lol of course you can
I bought my tank 6 weeks ago from lfs and he simply told me..."fill up (with declor water) and come bk tomorrow to buy some fish"
Of course i did
However..1 day after placing 10 x neon tetra, 3 x clown loach , 1 x dwarf plec i found this forum
(moving clown loach in a few weeks as ive since learned of their size)
Since then ive spent about 4 hours a day on here trawling through, asking questions and helping others (where possible)
I learned all about the cycling process (fishless and fish in)
Only wish id been informed earlier
Not to worry tho as 2 days later i went to another lfs (smaller but much much better) they gave me a nice piece of used filter media (sponge) which i took home in tank water and placed inside my filter
I purchased all the liquid test kits for PH, Gh, Kh, Amm, NitrIte and nitrAte and have been performing them at least 4 times weekly (for now)
Only once had a small ammonia spike of less than 0.25 mg/l (at which time i carried out a 40% water change (declored and similar temp)
My ph is steady at 7.4 (reducing naturally with a nice big piece of bogwood)
KH is steady at 7 degrees
Amm = 0
NitrIte = 0
NitrAte = never more than 30 mg/l (As I now have a lovely pair of bolivian rams)
(My tap water rested has a ph of 7.5, ammonia = 0, NitrItes = 0 and nitrAtes = around 18 mg/l)
My tank got ich on the second week and i treated it (med and raising temp slowly to 30c) Ich went last week and i medicated 72 hours after to be sure. Reduced temp back down to 27 c and inserted new carbon sponge
(Everything i have done plus loads loads more i have learned in the past 5 weeks thanx to this great forum)
