help please diy inline defuser on fluval 405

Ok this is my first tank period lol . I started with a planted tank it's a 36 gal bow front tank I'm running a fluval 405 that's rated for 75 gal tank because I got a good deal on it. I have led for lights but any way I'm having issues because of lack of co2 so I bought this co2 regulator https://www.amazon.com/gp/aw/d/B00AJ...A3IEO85BEVOS5E and a 5 pound co2 tank I want to build a inline defuser but I'm so new to this I need some help please if some could just guide me in the right place that would be so awesome thank u

Here is a Rex grigg style reactor that I recently built for a filter with a 1/2" hose. This style seems to work really good on tanks under 100g or so. It's 2" PVC And about 20" long. Let me know if you have any questions.

Another thought comes to mind. That Fluval tubing is not very good for inline equipment so you may have to go down the the hardware store and replace it with standard vinyl tubing.

NO bio-balls, gravel, or sponge - just keep it empty. Make the straight portion a long as you have room for it - minimum 18 inches. Keep it vertical and the water flow from the top downwards.

Make sure none of the hoses can come off. Have a no-return valve after the bubble-counter on the CO2 line to the reactor.

If you have a choice, you have a problem, till you elect your choice. No choice, no problem, only consequences, learn to live with them.

non-return valve = check valve, yes.

Nope no need for bioballs. As has already been said, keep it vertical, water enters the top leaves the bottom. Use hose clamps to keep your tubing on the barbs.
