What do all algae (and cyano too) need to survive? Nutrients. What are nutrients? Ammonia/ammonium, nitrite, nitrate, phosphate and urea are the major ones. Which ones cause most of the algae in your tank? These same ones. Why can't you just remove these nutrients and eliminate all the algae in...

So im 30 days in my cycle and my ammonia is 0 ppm. My nitrites are off the chart but I read that for reeftanks nitrite / nitrates are not toxic for fish anyways. Should i wait for my first fish till nitrite is 0? Should i waterchange and get my first fish? I used the old school shrimp method to...

Hey all, newbie here. Hoping to learn what's possibly going wrong (if anything) with my current attempt to pre-cycle some caribsea life rock. I've got them in a 10 gallon brute, 2 wavemakers running for circulation, heater at 78, does Dr Tim's ammonia to 2 ppm, and added 1 oz of Fritz 900...

Tank stats 40gal breeder Live sand Dry rock Dr Tim’s cycle and ammonia followed exactly what he said It’s day 17!!! And nitrite won’t drop. I did a 50% water change yesterday and added 40 drops of ammonia just to give the bacteria something to snack on and it was gone the next day but nitrite...

Hi, Tank is about 2 months old, has 4 fish (regal tang, 2 clowns, cleaner wrasse & dottyback) plus clean up crew. Can’t seem to get the nitrates down at all and it’s never been where it should be. Ammonia & nitrates ok (0.05 & 15-20). Nitrites have always sat at around 0.5-0.8. Question, if...

Hello I’ve been cycling my 40 gallon tank for more than 2 weeks. My ammonia has been around 0.25 for the past few days while my nitrite has been 0. My nitrates is 2.5 and it’s slowly going up 0.1-0.3 everyday. Is my tank ready for fish and should I do a water change?

Hello, I’m starting a new 40 gallon tank and I’m wondering if I can use live rock as a source of ammonia so I can add Dr Tim’s one and only nitrifying bacteria. If I can should I add the bacteria immediately?

Hey everyone, I'm seeking some insights and guidance on my reef cycling process. I initiated the cycling process on March 18th, which means I’ve been cycling for approximately 47 days now. Once the ammonia level dropped to zero on April 3rd, I began testing for nitrite. Currently, there are...

Hey all! Been cycling my tank and it’s been all good up until the last 2 days. Nitrites are at 3ppm and nitrates are at 40. Nitrites had been consistently falling from 10ppm until yesterday. My tank processes ammonia in about 24 hours when I dose it up to test which I did for the first time...

I’m about 2 weeks in to my cycle that started by dosing 1ppm ammonium chloride and used Dr tim’s one and only bacteria. when ammonia dropped to 0.25 each time i redosed ammonia waiting until it got broken down fully in 24 hours. My nitrite started to rise on day 2 and continued to (my salifert...

I recently bought an imaginarium test kit. And every time I test for nitrites I get a purple coloration instead of the blue colorations that this test kit says I should be getting. It could be an accident on the part of the packaging that includes the legend. But I'm not sure. for reference...

So I need to clean my filter, not necessarily replace media just carbon. Last time I changed the carbon I noticed a lot of gunk in there. I have a fluval 307 canister and I’m deathly afraid of cleaning it because of wiping out the bacteria and I don’t want to have a nitrite or ammonia spike...

Hey guys, I’m currently doing fish-in cycling of 2 tanks (not by choice). I came home and my mom decided to completely clean my 65 gallon tank and set up my new 125 gallon tank. So when I came back home, the tanks were clean and she separated my angel fish in between the 2 tanks. I quickly...
