Brutal honesty
I’ve done plenty of nano tanks and never had one as disastrous as this one. I’ve always done AIO’s or just a rimless tank. I keep them simple with ato’s, consistent water changes and good flow. I’ve grown sps in a 3g picotope.
I think I can chalk this disaster into two reasons
-over kill equipment for a nano
-not dedicating time into the tank once my son was born
In that past I’ve always kept the nanos very simple, this tank I tried throwing a fuge on it with probably too much chaeto. There wasn’t enough nutrients for the chaeto to absorb and to much lead to die off and nutrients in the tanks. I used a nice light for the tank for a pretty cheap one for the fuge, that led to algae in the DT and not where I wanted it. I think had I not drilled it and done exactly the same techniques I had previously used, this would of been a completely different story. Or even just holding off on the chaeto and waiting till the tank had a bigger bioload and it was needed.
As for the not putting the time into it, honestly my son is an excuse. It doesn’t take much time to do a quick water change. The tank sat so low that I couldn’t get any suction from my python connected to the sink. That made water changes a huge pita. Then I just let it go.
My lesson here and maybe something others can take from.
When starting your tank plan for your expected bioload but know you may implement things Later as the tank cycles and Bioload increases. Stay simple if possible and don’t over complicate things, especially if you know you have a process that works. If it ain’t broke, don’t fix it!
needless to say the tank has been torn down.
