Right so i've left the tanks and inhabitants for well this long simply because i dont want things to die off if i can help it and people have said leave it a month after establishing a tank before adding shrimp. Other than doing normal maintenance and transferring the 2 liters of old water from the small tank to the large each time and the large tank then getting an extra 2 liters of mineralised new water. Friday i sorted out all the tank decor in both tanks and adjusted the tank TDS to within 5TDS of each other. mainly because i needed to cull the flaoting plants which in the large tank the frogbit has taken over and in the small tank the water lettuce had almost taken over. the Duckweed has all but died out in both tanks not that i have done anything to aid it. my tanks now look like the attached. i then took readings they are as follows:-
Small tank
TDS - 232
Temp - 23C
PH - 7
NH4 - Unreadable
N03 - 1PPM
N02 - 0.05PPM
P04 - 2PPM
dKH - 2
dGH - 6
Large Tank
TDS - 237
Temp - 24C
PH - 5.5
NH4 - Unreadable
N03 - Unreadable
N02 - Unreadable
P04 - 1PPM
dKH - 1
dGH - 5
So the Phosphate is up but thats because i was massively invasive in the tanks and churned up the fertaliser i have in the tank substrate. The PH is also what i would consider to be completely off
also as a side note its worth mentioning that stressing plays out seems to stimulate them to give birth, i now have an extra at least 3 fry appear in the tank just after the works when the mothers had seemed to have stopped giving birth.
i also got a new fish the in other breed of platy because the fish keeper at my LFS told me they could interbreed and it might make what im doing with the fish go faster, i got him today and named him Rodney and am about to add him to the Large Tank with Tyrone before taking Tyrone out and putting more females in the tank with Rodney to let nature take its course. the Fish keeper did tell me to drip acclimate him however as the PH shock may be too much so that's what I'm currently doing and he's on his 2nd dip.
that does make me wonder however can i now add shrimp to the tank or is the PH going to be a massive problem. i estimate i have between 60 and 100 shrimp in the small tank and want to transfer over say 10?
