"Hard" algae...

[MaloK]

These specs says it all

A razor blade is sharpened at 7°-12°, With a thick beard you could stand 20°.

Held at 45° that's going to skip a lot. I mean the blade is 30° and more off cutting edge "best position"...

So I buy the cheap plastics one and melt the tip with a heat gun and make sure they solidify as I want.

Because for all the time I have been keeping aquariums. Not a single of these geniuses ever tried it. And even the stainless ones are exact replica.

And something that is worse is if your tanks are braced. you are going to hold them over 50°

And no one ever complained.

Yeah sure.

My hands and arms are in tanks all the time. I have no issues using my hand and a razor blade. It is actually a better way to removed algae as it is as efficient as one can get in terms of removing the algae in one pass, especially the hard stuff. For softer I have pads, a pad on a stick and then the Kent long handle with all the various blades and then their short hand held handle which the same blades fit.

Yeah but your arm has to slip in a one inch gap.

The best would be an Iphone holder with a modded blade holder head that is used from behind the stage.

Bought one of these a few years back. I have only gone through 2 blades but they are easy to get. I chose this one because it was long, I had 25" deep tanks at the time, and it used normal safety razor blades. I use it occasionally because I get the spot algae from time to time. If you are not careful it will make short work of your seals. There are many other ones available.

I have the exact same, loll. It's very good.

So do I. Where do you source more blades? I ran out and can’t find that type of blade.

Search for "standard safety razor blade" on Amazon.

I just bought a box of blades for my @Uberhoust style scraper. I won the scraper in a raffle, and it's good.

I get algae as tough as nails, so much it takes several passes with a hand held painter's blade. Mine isn't green, but is grey. I also get a red one, two actually, one of which can put up a fight. I'm good at algae.

As a dedicated standard blade user.

If it gets really tough, And you fancy your tanks transparency, look at the Wilkinson sword razor blades They have proven the utmost nick resistance for me.

And the funniest part is a pack of 6 can outrun a cheap 100 pack. At half price... I think you can get 10 for 12$ somewhere. I paid 12 for 6 blades last time and they resist multiple dips... A lot more than the free ones that came with the scraper.

But they have the higher carbon and chrome level that makes them harder and rust resistant.

And the price... But if you replace them every time by default is another story.

Depends on workload rate and load.

It's not coralline algae. It's just green spot algae and a single sided razorblade or even a credit card can normally scrape it off.
