A little help please

[dave creasey]

Hi
I have a 200 gallon planted tank and am just about to jump in to the wonderful world of co2. I will be using a pressurized system and probably rig it up to a ph controller. My problem is that the tank is filtered by 2 Fluval fx6s and the large hoses on these make fitting an in line diffuser or reactor tricky and if successful and not leaking would greatly reduce the flow, it has been suggested that Isee can feed the co2 straight into the filter intakes, given the capacity of the filters and the fact that they regularly self purge this would seem the most straightforward and efficient way to introduce co2 ,but not everyone seems to agree.
Any help or further thoughts would be greatly appreciated.

Having used twin FX6 on my 500l (100gallon) tank I may be of some help.
Having the Injection prefilter wont work well as filter will fill up with CO2 then 'burp' out the buildup.
Post filter works well, but needs a bypass to keep flow maxed out. I did it with solid plastic tubing with inline diffusers at first then moved onto CO2 reactors.
More detail is in my Journal

I have an FX6 and FX4 on my WaterBox 6025. I’ve never, ever used the stock hoses.

Made a standard Cerges reactor with 1” barbs, 1” ID hose. I’m running a reactor, UV and DIY in-line heater on them. Nothing in my tank but the inlet and outlet pipes.

I have been picking away at this project for a little while: building a light mount, gathering equipment, etc... Just this evening I was finally able to get the tank itself onto the stand (it has been in the garage waiting on sufficient muscle and planning to make the move into the house). I...

DIY Inline Heater with Temperature Controller

I'm currently in the early stages of a new tank project. The new aquarium is 130 gallons with canister filtration, and I want to have inline heat. Unfortunately, the inline heaters I have used in the past (Ista brand) have a new design that utilizes a staged 1/2"-5/8" barb that would be overly...

Critique my Cerges Please

My regulator has been shipped and my water filter housing is already here, so it is time to design and build my Cerges reactor. I'm very familiar with the famous post 770 outlining all the parts but I've also been shown by @EmotionalFescue and @Immortal1 the reasons behind a bypass valve and a...

And, finally, here’s my UV, CO2 reactor, CO2 tank and gas flow meter, all working with my 1” hose. Next time I build a reactor I’m going to combine it with the heating element and probe.
