I believe you are referring to coral snow from Korallin zucht, nothing like the other brands. I believe it’s major deal is chalk/calcite (side note, supposed to help get rid of vermitid snails), which clarifies water; kinda like carbon.
No GFO, that stuff is no bueno. Dosing PBNS, its working, it was way worse, under control now, also scrubbing out and dosing DIY coral snow. I threw in some dove snails, and now they are laying eggs everywhere....free CUC..
its downstairs, I just wanted a bit of counter space to place food and water testing stuff.... I find it useful. its more of a commercial setup.... I live alone, so no wife to bug me to wanting it to match the furniture.
the coral snow is by KZ and is sold at BRS. The yellow snow is a coral food sold by algae barn.
The coral snow is mostly a calcium carbonate, not really sure if KZ puts anything else in there.. They are really secretive and will not list ingredients, but when its dry, it has a chalky finish on the surface. There is a thread on reef2reef on how to make your own, the product sold on BRS can be expensive over time.
I printed these corner tabs that rest on the glass and purchased a standard window screen frame from home depot, and some clear 1/8 square netting from ebay. If you need a set, I can print them for you at no charge...
just pay for postage which should be a few bucks at the most.
I have the nuts on the top section of the rail already inserted, I just have to print out some hinges, and am going to use 1/4" plywood, and frame it with aluminum to prevent it from bowing. I will probably install magnets at the corners where they meet to prevent it from gapping.
it will be a while till I get to that seeing how busy things are getting with my work.... I barely found time to get my frame up after having ready and sitting there for 1 month.
