Lily Rose Tank No. 3

[waterdrop]

Maybe John and I should place bets on whether you can hold out for a full fishless cycle this time.

Your decision really depends on if you are going to concentrate on platy breeding or not. If so, then this is what I would do:
Tank #1: adult platys
Tank #2: divided fry tank
Tank #3: betta & Snails
New Tank: cory & guppies, with room left for additions

If it's play sand then it should be okay. Can't help you with the filter or lights, sorry. It's hard to tell from the pic but is that tank a bowfront (curved glass)?

 

[LilyRose Tank]

yeah it is partially bow front. imagine corner back 90 degree angle attached to pentagon front, so its (60cmx60cm)...at back corner (16x60x16 ) at front with the 60 slightly bowed. If that makes sense, plus then the height is 47cm,as shown below, when using maths areas formulae it comes out to about 180 litres.

I am considering tank 1 guppys,
tank 2 platys
tank 3 betta
tank 4 platy fry and corys

what you think

or tank 4 will be corys and i wont be breeding for a while

Maybe John and I should place bets on whether you can hold out for a full fishless cycle this time.

I have enough equipment here for all 4 tanks, the PF4 that is in tank 1 now, will manage 40G so it may go in the tank4, then tank 1 will be fitted with its original filter which i kept the media from PF2 so hoping to only set up run for a week with testing and hopefully be cycled as the tank 1 is now overstocked and the pF4 is manging that for a few days before showing slight rise in ammonia and nitrites are 0 and nitrates increase daily, so at present the ammonia is sticking, so hopefully that filter will be ready in 2 weeks

 

[jmiller]

Sounds like you have it all figured out except for the most important part, to breed or not? If you do decide to continue breeding do you have somewhere to send the fry?

 

[LilyRose Tank]

thats the next bit of research I have to do.... The fry I have now, I have found a lfs willing to take them as its only 50, but I'm not sure if the manager would be wanting to make that a permenant setup. I also need to work out how big the fry can be before I sell them, as I re calculated the tank to be 120L/ 26G so it will hold less fish. ( recalculated from measurements taken once it was delivered this evening)

I still like the idea of a cory tank, and the filter i have can handle 40G so we will see what my brain decides on lter on, once set up and testing in a weeks time

 

[jmiller]

Well if you can't unload the fry then the decision will be made for you. Good luck.

If you use the dimensions of 60 cm and 47 cm and 16 cm you get an with a height of 47 cm I get a volume of 91 litres plus a small amount for the curvature of the front glass. If we call it a nominal 95 litres, that would make sense. I have no idea where the 120 litres came from. I used the simple 16 cm x 60 cm and added in the 16 cm x 37 cm area. After that I had the 37 cm x 37 cm x .5 to account for the triangular section. These 3 calculations gave me an area of 1936.5 sq cm for the bottom of the tank. When I multiplied it by 47 cm height I got the value listed of 91 litres. I then said it could not be much more for the rounded front so call it 95 litres.

 

[LilyRose Tank]

OK, This is the diagram I used to calculate area, and volume

I didn't want to bog people down with maths but....

therefore...
Area 1. 1/2 b x h
1/2 (84) x 49
42 x 49= .....................2058
Area 2 and 4. 1/2 b x h
1/2 (12) x 12
6 x 12=........72 x 2=.....144
Area 3 60 x 14=.......................840

area 1+2+3+4= 2058+144+840=........3042 x (hieght of tank) 47= 142,974cm[sup][/sup]3 /1000

142L divided by 4.55 = 31.2 G so it works out more than 120L as first calculated due to bad maths on my part 9 tiredness....isnt it wonderful

 

[OldMan47]

I approached it differently. I used a rectangle that was 16cm by 60cm,(area 1) then took the remaining (47-16)cm by 16cm rectangle (area2). That left me with a triangle that was (47-16) on one leg and (60-16) on the other (area 3). I then used 1/2bh to multiply those values to get the third area. If both back panes are the same length at 60cm, the answer would be different and if the short side panels are 12 rather than the 16 in the first diagram that would also affect it.

 

[Always Learning]

123.7 Litres, or 32.6 US Gallons

Or if the smaller sides are 12cm, then 115 litres and 30.3 Gallons.

I cheated and used a calculator though

With that tank, I assume you are measuring up to the glass cover and not the top? As my old one was the same tank as that and it worked out at around 100 litres, taking out the gap above the glass top.

 

[LilyRose Tank]

OK. I just measured the glass of the tank, and the short pieces are 16! Must of had a blonde day, the front piece is 62 but its a bowed glassfront. and measures 61 from corner to corner without the bow. Just doing the math again your way OM47 and.....
60x16=960
16x44=704
30(1/2)x h34( the measurement from halfway across b to point where two rectangles touch)=1020

960+704+1020= 2684x47=126148/1000= 126.148/4.55= 27.72G or 126litres (this is just approx as I didnt use 62 as the bowfront of glass so its a little more

 

[OldMan47]

I just used a different method to simplify things. The answer should come out about the same either way if the measurements are accurate.
