TEST KITS!!!!Who's the pussy that's needs test kits..!?!?!?!If that's the case, taste the freakin water...WARNING:Tongue may turn green(Algea problem), Yellow(High Ammonia), black(your fish are dead).....For real....(To me)Test kits are like undergravel filter plating, money schemes...Fine, buy one, but after the first month you'll slap yourself in the face and wished you would of rather spent the $20 on something more important like food....To avoid the thought of even needing a test kit, simply stick to a basic routine....Weekly 25-40% water changes and gravel cleaning....Geez, gravel is pretty much for decorations, try "lightly dusting" gravel throughout the tank....Just enough to cover the bottom, less than 1/2inch deep....This makes less space for crap to hide in, making weekly cleaning much easier...Ah yes, the slightly gravel-almost bare tank look....I feel clean everytime I look at mine....BTW, I do (3)25% water changes every week...On Sundays, it's not uncommon for me to sneek in another 25-40% water change....
