"I have used STS since 2011 and have been a strong proponent of it for planted tanks as an excellent alternative to most other substrates out there with the possible exception of ADA Aquasoils."

We definitely agree on that.

Hi All,

2020-08-21

Today I did a six (6) gallon water change. The tank has a water volume of 24 gallons so 25%. Here are the water parameters after the water change:
pH = 6.8
dKH = 2.0
dGH = 3.0
NH3 = 0.0 ppm
NO2 = 0.0 ppm
NO3 = 5.0 ppm

I did a light gravel vac in the front again, added 3/8 tsp of CaSO4 for 3 ppm of calcium, 3/8 tsp of MgSO4 for 2.0 ppm of Mg, and 3/16 tsp of K2SO4 for 7.5 ppm of potassium. Why did I dose those nutrients? I noticed the deformed new leaves of the Bacopa colorata which is likely insufficient calcium. I also noticed the necrosis occurring in the older leaves of the Eriocaulon 'Vietnam; likely insufficient potassium or magnesium. Lastly the Limnophila rugosa was showing interveinal chlorosis on the older leaves indicating insufficient magnesium and the older leaves of the Bacopa colorata have their leaf margins curling (under in this case) also indicating a need for more magnesium.

Hi All,

2020-08-24

Monday and today is water change day for all my tanks! I have also been doing water changes on Thursday or Fridays as well however based on input on another forum I will likely increase the frequency. Today the tank got a little over 50% water change.

This last week the fish seem more acclimated. They are no longer staying in a tight school most of the time as they were the first week or so. Instead they are exploring and foraging more individually. All the discus are eating well (and continuously) and I've upped my food budget for the hobby.

I have received a lot of feedback on the forums where I have been posting this thread that "you can't raise discus in a planted tank" or "you can't keep discus in a planted tank, when you see pictures of discus in planted tanks they are only there for the photo and then returned to a bare tank". I honestly don't know if those individuals are sharing information based their own personal experiences or if just repeating something they have heard or read. In either case I propose to continue with this set-up unless the fish show signs of distress and/or I have trouble maintaining good water quality. Again, good fish growth and healthy fish are the primary concern....not the plants.

After the water change the water parameters in the tank were:
pH = 7.2
dKH = 2.0
dGH = 3.0
NH3 = 0.0 ppm
NO2 = 0.0 ppm
NO3 = 5.0 ppm

Other than the slight increase in pH which I attribute to the increased volume of the water change the parameters remain the same. After the water change I added 3/8 teaspoon of CaSO4 for 3 ppm of Ca; 3/16 teaspoon of MgSO4 for 1.0 ppm of Mg; and 3/16 teaspoon of K2SO4 for 7.5 ppm of K. I also did my weekly 15 ml of glutaraldehyde / Excel.

It's been almost exactly a month since I first added plants to the tanks and some are showing a strong ability to adapt to the low nutrient environment and some are not. Here are some pictures I took today.

Here is the obligatory full tank shot


The 'Trident' java fern and Cryptocoryne 'Green Gecko' are doing fine


The Persicaria sp. 'Kawagoeanum' (left rear) is not liking the conditions; the Eriocaulon 'Vietnam' are just sitting there


The Myriophyllum sp. 'Guyana' is doing fine with a couple of inches of new growth; I'm unsure if the Bacopa colorata will adapt or not; and the small Eleocharis (hairgrass) plants are starting to put out runners


The Oldenlandia salzmannii is adapting well (left), as are the few sprigs of Ludwigia arcuata however the Limnophila rugosa is not doing much


The Ludwigia sp 'Red' is growing very well but not much color with [email protected]

Hi Michael,

I'm not a 'prove them wrong' type of person so much as wanting to validate or not the assumption that somehow a planted tank is a poor environment for raising juvie discus to full size with good health. The routine water changes the fish require does impact the plants. Since I am using Osmocote Plus tabs for the majority of the nutrients that isn't an issue but I am trying to keep the calcium and magnesium levels up with the soft water changes.

Sand substrate is great for keeping the tank clean. All the mulm just sits on top where you can vacuum it out. It's also great for plants to anchor in. Don't grow carpeting plants where the mulm collects underneath and impossible to clean out.

