Still Stuck, Stuck, Stuck, Stuck..........

Whichever is easiest. It might be easier to do it the day before as you'll need to get the temp right for the fish.

Day before is good, i can re test everthing on the day then ; ) Hi fishcake thanks for the message, i had intended getting 6 - 8 all male Platy, mmmm think very carefully before you impart me any bad news on that matter   

I will re read up (is it anal fin shape)? the shop i'm buying from are a very experienced and longstanding firm (if a tad arrogant)  and i think would correct any errors as they have been helpfull in the past.

Once you know how to sex them it's easy to tell!!!  you'll probably be ok with all boys. I had four males in my tank and as long as they have their own space they are ok. my boys were in a small tank so I did get a fair amount of chasing and pecking order sorting but this is normal for fishies in a tank as they can't ever get fully away from each other. Just make sure no one gets bullied more than anyone else. If you do have problems you'll just have to get a bigger tank!!!!!! 

Well Day 40 dosed the tank with Ammonia up to 2.00ppm yesterday, and it's still 2.00ppm today, so not being exactly gobbled up is it : ( ah well test again tomorrow.

Tank is constant 30 degrees Fiona, well as i may be putting fish in next week, (would rather have known tank was cycled and ready) i am checking regularly, if Ammonia isn't going anywhere its a worry as i gather cycle isn't done till you get 0 Ammonia reading?.  but we will see today, may do full lot of tests tomorrow. If my Nitrite did spike on day 31 -33 and my Ammonia was at it's lowest then maybe that was nearly end of cycle?  just hope i do have bacteria, for the fishes sake 

Oops forgot to label my axis! Axes??

Lol, does it adequately reflect the rollercoaster of emotions of your fish less cycle?

Looks like you're getting there AM 

Day 1 Ammo = 0.25 Nitrite =0 
Day 2 Dosed tank with Ammo up to 3ppm
Day 5 Ammo = 1.00  Nitrite = 0.50
Day 8 Ammo = 0.50 Nitrite = 2.00  added Ammonia up to 3 ppm
Day 10 - 17   Ammo = 2.00 Nit = 2.00
DAY 17 did 25% water change   
Day 17 - 20  Ammo = 1.00 Nit = 2.00
Day 20 did 50% water change Ammo = 0.50 Nit = 2.00 added Ammonia up to 3.ppm
Day 22 -26 Ammo = 2.00 Nitrate didn't test. Added 9ml of waterlife bacterlife
Day 27 Ammo = 2.00 Nitrite 2-6 ppm did 50% water change
Day 29 Ammo = 1.00  Nit =  2.00 Added old filter sponge from recently cycled tank
Day 31 -33 Ammo = 0.50  Nit = 2-5 ppm Added Ammo up to 2.0ppm

Day 34 Ammo = 0.50-1   Nit = 0.50
Day 35 Ammo = 1.00      Nit = 0.25
Day 37 Ammo = 1-2       Nit = 0         (first 0) Added Ammo up to 4 ppm
Day 38 Ammo = 1.00          Nit = 0      Nitrate = 20-40 ppm
Day 39 Ammo = 0.50 -1.00    Nit =  0 Added Ammonia up to 2.00 ppm
Day 40 Ammo = 2.00         Nit = 0
Day 41 Ammo = 1.00
Day 42 Ammo = 1.00 (still)
Day 43 Ammo =  0.50
Day 44 Ammo =  0.25    Nit = 0- 0.25  Did 90% WC
Day 45 Ammo = 0 Nit = 0   Bought two Platy's   (want to woo hoo! but not till i know if they survive)

If my newly installed fish were to show signs of distress (not sure what that might be)? would it help to tranfer them to another recently established tank (sisters) or would it be too late (assuming she would allow em in)
