Hi guys..been off the site for a while keeping busy with my new project and now i need a bit of advice from the experts out there...I was lucky enough to get a nice big new tank and sump for X-Mas +\- 650 L as an early gift(bought enough jewelery for the wife!...maybe they start feeling guilty). Filled with sand and RO, got SG right and then added some of my "old tanks water and moved over some LR. It has been running since start december and i have only done "small" water changes...not even a whole 10 % /week. End of december I moved my softies and my 3 fish (1x lawnmower blenny, 1X P Volitans & 1X dwarf lion). up to now my water paramaters have stayed the same...with only ph fluctuating between 8.4 & 8.6, the rest is within spec (even a bit too "sterile"..no PO4, NH4, NH2, NH3 etc etc) thus my question...should i start with the "normal" water change regime..or stay going at the rate i am and just keep an eye on things ?
