so...the first time i got my co2 tank filled the psi read 1000, lasted me 4 months. the second time i filled it,it lasted a month and half at 800. this time it reads 700. am i getting screwed or what. i checked for leaks on the entire system and there are no leaks. i keep my ph at 6.6 it kicks on one hour before the lights and off one hour after, of course it kicks in when needed during the day

hello all, I am pretty new here and have been reading a lot of post on bba. I have a 125 gallon tank with eco complete, i have two quad t5ho lights(312watts total). the plants i have are myrios, a couple of swords, three ulvaceus, 4 tiger lotus plants. According to the watts per gallon rule i have 2.5. i also have co2 injection. i do a 50% water change weekly and i also use dry ferts from greenleaf. I was adding ferts daily according to the die schedule but i was getting way to much algae.…
