Test 1: On the soft algae, it took many, many more passes with the scrubber side of the Fl!pper than with the other two scrapers. In the video below, I go into great detail explaining to you how to finish a concrete floor smooth using just a mag float and steel trowel. It’s possible to scratch your tank if you use an algae scraper improperly, especially if you have an acrylic tank. Make sure to follow all the manufacturer’s instructions. Be especially careful while cleaning along the substrate. Getting even a single grain of sand trapped between the scrubbing pad and the glass can cause major scratching. How to Choose an Algae Scraper

If no errors occur, the floating point value with the magnitude of mag and the sign of sgn is returned. We can only offer to replace damaged glass items if we are notified within 48 hours of you receiving the delivery. We cannot replace glass bulbs/tubes unless they become faulty within the initial 14 day period.

The corner-shaped attachment didn’t do me much good at all. The swivel it’s on is too loose so you can’t actually scrub with it except at really awkward angles. But, the scraper blade is really great for cleaning along the surface of the substrate. You have to be careful and slow as you clean along the substrate line anyway, so it’s no big deal to slow down and take the time to use the scraper blade on the Fl!pper in this area. I was really disappointed. This was one of the main things that I noticed about this kit but it really didn’t work well at all. So, after trying out the magnetized scrapers on the soft brown algae, we then tried them on the green spot algae to see how they did on the really tough stuff. Long-Handled Scrapers These three videos and my explanation should help you understand how to finish concrete smooth using a hand trowel.

You'll have to wait for almost all that mixing water to evaporate before the concrete will be firm enough to mag float. Keep aquarium lights off for at least four hours after the new arrival is introduced into the aquarium.The long-handled scrapers are a toss up for me. I like some of the different attachments on the Hygger kit, but I also found that the Fzone scraper was simple yet extremely effective. I would still recommend using the Fl!pper and the Mag-Float in combination so you have the best of both worlds. The mag float helps smooth out concrete when it is softer, it brings a finer cream or paste to the surface and prepares the surface for hand troweling.

Keep in mind, timing is everything when finishing concrete. Starting too soon or too late greatly impacts the final results. The scraper blade side was much better at removing the green spot. I did have to go really slow, but the blade was able to get it up. I actually found that I greatly preferred the plastic scraping blade over the metal one on the green spot algae.

Drip Method

TLDR: This scraper has a really cool handle and large scrubbing pad, but it’s not as strong as the Mag-Float. The Aquawing did OK on the softer brown algae, but it struggled a bit on the green spot algae. If no such floating-point type with the greatest rank and subrank exists, then overload resolution does not result in a usable candidate from the overloads provided.
