Ct 5ft planted tank

[Flowerhfanatic]

I block the under flow from the top of the tank, sand will not suck into the tank.

Regarding the amount loss using sump tank, many answer to it bro. Bigger surface area will loss more.

I can only share with you my experience.

My first 5L tank last only one month with the below setup:

1. Overflow with bio-ball inside. (CO2 loss, as many air exchange in this area)
2. Lots of splashing into the undersump. (CO2 loss)

After reducing the flow rate, minimise the splashing in the sump, took away all bio-ball in the overflow system and convert to normal overflow.

My 2nd tank was top up on 28 July, now still around 70 - 80%. Counltess bps, can't count as too fast.

It also depend you usage of the CO2 bro, so very difficult to say.

Hope this help.

sounds complicated. guess i should stick a more simpler 3ft set up.

not really bro, don't give up having sump tank. They are much easier to maintain than canister.
