I would never advising using more than 12% peroxide and use 9% with 2 catalyst myself in the sump of my RSR250.
Your tank is a similar size to mine i have a W model which holds a litre of the 12% hydrogen peroxide I use with 2 catalysts, with no issues whatsoever. I have a nem and keep predominantly sps, my rock is covered in small sponges and tube worms, I’ve not used any carbon in years and my tank has no yellowing whatsoever. The catalysts according to sochtings website will last indefinitely, mine look like new still after a few years. A litre will last about 6 weeksHey - I'm glad you replied - can you recommend (I'm not sure why the correct instructions did not come with my oxydator) - I have an RSR XXL 750 - what would you recommend. Thanks - and BTW - it's not mentioned in the instructions - how often (if ever) - do the catalysts need to be replaced)?

What would the effect of running 3 percent hydrogen peroxide be? More frequent refills?
Lower strength peroxide reacts with the catalyst at a slower rate. If you use 3% peroxide you will refill “less” often than you would with 8 or 12% strength solutions.
But whatever results you were hoping for will be reduced by the same duration - right? - I have one - I use 12%
Right - its chemistry - by the same logic I could lower it to 1 percent - and save more. In reality - the less you use - the less effective it is - the more you use - and above the recommended dose - the more toxic it is. OR?I use 12% with two catalyst in a W model. I can’t see lowering it just to last longer. It lasts pretty long as it is, and I’m getting good results.
Not necessarily as there can be a bit of art/voodoo in balancing certain variables.
For example, I was using a mini with 8% in my Nuvo 10 and getting good results. I knocked it down from 10% in order to make it last a full week. I wanted the consistency and I get busy during the week. There was no noticeable difference other than helping my schedule.
Then I upgraded the tank to a Nuvo 20 and put an Oxydator D in with 10% H202. I had a few things visibly react to the heavier dose that the D puts out, as it’s a borderline overly large unit for a 20 gallon. Lowering the concentration to 6% for this tank turned out to be the sweet spot.
This is all being moved into a 40 with a full sump next month. I expect to be back up to 10 or 12% with the D unit in this tank.
A few other things will affect it not just dosing strength of peroxide. The amount of organics in the water for one, whether you use a skimmer and how efficent it is, stocking level another and last but not least how much you feed. These are all variables and no 2 tanks are the same. One final thing with a strong solution of peroxide all may be fine before but as the water becomes cleaner you may find that the number of catalyst and strength of peroxide used becomes too much for certain animals and you may get a negative reaction from some of them.No clue whether this is transferrable - but - its all about dose - assuming its doing anything in the first place
Thanks - I'm glad you answered - I have a new one (just started using a couple weeks ago) - I dont notice huge amounts of 'bubbles' or any indication that anything is happening - how do you tell when to change the H2O2A few other things will affect it not just dosing strength of peroxide.

PS - I didnt see that @Mortie31 already answered the question @atoll -do you agree - about 6 weeks for a W with 12%Thanks - I'm glad you answered - I have a new one (just started using a couple weeks ago) - I dont notice huge amounts of 'bubbles' or any indication that anything is happening - how do you tell when to change the H2O2
I just ordered a “A” model and wondering where you guys get the 35% peroxide at?
