Hi all I am new to the hobby. I started my fishless cycle on the 1st of December. I added dry reef, coral sand, decor (I believe resin; LFS said it is safe for saltwater tanks), a heater, a wave maker, and a filter with an active carbon filter. I filled the tank with RODI saltwater I bought...

Hi All, I`ve been in the hobby a while now. I have had good success with Softies and LPS but when it comes to SPS I just dont seem to be able to hit the sweet spot. Tank is a DD Reef-Pro 900 (290 Litres total system), I have a Radion XR15 (Blue) at 100% on the AB+ Setting, 10% water change every...

I have 4 Hanna Checkers for sale. I have had them for a few months and I don’t use them as much as I thought I would in favor of going to the fish store to get my water tested. They were all used a few times but have all parts including the boxes and some have the sleeves. They are $50 each...

Hey guys so I had a velvet out break in July and since then my tank has sat empty of fish and I plan to keep it empty until the end of September to be fully safe. But I have a question of when adding fish I don’t want to add them all at once and then they all get velvet again even though I’ve...

Don't really know where to put this. Sorry if in wrong spot. I started cycling my tank 3 days ago. I used 3 32 Oz bottles of fritz zyme 9 (needed at least 2.5 bottles but just dumped all 3) and Dr tims bottled ammonia. The bottle recommended me to use 4 drops a gallon. It also said 100 drops...

I asked Neptune about my trident being off from other test kits and they told me I have to test the test kits to the calibration solution that is provided by Neptune in the trident dosing solution to compare how off they are to one another. this seems very logical and a way to calibrate your...

I have been cycling tanks, both saltwater, and freshwater, and had never seen this happening. I have been cycling a new system for a few weeks now. I have been using Dr. Tim's ammonia chloride solution. Every time ammonia falls below 1 mg/L I add some more to get the concentration around 2. I...

At what point in the 4 month cycle of a new saltwater tank should I start testing & adjusting the Calcium & Alkalinity? Is it best to start immediate when you initially set up the tank? Or a few months down the road when a few fish are already living in the tank & I want to introduce coral?

Hey all, I’m 22 days through my cycle currently, and am experiencing ridiculously high nitrites, so high my Red Sea kit can’t read them properly. I seeded with Dr Tim's one and only, and am testing with all Red Sea test kits. My ammonia has started to drop, nitrites have soared, and nitrate is...

Just got some new hanna checkers today and tested high range nitrate. The result was too high to read, and the instructions say to dilute it if that happens. I cut the sample in half and added more water, same result. After a second halving I got 52! This result seems ridiculous as I'd expect...

I just got my results back. I took my sample the same week that I started a chaeto reactor so know my nitrates and phosphates will come down, but am concerned that my nitrates are 135x my phosphates instead of about 10x like I see being ideal. I’m thinking of starting to dose NoPox but am unsure...

Hello fellow saltines, This is my first time doing a magnesium test. I bought the Salifert test kit. There are no coral in the tank yet and I don't do any dosing. There are a couple fish and at some point I want to keep softies. The test gave me 1200 ppm. Should I raise this with dosing if I...

So I’m new to the reefing chemistry but I just tested my water and these are the results I got. Are they good and what’s the level they are supposed to be at? *Syringe tips are over the results I got

I recently purchased a 65 gallon Red Sea aquarium on Offerup. I currently have a 32 gallon Biocube stocked with 4 fish and I am planning on transferring these fish into the new tank. However, the nitrates in this new tank are fairly higher than my Biocube (40 ppm versus 10 ppm). Is this too big...

I made a large water change today, and thought'd it be "fun" to compare results between the new Hanna Nitrate High Range 782, and the old Low Range 781 using the dilution step. 781 Low Range diluted 782 High Range Percentual Difference Before Water Change 24,9 33 27,9% After Water Change...
