    Phosphate and Nitrate out of balance. Help needed, stupid reefer here.

    Yeah the title sums it up. Phosphate was 0.7 so I used GFO and nopox to get it down to zero. Got dino, let the tank dirty out for months fed food, skimmer offline. Dino went away and now I have 25 nitrate and zero phosphate. Luckily I only have a couple of softies in the tank so nothing too...

    P04 Issues

    Alright, where to to begin. I have had a 80 gallon with a 30 gallon sump tank running for almost a year and a half after a restart. I got dry rock and dry sand, which is a mistake on my part, and I am on a fun roller coaster right now. Around 5 months into my restart things were going okay...

    Nitrate Levels in Aquaria vs Wild Reef Nutrition

    I often wonder how wild reefs are able to grow and thrive with such low levels of dissolved nutrients - namely nitrates and phosphates. I have an SPS/Acropora dominant tank and I maintain KNO3 solution on a dosing pump just to keep the corals alive - I try to maintain nitrates up to 5ppm...

    How necessary is it to clean your skimmer neck/cup.

    So - a recent thread reminded me of a question - how often do people clean their skimmer neck/cup. I do not do it regularly - and it tends to have a thick coating of 'gunk'. I always wondered if that was putting bad stuff 'back' into the tank - though I dont think it does. Answer the poll -...

    Good Nitrate to Phosphate ratio for a reef tank?

    Hello! Over the years this has been one of my favorite subjects. A while back I noticed my tanks doing a lot better with more NO3 than PO4. When the NO3 matched the PO4 on the lower side the tank begin to grow hair algae in the sump, and dark brown algae on the rocks, overflow box, sand-bed...

    How Many Test Kits Do You Have?

    I know...I have a problem. I was organizing my supply cabinet and realized I have clearly accumulated more test kits than should ever be necessary. BUT it has been helpful having everything I need at arms reach, and the ease of use of these kits has caused me to test consistently, which I’m...

    Phosphate testing

    I have a 180 gal mixed reef about a year old. I’ve been using GFO kind of blindly off and on for the last several months, I don’t use the GFO unless progress seems to slow down and it has always seemed to help my corals grow better again but I’ve read several horror stories about overuse of GFO...

    Phosphate solver?

    My phosphates are reading at about .25 and I am getting algae growth on my rocks. I am also going to assume that the algae is eating the phosphates which makes them seem lower than what they actually are. Before I started my reef tank my phosphates were extremely high like 10ppm+ so i dosed...

    Nitrates around 1

    My tank is reading Nitrates around 1 and Phosphates 0.04. The tank looks fine corals healthy and colourful, cheato is growing in refugium nicely, (hair algae in there too :( ) Should I take it as a false negative ie the cheato is using all the nitrates or would I need to increase it slightly...

    AL99 vs RowaPhos

    Hi Tim and everyone :) I am in the process of rebuilding my tank and switching to the full Triton method. I see that the recommendation is to switch between AL99 and RowaPhos on a regular basis in order for the Rowa to remove any aluminium that has leached from the AL99. My question is why...
