Hello everyone ,
First thank you for taking your time and reading this thread .I’m going to be as detailed as I can ,so I hope you can bear with me. I have recently built a tank diy the whole thing. Got a 20 gallon tank cut some acrylic , converted it to an aio tank.
I bought some live rocks to speed up the cycling process and ran my tank for couple of weeks more or less. Got too excited and and got some fish and 3 hermit crabs and snails.... I over stocked my tank “big mistake“ , and to make it worse I got one of the hardest fish to take care of “ mandarin“ after being recommend by fish store.By that time I had 2 mandarin one clown fish and cardinalfish. after a week of stress trying to get the mandarin to eat one of them died. I tried everything but the other mandarin didn’t eat and died after another week. Mean while all of this was happening one day I noticed ich in the tank after the heater turned of when I was asleep and the temperature was 22 C . It went away after couple of days ... but not for so long , a week later the clownfish was covered in white dots. By that time I wasn’t sure if it was ich or velvet. The other fish had it too unfortunately.
I don’t have a quarantine tank , I couldn’t put them somewhere else and treat them . Next day the cardinalfish died .. I got a cleane shrimp hoping it help or anything until I build a 10 gallon tank I had laying around but the clownfish died the day after.
now it has been a week there is no fish in the tank just 2 hermit crabs , 4 of snails and cleaner shrimp. The tank is a month and a half old . I’m not going to add fish for 76 days hoping whatever killed the fish will die off .
green algae is covering the rocks for three weeks now with some bits of coralline algae. I have what I think might be copepods in the tank , a lot of them not sure if that’s a good thing.
Im not sure what can I do now , is it okay to add corals something like blastomussa or zoanthids or should I wait? If I can should I build a quarantine tank first and put them there or will dipping them be enough. And how do I get rid of the green algae ?
my tanks parameters are 0.02 ammonia, 0.02 nitrite (0.02 is the lowest measurement in the kit I’m using) the nitrates is 5 and the phosphate is 0.2, I’m going to try lowering the phosphate level with water change . If that didn’t work I’ll try some phosphate absorber.
while I was writing this one of the hermit crabs died he kept fight and taking the other crabs shell for a while he killed one and fight with the other one multiple times and kicked him out of his shell. I’m not sure what’s wrong ..
sorry for the long post and hope you guy’s can help.. thanks for your time ❤
note:I have been using petg 3d printed parts I’m not sure if that could harm or cause problem.
