That is my goal, after all this PH stuff is sorted out, to have 5-6 discus and a large school of cardinals. Will that be possible?
yes, but start with getting the cardinals sorted they're just a smidge cheaper then the discus
as far as switching everything around, you can put the fish in a bucket and stick either the filter on the bucket or the filter media inside with them. (or buy a cheap 10gal). Have all your stuff ready before taking the fish out, do it as quick as possible.
as far as plants, I really never wanted live plants, because I kill every plant I've ever planted in the garden, but honestly I have thriving sword plants, grasses, and god knows what else and I don't use CO2 injecter or fert. And, I spend less time cleaning my 55 and 75 gal tanks then what I spend cleaning my son's 10gal. (son is only 6 which is why I do the cleaning) Live plants are actually less maintence then fake ones imho (certain ones anyway). Besides, if you're gonna spend $50 on a fish, live, natural plants are going to compliment it so much better!
thanks for advice on plants guys, eventually I'm gonna take a picture of my plants and make you tell me what they are other then "assorted potted plants from petco" LOL
