so today was mostly about chilling and doing the little bits round the house ready to go offshore.
I decided to start my parameter diary again from scratch, i had a look at the readings and comments, all the memories came flooding back of the old tank in my hobby room.
So we're at a starting point of knowing our parameters anyway, ammo/nit are bang on, but the water is way too soft.
I'll be honest it's expected as I didn't actually buffer the system when filling it, and the temp tank wasn't buffered or monitored in any way for a long time.
My tap water TDS is only 35 here so it's a lovely soft water area.
My current GH is 5 (target 8) and my KH is 0 (Target 6).
So I'm going to dial in a small amount of Bicarb to dose slowly, and set some manual doses to do a slow drip WC over the next 48 hours, try to change out 30/40% of the tank.
One scoop of my buffer in the topup tank gives 200(205) TDS, GH of 7 and KH of 3.
With set regular changes (4lt per day) once I get the bigger tank in, I should be able to tweak the bicarb dosing to maintain a fairly consistent value.
