Need chiller for a 4 feet planted tank?

[Filet-O-Fish]

Hi,
My current 4 feet rimless planted tank is running with a chiller set at 25.5 c.


Temp of water direct from tap: 32c
Temp reading of 12 litres of water in a container taken after 3 hours : 30 c

Can I run my tank without a chiller?
I think the fish and shrimps will do fine. But I don't know about plants.

Can the members here give some points on what are the cons and pros.
Thank you.

The tank contains the below:

Tank Vol: approx 280 litres
Filters: Eheime 1200XL - 2 pcs
Lights : 6 pcs T5HO lights hung from the ceiling with a gap of 15-20 cm between lights set and water surface.

Fish:
Tetra fish - Rummy nose, Diamond tetra, Cardinal

Shrimp:
RedCherryShrimps, Yamatos

Others:
SAEs, Otos, snails

Plants:
Christmas Moss
Monte Carlo (carpet plant)
Staurogyne Repens
Lobelia cardinalis ‘small form’
Limnophila aromatica
Alternanthera reineckii 'rosaefolia'
Hydrocotyle verticillata
Ludwigia palustris
Ammania sp bonsai
Alternanthera reineckii 'Mini'
Hydrocotyle leucocephala - Brazilian pennywort
Hygrophila balsamica

Given the list of plants you have, I'd say no chiller is needed.
Contrary to what you said, your RCS may not do well at 30 degrees celsius. They may survive but may not breed. 28-29 will be more comfortable for both flora and fauna.

It is good to have a chiller.

Hi
Thanks for your reply. Ok, since my chiller is set at 25.5 do you think I can increase the temp to 27 or 28 c?

I've read on the net that, cooler temp slows down algae growth, retains Co2 in the water far better that warmer waters. Do you have any idea about this?
Cheers.

yes cooler water dissolve more CO2 but it does not really matter because even at 30C CO2 solubility is much higher than 30ppm. Plant require only 30ppm CO2. Thus even at 30C as long as you inject CO2 you wont have problem reaching 30ppm.

Cooler temperature slow down plant metabolism, less requirement, easier to control.
