anyone have any experience with the Marina Slim Filter??? I have a 20g long started, it came with an internal Whisper, but that thing is huge(taking up valuable fish space
) and puts out a current that would throw a shark into the wall(not adjustable). Tank is cycling right now with no fish. Petsmart has these Marina Slims 20 on sale for $17.99..just wondering if they are worth it and will be enough for this tank.
Also one more question, also in need of a good reliable heater, any suggestions??
OH and sorry to be a pain, where is the best deal to buy a water test kit, most I've looked at are in the $30 range, is there anything else out there???
