy high too! I...

Tuesday we added, against my better judgement, a dog face puffer to our 55 gallon tank. (Dear husband's idea) The guy at the LFS convinced us that he would be perfectly fine in our tank with our protein skimmer.So last night we noticed the tank getting cloudy and saw little white...

Ok, i have a 75 gallon saltwater tanks that I have had up and running successfully for years, however, I recently bought a corallife 29 gallon biocube and here is what happened. the guy where i bought it from told me to use water from my established tank, i bought live sand and bought a big...

I have a 20 gallon reef tank and all is well. All my readings are perfect except one, my nitrates have been about 80 the past month. I had just purchased a Coralife Protein skimmer 65G the newest model will this help, is this a good model I hear pros and cons and do not know if I made a correct...

I have had my tank up for 11 months. It seems like I am doing everything right but I cannot get my nitrates below 40 ppm. I have a 125 gallon tank with with a yellow tang, a powder blue tang, two clownfish, a coral beauty, and an emperor angel. Several sps, an lps and a carpet anemone. My...

I'm lost, confused but not ready to throw in the towel. :crap:I set up my 50 gallon reef tank 8months ago with live sand and about 55lbs live rock. I added not long after I set it up (like three days later) 3 blue damsils, 1 clown, 1 hippo tang, 1 bio color benny, dwarf coral angel, coral banded...

My 120 gallon tank just recently finished cycling saturday morning. I performed a 20 gallon water change and my nitrates are still around 40-60 ppm. Would i be ok to add 2 small fish like a dottyback and a royal gramma? Or should i wait until my nitrates lower?

Hello everyone, First off i wanted to tell everyone hello on the boards, I have been doing some research and stumbled across this website with almost everything i have searched. I have recently come into possession of some hand me down saltwater tank stuff, including sumps, tanks, filters...

I have a "friend" who has a 75 gal reef tank that is experiencing high nitrates in the 10-20ppm range. What would be the best coarse of action as far as water changes go? Should "he" do a larger one to get those pesky NO3's down or do a series of smaller water changes?
