Warped has pretty much rounded out the discussion. lol IMO, yes, it is adequate filtration. Don't be fooled though, not all manufacturers will sell you the correct equipment in a pre-packed setup. Most of the time you still need to upgrade the components. I aim for 10x filtration for a hob filter and roughly 3 to 5x filtration for a canister. I'd say you are adequate.
Do not waste your time or money on the test strips. They collect moisture and end up giving incorrect results. It is cheaper to just buy the API FW Master Test Kit. I did the math a few years ago and the strips rounded out to be about $1.50 a test. The API Master Test kit was roughly 7 cents per test. The API is a larger investment up front (maybe $15 to $20 for the entire kit) but it will last you a long time. You'll end up tossing the solution bottles due to expiration before you use them up. The test you will use most often in the beginning is Ammonia and Nitrite. Those tests are done in a matter of seconds. Use a baby medicine syringe (un-used of course) and measure out 5 ml of water from the tank. Squirt in the vile, add the drops, shake, and let it sit for a few minutes. Easy Peasy.
