Maybe co2

I was thinking of maybe adding co2 and have been doing lots of reading. I can't afford an expensive system. Out of the question. I ave a 50 gallon and would do DIY but I have read that this is good for less than 30 gallons and I have a 50 gallon tank. Then I saw an inexpensive system at my favorite aquarium stow but it said it was good for up to 40 gallons. I just want to add a little. I don't think I need to go "all out". Does anyone think that the one for up to 40 gallons would be good even though I have a 50 gallon tank? Would I be better off with doing DIY?

I would do 2 DIY systems. Just put 1 on each side, so it gets all over the tank.

I really don't want to have a lot of clutter from co2. I was using Excel but it melted some of my stem plants. I am starting again with the FlorinAxis since this is a bioavailable carbon source in liquid form. Hope this will help.

So...I have been reading and watching A LOT of videos regarding DIY co2. Few questions...(disclaimer: I know that any answers to my questions would be from your experience and may not apply but I appreciate input.)

1) I am sure that DIY doesn't produce as much as a pressurized system but could running it 24-7 cause an overdose of co2 and suffocate fish? I don't see how I could take it off at night and keep the mixture safe. A 2 liter bottle can only handle so much pressure.
2) I am planning on putting my diffuser under my filter. I have seen this in quite a number of videos with the suggestion that when the co2 bubbles go through the filter it helps keep it in the tank longer. Is this a good idea?
3) I am debating between using an air stone and a glass diffuser with a ceramic disc. I am pretty sure that are both cost effective. Would the glass diffuser have more of a potential to overdose by running 24-7? I ask because I have learned that the smaller the bubbles the more you're able to keep in the tank.
4) If I hooked up 2-2 liter bottles and made a bubble counter with a 20 oz bottle as one system would this be enough to do my 50 and my 10? I don't think that my husband would like all these bottles around. He didn't seem too thrilled when I told him that I was doing this to begin with. He doesn't understand the need for multiple tanks either. Yesterday I took my 35 gallon hex out of my friend's basement because she is moving. I have no stand for it because the basement flooded and it got ruined. I have no place to set up it and he is not thrilled about storing it in our 1200 sq. foot apartment. You all know about trying to keep your spouse happy while you expand your collection.

1. No. You will never OD CO2 with a DIY at that tank size. I inject CO2. Normally, the drop checker turns green within 30 minutes after injection starts. Few months back, after a water change, I plugged heater on timer and solenoid instead of heater. I realized my mistake after 4 days. Drop checker was yellow and plants were producing excessive amounts of oxygen. Fish didn't noticed anything. I was probably close to 50ppm CO2, maybe more...

2. Yes. If you don't mind the noise. Some people report impeller's damage.

3. Ceramic disc requires a bit more pressure to work but is more efficient than an air stone.

4. Any CO2 is better than no CO2. Our spouses almost never understand out hobby.

I was planning on getting a co2 monitor. I guess this will help make sure I don't overdose.

I use an AquaClear and I believe the impellers are a fairly inexpensive replacement. As long as it doesn't effect the motor itself.

Would the ceramic disc extend the life go the mixture?

I have warned him that when we buy a house a 100 gallon tank (at least) will be featured.

If you want a 100g tank you should have warned him that you want a 180g, so he can finally agree to a 100g. That's what I do...Its called "negotiating skills"

LoL!!

He is really good about eventually giving in. I just have to be careful not to take advantage. He has also started to show some interest. Not in maintenance and stuff but he has been asking questions. Doubt he'll ever do a WC but once or twice he has fed when I was away.
