Mr. Saltwater Tank TV Friday AM Quick Tip #111: Once It’s Spent, Your Saltwater Tank Can Use It

Algae on your saltwater tank’s glass is just part of tank ownership. Scraping it off with a magnetic algae scraper works well for simple surface algae and here’s a quick and easy way to get the stubborn bits of algae off your glass with something you likely already have in your house

    Easiest way to clean off Coraline Algae. I’ve been using this for years. Great tip!

  • Ann Marie says:

    Thank you. Off subject but why does live rock turn white?

  • Michael says:

    I have been told that steel wool is another great algae remover. I haven’t tested it out yet to confirm though.

  • Reggie says:

    Thank me later. 🙂

    Lil’Chizler – $4 for a pack of 5

    Steel wool will scratch the hell out of yout tank and small steel pieces will fall into your system. Made that mistake years ago.

  • dave from brooklyn says:

    Hey Mark, did you move already? Is that the new place?? Hooray, no more drafts 🙂

    Working your diving certification into a random conversation… exactly what I like to do. 🙂

    What is your favorite dive site?

    I’ve been doing this for years to scrape panels on my acrylic frag tank. I save expired credit cards, gift cards, old hotel card keys, etc. for this purpose. For the really, really hard stuff (e.g. thick coralline from ignoring your tank), the Lil’ Chizler that Reggie referred works great.

  • Karen T. says:

    Also works handy when you live in a southern clime, so you don’t own an ice scraper, but need to scrape that infrequent morning frost off the windshield!

  • Jimbo says:

    Come on dude are you really going to use Steel wool common sense dude! wow (peace).

  • Jerry says:

    Definitely no, on the steel wool. I don’t know if that was a joke or attempt to mislead some poor, unsuspecting new hobbyist but I hope not. Steel wool could lead to a plethora of problems in addition to scratching the glass and shredding silicon seals. Common sense, yes, but there’s always that one person out there that will try it, and mess his tank up in the process

    I think you should delete that post, Mark; before someone sees it and thinks it a good idea!

  • mike says:

    I’d be wary of using those cards that have a chip embedded in them – the contacts may have copper in them and thats not an element you want in your reef tank. Also be aware that some of those plastic pan scourers I have seen used for this job can have abrasives embedded – which will leave micro scratches on glass and acrylic.

    Hey Mark I know you have a lot of things to do and I remember you saying that some times you dont even get to look at your tank. I am sure you get this question a lot and I am sorry if you dont want to hear it but I was wondering when you will be doing another up date on your tanks. The only reason why I am asking is because I am really interested in how your tanks are doing hopefully you can respond and make another update. Thanks for all your time

    hello i have a 180 gallon fish only saltwater. only 5 small 2 inch fish.i did a 60 gallon water change 5 days; and now i tested my water and the nitrate and nitrite are still s bit high today i changed my filter sponges from the sump will this help? i do plan on buying the seachem Prime products as well as the De nitrae and Matrix media products please help!!!

  • Jerry says:

    Sounds like your tank is cycling for some reason. 60g isn’t enough to cause that to happen on a 180. You should probably refrain from changing anymore sponges, as that could accelerate the problem. Clean them, if needed, but don’t replace or remove any. Being a fowlr, I don’t think you’ll have an issue with a small cycle but you should find what triggered it, so it doesn’t happen again

    Apologies to Mark if I stepped on toes there. Not sure how actively old threads are monitored!

  • Larry…what test kit did you use? A water change shouldn’t cause a nitrate/nitrite jump
