Here's my birthday present ready to go....

Ingredients all weighted up and ready to go.

Recipe is an old one of my mates.... and goes something like this.
Brew
4300kg Pale Malt, Marris Otter
350g Crystal Malt
150g Flaker Barley
13L Mash liquor
Hot Liquor temp: 70ºC
Mash temp: 66ºC -(Actually started higher but then setteld to about 64-66)
Mash time: 90 mins
Boil time: 90 mins
Hops :
Prehop boiler with 4g and 3g of the below.
30g Fuggles at start of boil
30g Early Gold at start od boil
10g Early Gold at 15 mins before end of boil
Irish Moss last 15 mins of boil
Aiming for OG 1044 and 25 Litres
Yeast: Sarfale 04
Went a bit worng as new kit always does... boiler was very powerful and got lovely rolling boil ended up with less tahtn tweenty litres near 1058. So made up to 20 litres and was down to about 1046.
I hope that isn't a problem.
Took some wort our before hand and with some nutrient rehydrated it... was going great guns this morning.
Not sure I sparged correctly jsut kep measuring it until is was under 1010. But didn't adjsut for temperature.... till it states like weak tea with just a hint of sugar.
In tend to rack off into a pressure barrel with some gelatin.... By receip says add campden tablets...
Question i want to know is.
1) Should I have topped up with water ? How do I know how much I need in future to get to teh correct OG ?
2) when should I rack for Secondary ?
3) Do I need to add campden tablets ?
