HELP!!! Tank wiped out 15gl Fowlr tank

Hi Experts,

I need your advise, about a month ago I started this hobby and failed.

After 2-3 weeks of cycle, when my Ammonia, Nitrate and Nitrite dropped to zero I started adding 2 clowns fish and a baby BT in my tank. After couple of days, I added more and so on..

In total here's what I have within 3 weeks of starting the cycle
2 clown fish
2 watchmen goby
1 MI
1 BT
1 DotyBack
1 Firefish
2 red Shrimp
2 hermit crab

(I know it's too crowded. I got excited)

I have a huge live rock, live sand, mechanical filter and powerhead. I also do 10-30% water change every week and every other day vacuum if a lot of food remains uneaten.

What could be the reason why I failed in my first attempt?

The last thing I saw is BT got ich and the clownfish got some sort of brooklynella(they are like covered with wet tissue paper and hard breathing because they stayed in the top)

Currently, I cleaned my tank removed my water(NSW), removed the live sand and live rock(Cleaned and put it under the sun for 3 days) also, I did not use my tank for 3 days.

I will start tomorrow and start rebuilding my tank so I need your help to avoid having the same mistake that I did. Thanks in advance.

BTW, I have read that successful nano Fowlr tank has protein skimmer, Do I really need this?

Hi Vinceprince,

Tangs or Surgeon Fishes are very sensitive to Ich. They also need 50gals at the very least to prosper, I suggest to have them adopted. You might have also acquired a bad quality of Livestocks. Put only 2-3 pcs small sized fish in a 15gals tank. You can do without a Skimmer as long as you perform Weekly Water Change. Hope this helps.

PS. Please do more research on the Internet.

Hi Vince,

In addition to that, when introducing livestock you need to do it slowly. This means as much as possible only one at a time, with 2 weeks to one month interval so the bacterial population can catch up with the increased bioload.

I'm not sure about your test kit..or your water testing methods but the waiting time you mentioned for the cycling to finish seems too short IMO.
