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 HYT
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?
