Sorry for the late reply i use EROS once a fortnight 2 spray on 15 L tank.

For GRADIVAS is once a week.

Also if what are your tank parameters? If the water is not suitable for the shrimp to molt and you force them to molt of course the shrimp will die.

Again sorry for the late reply.

MY water parameters are as follows.

pH = 6.8
GH = 7.0
KH = 3.0
NO2 = 0
NO3 = 0
NH3 = 0
Temp = 24 degrees C
Vol = 15L
Water change = once a week 30% aged water treated with MOSURA ShiZhen

Thank you fo rur kind advise

My apology for late reply for all nice ppl who advise me~! I was overseas till now then back~!

ALSO 2 MORE Shrimp died~! But not as much as previously when i dose in the EROS & GRAVIDAS~!

Firstly, your tank is wayyyy to small. 15L Large water changes to such a system always causes a shock to the lifestock. As such, even without using the eros your shrimp will have problems. Also with such a small tank, the chances of overdosing is very high.

Secondly your gH is pretty high. Shrimps kept in this condition will have thickened shells. When that happens, they cannot molt and will eventually die off. You just hastened this process by forcing them to molt.

Your GH for tiger shrimp more like it you should bring it down it is best to lower your GH more unless u want to keep those tiger, blue tiger,OEBT etc.

Sorry, forgot to ask. Initially how many shrimp did you have in there?

i think like master Silane mention before as long as u maintain your water good the amount of shrimp in tank shouldn't post a problem of cause if u put 100 pcs in 1ft than there might be bioload problem. I think bro david problem might be his GH if he reduce his GH should solve the issue. Unless his water or something else turn bad. I just want to know the part where or how we determine the water goes bad or it is the soil causing the problem.

I think the small tank plus large water changes is the killer, he may experience death right after water changes. GH vs relatively high pH is a another shrimp shells get thickened and cannot molt, this can lead to death too.

Gravidas can reduce thick shell problem if the shrimp were feed with it from day 1 and GH/pH is not out by too much.

Quite large a number of shrimps can be kept in a small tank, that may have to be done with large water changes and cultivating strong bacteria by adding powered bacteria in the tank, this would require quite an indepth knowledge on water. I would advise newbies to use the smallest, a 2 ft tank for shrimps, larger tank has more room for error and larger surface/volume for bacteria growth.

Wah. The master has spoken. All newbie like me must learn and take down notes ah!

I think it is the rush that kill everyone shrimp especially when i get a tank setup and than rush to put in shrimp w/o proper cycling. Alot of ppl including me i must say find it very weird to have a empty tank sitting there hahaha. But now i learn my lesson. I will check all aspect stable before putting in commando to test water before the main convoy arrive in.
