Hello fellow planted tank lovers!
A few days ago my extremely cheap CO2 system in my 75 gallon completely died, and I do not want to refill it again because it is defective. I've been thinking of two options: 1) getting a new CO2 system or 2) getting two new fish instead.
My flora: Anubias, several echinodorus, rotala, staurogyne repens,and java fern. IIRC these are all relatively low demanding plants.
My fauna: 7 discus
Ferts: Flourish as instructed
Lights: (1) Current Satellite LED, (1) Finnex Ray 2 LED Daylight
Filters: Diatom as needed, Eheim Cannister, Emperor Hang on
Tank conditions: 84.5 F, 0-10 ppm Nitrate, 0 nitrite, 0 ammonia, pH 6.5-7, and I do daily 10-15g water changes.
Should I get two new discus and let my tank grow without Co2 for a while and see how it does, or should I lean more towards a new CO2 setup? Oddly enough, my 25 gallon W/O CO2 has the same plants and has much more plant growth with less light and same ferts.
Thank you all for the help!
EDIT: It is important to note that with the addition of two new discus, I would trade out two others currently in my tank. Some time ago when I was less experienced, I ordered some discus and two ended up being stunted. They are very small, do not eat much, and will not grow past the 3" size they are now. 5 of my Discus are very large, healthy, and eat like monsters.