Hi All,

2020-08-25
Added 4.5 ml of Seachem Flourish Comprehensive

2020-08-26
Based upon recommendations from folks on the forums I have upped my water changes. I will be doing three a week on this 30 gallon tank (24 gallon water volume) with 12 gallons done on Monday, 9 gallons done on Wednesday, and 9 gallons done on Friday. This will be the equivalent of 1.33 complete water changes per week. I did a 9 gallon water change today, did a light vac of the substrate in the front, noticed some green spot algae (GSA) along the front glass just below the substrate line and cleaned that up. Magic Erasers (aka melamine foam) are great glass cleaners (be sure to get the ones with no detergent etc).

After the water change I added 3/4 tsp of CaSO4*2H2O for 6 ppm of Ca (hardness increase approx 0.8 dGH); 3/8 tsp of MgSO4*7H2O for 2.1 ppm of Mg (harness increase 0.5 dGH); 3/8 tsp of K2SO4 for 11.8 ppm of K; and 3/64 tsp of KH2PO4 for 2.0 ppm of P to hopefully reduce the GSA. I also added 4.5 ml of Seachem Flourish Comprehensive.

I did a 9 gallon water change (approx 33%+) today. Also picked up some live adult brine shrimp to give them a little treat. Here they are 1/2 hour after feeding still looking for any BS they may have missed.


Also here is a picture of the big brothers and sisters of the fry I have, notice how the nice coloration is starting to emerge.

love the new shots of the tank!

If i'm reading this correctly, are certain plants that you're trying out struggling because of the lack of nutrients in the water column? Nutrients can't naturally build up in the water column because of the constant water changes and the water params the discus require?

Between restricted nutrients and soft water, which one do you think is affecting your plants more? As for the green spot algae, my knee-jerk reaction is that phosphate levels are low, but is this something you can't dose in a discus tank?

Never really looked into the intricacies of a discus tank so interested to learn more!

Hi @neilshieh, Yes, I suspect insufficient nutrients. I'm not sure if it is the lack of macro nutrients (N,P,K) or secondary nutrients (Ca, Mg). It doesn't appear to be micro-nutrients that are the issue, no signs of an Fe deficiency.

Hi All,

2020-08-31
Today (Monday) I did a 12 gallon water change (50%) and added 3/8 tsp of CaSO4 for 2.98 ppm of Ca (hardness increase approx 0.42 dGH); 3/16 tsp of MgSO4*7H2O for 1.04 ppm of Mg (hardness increase 0.24 dGH); 3/16 tsp of K2SO4 for 5.93 ppm of K. I also added 15 ml of Excel/glut for algae prevention. All fish are active and eating well. They have finished off the three (3) portions of live adult brine shrimp I bought on Saturday with some help from the Turquoise Rainbowfish (Melanotaenia lacustris) that I am conditioning to breed. I try to feed at least one portion of dry food (FD tubifex, Krill flakes, Extreme pellets) and one portion of frozen or live food per day. I have a white worm (Enchytraeus albidus) culture that is not quite ready to harvest yet but I will add them to the food rotation in the future.

2020-09-01
Dosed 4.5 ml of Seachem Flourish Comprehensive for plant micro-nutrients and 3/64 tsp KH2PO4 (2.0 ppm of PO4; 0.66 ppm P; 0.8 ppm K) for GSA

2020-09-03
Today (Thursday) I did a 9 gallon water change (37%), added + 3/4 tsp CaSO4 (6 ppm Ca / 0.8 dGH); 3/8 tsp MgSO4 (2.08 ppm Mg / 0.48 dGH); 3/8 tsp K2SO4 (11.83 ppm K); 3/64 tsp KH2PO4 (2.0 ppm of PO4; 0.66 ppm P; 0.8 ppm K) for GSA. I did a light gravel vac in the front of the tank and siphoned any detritus on the rest of the substrate. It was time to clean the canister filter so I rinsed all the bio-balls and Purigen in tank water as well as one of the two sponges in the filter. The other sponge got thoroughly cleaned in tap water. I replaced the filter floss and started the filter. Here are some pictures I took today.

The full tank shot


Time to rethink some of the plant species. The Persicaria sp. 'Kawagoeanum'. Limnophila rugosa, and the Erio 'Vietnam' don't seem to like the conditions necessary for the discus. I will have to try some different species. On the other had the Myriophyllum sp. 'Guyana', Oldenlandia salzmannii, Ludwigia arcuata, and Ludwigia sp 'Red' seem to be doing well. I have a couple of other species I want to try maybe I can do some changes this weekend.
