Update:
Time for the good, bad, and ugly, please chime in with experiences, very interested to hear

1. Hair algae with no phos or nitrate readings. Clean up crew and manual removal, but have lost a couple of acros, and a couple more looking smug. Now, it is either starvation, or another issue.
Solution:
Am definitely using bacteria and carbon source, now using BW Micro bacter, 3 drops per day. .5ml a day of Aquaforest Nitraphos Minus. To combat bottomed out NO3, now dosing 5ml per day, BW Neo nitro, will monitor every other day, once target reached of 2ppm, will continue to dose until my fish population increases.
I believe some of the rock was not very clean, I most definitely know the low po4 is being consumed by hair.
2. I changed out carbon, with catalytic carbon, in RODI setup. In the past I used regular carbon pass, after sediment, before RO. With 155 TDS, I never really put 2 and 2 together, assuming that didn't warrant any additional filtration other than my 4 stage RODI unit. After several times of smelling chlorine from tap, it makes perfect sense that maybe chloramine leaching is why I have had issues with my past tank, and presumably some in this current setup. Either way, after always smelling heavy chlorine smell from the tap, I think catalytic is the way to go. Our neighboring city most certainly uses chlorine and chloramines, I dont recall on last water report, but plan to call the city soon to find out.
3. Some good news, lol. Alk consumption finally kicked in, seeing daily consumption, this is encouraging despite other issues. Some acros are showing growth. 2 days ago I changed water with 10 gallon water change using TMPR salts. Of course after I changed carbon pass on RODI. This change seems to have halted some of the poor acros.
That is about it for now

More to come
