I have a Red Sea 260 that has been up and running since March 16. It has 50# of the dry purple live rock, a very thin layer of the caribsea live sand, and I dosed the tank with starter bacteria daily until it the bottle was gone as recom by my LFS and Salinity is between 33-34.
March 22 I added five soft corals, three fish and a bubble tip anemone that came out of my old tank. ( side note, the anemone is happy and thriving up top on my rock near the return and looks happier then ever) Six days later,
March 28 I got what appeared to be diatoms heavy on the sand bed. Against my better judgement I decided to suck up five gallons of water to get the ugly out and added five gallons of fresh salt water. As directed by my LFS I ordered vibrant and started dosing 6ml once a week. After the five gallon water change and vibrant dosing the diatoms seemed to rapidly fade away and now I see no signs of it. I have been checking water chemistry 2-3 times a week because I’m determined not to fail at this tank like my previous bio cube.
April 10 I added
1 neon orange mushroom
1 cactus coral (pavona) recommended by LFS
2 emerald crabs
and 3 snails
April 11 my water test provided the following results
PH 8.2
Ammonia 0.25-0.50
NO2 1.0ppm
NO3 5.0-10 ppm
I did a 10 gallon water change
April 12
PH 8.2
Ammonia 0.50ppm
NO2 0.50ppm
NO3 0 ppm
I added a capful of Prime to my tank to detoxify the nitrite (that’s what I was thinking I should do)
8 hours later I conducted the water test again and saw no change, I do realize I can get a false positive with the primesince it only detoxifies and does not remove.
April 13
5 gallon water change
April 14 (today)
water test shows all the same parameters as before.
1- I just want to know am I worrying to much?
2- are these parameters undesirable?
3- should I do something different?
the water is crystal clear, with no visual algae. Filter socks are changed every three days, and the water temp is 78. All livestock including corals appear happy and healthy. Skimmer has been running steady and collecting skimate for about a Week
i also want to add that I have no bio filter media or anything else in my sump, I have been trying to figure out if I should add some. Any input or guidance much appreciated
