I personally have never worried too much about pH and hardness because I prefer to leave it alone instead of messing with it. I still don't know about housing a male and female... But if your Thai fish has long fins, its probably best to keep him away from the filter.
i have 7.6 straight tap water. its high in sediments, it caked up the humidifier heating coils within 2 weeks of near constant runnng. my cts get 1.6l of 0ppm water to soften it a bit and 600ml ial water (had issues b4 with wandering ph levels bc i didnt control the amount of ial water). the anacharis from 1yr back just bogged down and melted in low ph water and diminished light. funny enough the "root food" plant has been the only plant that didnt die on me. i have a green thumb for terestrial pants but a brown one for aquatic ones o.O.
the vt also has long fins and constantly gets torn up every few weeks (or months) but its a bit better lately. i rarely use aq salt for him for fear it'll damage the organs, he'll blow his tail easily. it even happened without a filter in the tank. he blows it and "trims" it down. when its growing back, he resets the damage
i searched more on the M-F divided threads here and OFL and other senior members said either inaccesiblity and/or obscurity will turn out just fine gievn the 2 temperments. it does give me hope as both DeT and VT are mellow, more like the VT goes crazy for a few days then ignores. Osiris (past 5g occupant)and Halloween (current 5g occupant) dont care if theres another betta on the other side.
