tbh its not been to expensive to do, i'd say well under £200 for the lot inc tank and filter lol get looking in the bargins
hope everything drops back to normal, i had wierd readings on my tests last night so 'ive off the co2 till i get in tonight, then it will drop right down, now i have the cutoff valve im ok for co2 now, i can off it and on when i need to
thinking i need some more quick growing plants though
