Hi All, I have just finished doing some work on my fish pond,now I need to plant up in the fixed planters,problem is the amount of aquatic soil I need about 8 to 10 bags, approx £80 to £100. I was told by a member of staff in an aquatic center to use John Innis no1 for seeds as it was just as good and about a 1/3 of the cost,any comments please,Thanks Reg
