Got the koralia 1600 in the tank yesterday, no more dead spots
. Really pleased with it, and there is the bonus of crud not settling at the front of the tank where it is so obvious. So at this point I am now dosing TPN+ and excel daily, and now with a good flow around the roots, how long I'd you reckon I should leave it to see the results? And if there's no improvement at that point, I guess CO2 is the only option left?
