Been a while since I posted, so a quick update is probably in order.
The macro algaes all died off sadly, so went into the bin. Good chance a mixture of poor lighting and low nutrients may have played a part.
The snail is doing well, lots more algae growth in there these days, brown, red and green. lol
Still no shrimp. They've not been a high priority to be honest as we've been a bit short of cash lately. On the list for some time next year probably.
