Purple non sulphur bacteria update with the extra sunlight they all did something. The green one is interesting one of the other large ones with the largest concertration of bacteria did that before turning reddish. Hopefully now the lab shed getting finished I will see if it's green sulphur bacteria or just some algae.
In total to buy that in the small bottles before for Β£35 a go would probably be getting on for about Β£800. Cost of production is probably a couple of quid.
