People have been asking me what you need in order to keep Discus happy, and before I bought my Discus I asked the same questions.
Here is my list of things that are needed for a Discus tank.
#1 Discus are very particular about maintaining the proper PH level.
To help with this and keep my PH from jumping around I use Seachem Neutral Regulator 1 kg.
#2 This is a product that I use in all of my aquariums during water changes.
#3
I use the emperor bio wheel filters in all of my aquariums and have nothing but great things to say about them. This is a product you definitely want to buy online since I have seen the 400 at a local pet store for more then $100 and you can get it online for under $50

Okay to be honest things can go wrong and if you are going to ask someone for help they are going to ask you about your water so you have to have a good test kit. Of course regular testing of the water quality is always a good idea. I recommend the Tetra Deluxe Laborett Test Kit It has about everything you need and you will find most fish keepers use Tetra as the standard.

Okay now its time to get serious if you want your fish to be happy you are going to have to break down and buy an RO/DI filter. I bought one about 2 months ago and have seen better colors in my fish and had higher percentage of fry survival then ever before. I recommend getting the Pinnacle+ Series Replacement Membrane 100 gpd - mfg #3022

Discus are pretty picky about temperature so I am picky about my heater. I use the Top Light Heaters 200W This is simple to set you just set it to the temperature you want and that’s it. I believe these are on clearance right now which reminds me I should buy a couple more. One of the other great things about this heater is I use the 200W in all different size tanks but since it is so accurate it does not matter if it is a 75 gallon or a 10 it keeps perfect temperature.

Well the last thing is not something to buy but it is probably the thing that will take most of your time water changes. I do a 50% water change 2 times a week so if you do not like water changes Discus may not be the fish for you.
A word about Discus in summary
Overall I love my Discus but they do take a lot of care. I have heard some people start a Discus tank as a get rich quick idea but it is a lot of work, and unless you are dedicated to giving you fish what they need to thrive you are destine to fail.

Haw anyone else had problems with heaters that won’t go high enough, or won’t maintain a consistant temperature? I’m on my 3rd one now, and I’ll be taking it back today to try a different brand, and maybe a higher wattage.
Love the discus information you shared Jeff. I might try Top Light for my heater.

Sue P welcome. We haven’t had too many problems with heaters, but we did have a Top Fin heater go from it’s normal temperature of 78F to 86F a couple of months ago.
Fortunately all of the fish were fine, but our pair of Bushynose plecos hasn’t bred since then, and I read that higher temperature can make them stop breeding. Hopefully they won’t stop forever.
We already had one Top Light heater at that time, and since Jeff was really happy with it he bought several more to replace the other ones we have.
We do have an older Neptune heater in one of our tanks, and we’ve just been trying to increase the temperature for a day or two, but it hasn’t gone past 78 degrees yet - so we probably do have a heater that doesn’t go high enough, but I didn’t notice it until now because we’ve always had that heater around 72.

Actually we have had troubles with a few heaters but I am very happy with the top light. I have 200w top lights in 5 of my aquariums and might order some more and get them for all of my aquariums. They are very easy to set and it clicks for each degree you turn it up or down and it also tells you the temp it is set at. It takes a lot of the guess work out of setting a temperature and as i mentioned they are still on clearance at doctors foster and smith. Who I have always been very happy with. I have actually even used their return system twice and it is very easy to do.
