Hi all......Firstly, let me give you some statistics.... Tank..Wave 15 (ltrs)...temp.. 22.5C..Aeriated 24/7.. Filtered 24/7.. black gravel, lights 9hrs per day. Well planted with various Amazon swords and Cryptocorenes (which I read somewhere are r
eputed to have poisonas roots?) ph-7.3=7.4..Ammonia..0-0.25...Nitrite..2.0ppm.. Nitrate..0-2.0ppm.
Hardness not measued but led to believe medium hard.The tank was set up some month ago and initaly with some neons and cherry barbs to stabilize the tank. After 3 weeks the fish were removed to my other tank and 2 RCS and 3 Cherry shrimps added. These gradually died over a period of a week and since then replaced with Bumble bees,further RCS but all slowly died now the tank is a grave yard.
The losses themselves are bad enough but not knowing why the deaths is worse.
To my mind the reason can only be due to one of the following... the gravel (black so must be coloured some how)..one or more of the plants..water (changed twice a week)..the small tank or "act of God"
I realise that with a small tank such as this it will be difficult to stabilize the conditions. The maximum number of shrimps at any time was 5/6 and the shrimps were all obtained from four sources. Now what the blazes is going on.. is it that difficult to keep shrimps and just what are ther required parameters to I do not wish to kill any further shrimps so any help and advice will very gratefully received.
