Newbee needs advice: diffusor / reactor or atomizer

[Solex]

Hi all..

Iam relative new to Planted aquariums and iam in the process of buying the needed equipment.
So far I have ordered in cm a 80x45x60 216l tank.
A JBL e901 and JBL e1501 external filter.

What kind of Co2 Atomizer/reactor or diffuser should I buy? I dont think I will mind the fine mist of a atomizer. Iam planning to use the spraybars.
No glass please, I am clumsy

This is the co2 set iam looking at, it has a reactor.

thank you,
Lexy.

Two filters for a tank of that size is a lot. Only the JBL1500 is enough, even with the use of the reactor. The CO2 set you want to buy could do it, but you have to change the inlet and outlet from the reactor to the bigger size of the filter hoses. If not, there will be a big reduction in flow. An atomizer doesn't have that problem, but the ceramic diffusor disc tends to clog over time.

Also buy a simple timer, to turn off the CO2 at night and a "CO2 continu test" Dennerle has a nice one.

The tank is 216 liters, Ive read that I should try to cycle every liter 10 times a hour, so that would be 2160 l/h.
The e1501 does 1400l/h plus the e901 900l/h. is 2300l/h.
So in theory it should be to much but the filter media/atomizer would slow it down I guessed.

I can always return the extra pump, its still in the mail.

I will check out the dennerle test and add it to my shopping list, thank you for your input, keep it comming please 8)

10 times is on the high side, because your tank is kind of small. A filter makes a high pressure outlet, you might have problems keeping your plants standing up. But you will notice soon enough.

With a tank of your size I would not go further than around 6x the volume. Best way is to find out I guess

Is there really a problem with over filtering in a planted tank though? Just wondering

 

[Solex]

Ive read that it can mechanicly stress the plants if they overextend or move to much.
But its up to the plant species and how the flow is set up I guess.
I did not unpack the JBL e901 and will return it to the store, also bought the UPAqua diffusor.

Overfiltration? I think it's mainly aesthetic.

on my 4ft 55gallon I have about 600gph of circulation and it is manageable; this is with a venturi and fractionating impeller on a Mag 7 plumbed in after the output of an Eheim 2217, plus an Eheim 2215 with inline heater. Remember also, that depending on the length of your hoses, if you have any rigid PVC/ABS 90s, etc. will have an impact on the rated output of your filters. A single rigid 90 fitting will be equivalent to multiple feet of head for head loss calculations.

I would put your filters rated output at around 60% to be conservative (take into account total feet of head, any rigid fittings or diameter changes that may be used, and that flow will drop over the course of your maintenance cycle between canister cleanings)

Planting cuttings can be challenging and you may find you will have to propagate new plants in a lower-flow corner of your tank and then move them once you are able to anchor them better.

Experimentation is the best; the ultimate goal is to have as few dead spots as possible in your water column, with as much possible water being routed back to your filter intakes. Powerheads like an EcoTech Vortech or Hydor Koralia Nano can help with this.

I don't really like in-tank diffusors. As dutchy mentioned, they become another component of your maintenance regimen as their performance will decline as they become clogged. They're also another piece of equipment clutter in the tank.
