I am far from an expert but dont they have better filtration systems.
Hey All,
A couple videos came out on YouTube recently for Jack Wattley Discus. Two separate presenters stated they clean their personal tanks once a week with only a 20% WC.
Now, I'm not one to be dogmatic about WC schedules. I think whatever works for a given person is fine. And these are their personal planted tanks, not the crowded hatchery tanks. But still, 20% once a week seems kind of low to me.
On the other hand, these are long-standing employees of a reputable discus hatchery. I imagine they know what they'e doing.
So I'm curious, what does everyone here on the forum think of this?
I am far from an expert but dont they have better filtration systems.
My personal view of this is show me the fish. The condition of the fish will tell you the truth whether the tank maintenance/feeding schedule is spot on. So don't tell me....show me. Also this could be a selling ploy since the videos are representing Jack Wattley Discus.
I do wish Gabe would update the name of the business to reflect his own brand.

Your discus are talking to you....are you listening
I don't think filtration would matter, as long as the tank has sufficient nitrifying bacteria to convert ammonia and nitrites. After that basic consideration, it's mostly nitrates that drive the need to change water, and no excess in filtration would cover that. The exception of course being a deep sand bed or some unique set-up that sustains anaerobic bacteria.
They shouldn't give the wrong impression to people who try to get into the discus keeping hobby. All I can say is they just want more business from people all over the world. We all know if we don't keep up with the WC, the fish have a good chance of getting sick and probably not able to recover and dead. More purchase and more sick fish.....and the cycle keep going. That is very sad
My 2 cents
Stendker's website says 50% weekly. When I asked Hans he said "well 2 is better", LOL
I change small amounts every other day which in a week's time amounts to around 50%. I spoke to a local breeder in my area of angels and discus with over 40 years experiecs. He changes once a week less than 50%. Can water changes be over done as well as under done?
Timing water changes is very subjective in my opinion.
Tank size, quantity of fish and feeding schedule all play key factors.
If you had a 150 gallon tank with two adults and you fed once a day you could probably go 6-8 weeks with a 25% wc
You should be doing water changes based on Nitrate levels. Below 10ppm for adults, below 5ppm for the youngins'
My 1.724 cents
It's been interesting to see people's responses. I'll provide my own two cents to my own query.
Given the reps in question stated they keep planted tanks, I don't think it would surprise anyone that they get by with smaller WC. After all, plants consume nitrates. However even considering this, 20% weekly sounds very small to me.
I suspect the other, larger factor at play is water hardness, PH, or some other environmental factor. To clarify, I think they might be good on all other factors, so they can get away with a bit of nitrates in the tank. Let me explain further.
I personally subscribe to the one-stressor-is-OK school of thought. While zero stress-factors is of course best, I believe most fish are hardy enough to deal with one bad thing and remain in decent health. But add a second bad thing, and things go down hill. Many discus keepers require frequent WC for success because some other factor, likely unknown, is not optimal for this sensitive species, and when they don't change water the fish get sick. It's the straw that breaks the camels back. I myself, for example, have high PH water. I generally have success though because I stay vigilant on everything else, including frequent WC to keep nitrates very very low. Maybe someone else over-stocks their tank, which is a stressor, but because they're great on all other factors they still have success.
So I do think 20% weekly is too little for most people, but for these specific people it could work. I guess it comes back to 'whatever works for you'. There's simply too many factors for a one-size-fits-all approach.
Yeah, Gabe probably should've had a caveat in that statement. There are many different factors that could go into his rec on 20% WCs. Type of food, feeding schedule, types of plants, filtration, ph level, stocking level, etc. I can go 2 weeks without a WC, but I have a planted tank and low ph. And my Nitrates are 7ppm. Of course, I still do weekly 50% WCs, because I'm a glutton for punishment.
Also it depends on what you want your discus look like. Football shape, big dinner plate......
I have 21 quarter size baby discus with daily 90% WC. In less than one year, almost everyone grow to the size of over 7 inches and the smallest one still got to 6 inches.
