Hi thanks for the nice comments i introduced 6 cardinals and cherry shrimps after about a week and only got 3 cardinals left but have alot more cherrys then i started with. The chemistry never really changed but was doing water changes every otherday but now do it once a week but i do have the light on around 10 hours a day but i think its better on for around 6 if i remember right from the advice i gotHi, looking good mate , I see you have introduced your livestock, how long did you wait before doing so? Has the soil you used affected the chemistry of the water? I am setting up a similar tank but need to introduce my fish etc asap. Carry on updating this one please ,should be good to see it progress .good luck!
