I have this sand in every tank I own. Great stuff and the larger particle size keeps it on the bottom even with bottom dwellers. Cheap and really clean tooanother choice is quick-crete all purpose sand,do a search,i forgot who posted a thread with a video.but i tried it,look good,bigger grains.you can get it in HD or lowes 50lb for less than 5 bucks
The problem with diatom algae is it feeds off silicates how often do you scrape the algae out? I spent about a month scraping it out of my tank and removing it before it stopped growing. Check your filters to, mine did not stop growing until I cleaned the algae out of the filters to.
i read your not suppose to scrap it off the glass or anything, and when i did i found it got worse... so i left it for just before doing a large WC 80% or left it for the cihinese algea eater i added couple weeks ago..and yea as far as i know all PFS is silica sand which feeds brown algea, and i dont have any brown or green algea in my filters, never noticed any at all andi only clean the filters out when needed once flow is reduced.. all though i have noticed after taking the t5h0 fixture off my tank and just having a t8 fixture on there i dont get ANY algea any all... so maybe between the t5h0 lights and silica in the sand and my crappy tap water (20ppm nitrate/1ppm phosphates) it was unbeatable with a bright nice light....but i can leave the t8 bulb on for 12 hrs a day with no effect in my tank at all
I use a brush so it actually sticks yo the brush. If you scrape be sure to vacuum after. Bristlenose plecos will eat it all up.
