Advice needed for 2 tier tank set up

[Sandfire]

hi anyone would help me wit the setup of 2 tier 2 ft planted tanks running on 1 chiller and cannister ..

pls kindly advise ..

Top tank
outlet from the chiller
Overflow pipes to the bottom tank

bottom tank
Inlet to the cannister

Cannister : outlet to chiller

Specification :
cannister : 800/litres hr
chiller : cl280

I am still wondering .. does overflow counts as an filtration ? can my equipments able to support the tanks requirement ?

How can i improvise ?

thanks in advancement ..

a few points I can think of:
1) I'm using a CL280 to chill my 2 feet tank...... your 2 tanks are equivalent to 4 feet tank...may be a little underpowered. I expect alot of "heat gained" from the 2 tank setup.

2) your cannister is underpowered as well especially with your kind of split setup

3) your water flow is going to be a big problem, especially for the lower tank as there is no way to properly direct your water inlet from the overflow.

4) your CO2 (i asssume u are going high tech) usage will be massive from the overflow.

5) overflow in this case is not a filtration as there is no media being passed through. your cannister is the only filtration.

thanks for your advise ..

I have space restrained .. currently having a 2 ft tank, trying to fully utilised the space. i wish to have 4ft tank too..

So is best to have 1 cannister to each tank for filtration right?
If i get a better chiller , can i still support 2 tanks using same chiller ?

u were saying usuage of co2 from overflow , does it mean that co2 will flow down with the water and overdosing the bottom tank ?

Is there any solution for 2 tanks with 1 cannister and chiller ?

A chiller (as far as I know) only have one inlet and one outlet. So these is no way it can support 2 tanks unless they share the same circulation (ie, either running in series as what you proposed above or in parrallel when you join the 2 outlet from the 2 filter cannister to the chiller and split the return to the 2 tanks....possible but a headache to control the exact amount to return to each tank as any imbalance between the intake and output will just mean one empty tank and one overflowed tank)

I meant that the co2 lost from the overflow system will be alot and you have to inject alot more to compensate. [assumption: you are using chiller so I assume you are going high tech planted? If high tech planted, usually means CO2 injection and high lights]

suddenly a solution came to me..but with your space constraint, it may not be feasible.

the 2 tanks have to overflow to a single sump and you draw the water from the sump into the chiller and return the water to the sump or both tanks.

oh ok .. thanks

will try to work on it ..
