Right, so we now have:
for one month and for a 400 litre (88 uk g) tank
Fluval lab grade 150g will do a 75g US tank for a month about £11
Rowa 500g approx £23 approx half of that for a 400L tank ao, approx £11 (although, im getting through 500 g in approx six weeks)
tanktests phos remover 1000 ml - 500 for a tank my size, cost £16 so approx £8
postage needs to be added if buying online
