joining multiple tanks
here is the story so far:
I have some tanks already set up and (to some peoples dislike ) have kept aquiring new tanks.
I want to somehow join them all together using a sump system so I dont have to keep buying new filters and heaters every time I get a new tank.
The tanks are all different sizes (15gal-1gal) and are set up at different heights on the rack.
I tried setting it up so the water syphons down from the top tank the the next one and so-on until it reaches the ground where there is a sump and a submersible pump pumps it back the the top tank.
BUT I found it too difficult to get the flow rates of the different syphons and pump the same and one tank would overfill or dry up and it was very painful to do.
has anyone got any ideas??
Filteration is not really the issuse as box/sponge filters are easy to make and cheap to buy. it is the heating that is the problem as I cant heat the whole room.
Unfortunately for you trying to balance flows from different sized tanks at different heights is not something you can set and forget. In fact it's something I'd strongly recommend. The balancing act you'd need to do is just asking for trouble.
Also, by linking your tanks together you are making it easy for disease to travel from tank to tank. Instead of one tank coming down with something they all will.
I'd strongly recommend against such a set up.
how ever there are ways around this
like having a 12gallon is separate for quarantine perpouses
im interested in how you are syphoning from tank to tank the only way i can see this working is with overflow boxs which will only let the level drop so much check my tank pics to see how the water is taken to my sump as for heating heaters in sump and maybe one on the middle tank in the system if the last tanks are not hot enough
my tank pics are here
main DT - 39 gallon Freshwater fish tank
Perhaps you should talk to the LFS, as most use a centralized filtration system.
As an alternative to drilled tanks or siphons, consider a pvc overflow. Here UaruJoey has what looks like a winner:
The overflow from upper tanks could flow to lower tanks while the lowest tank(s) flow to the sump, then pumped up to the upper tanks. If/when the pump stops, so does the flow (unlike siphons).
Food for thought anyway ;-)
mine is the same can have power cut with no bad water level changes or floods
but a little more costly with :
overflow box = £30
19mm tubing = £10
25mm tubing = £13
Build cost = £53
Flow Rate = 1200 (Lph)
would go for the pvc tubing anyday
nice bit of info this :D
