High phosphate dilemma - help needed

[BryanM]

My experience has not been that using GFO likely leads to dinos.... that is just my experience though, and I've used a lot of it over the last year.

I've also used Lanthanum in to a filter sock to try and mitigate tang risk, never lost a tang, but I found using LC to be finicky.

I think the easiest way is to just dose silicate while using a binder, but growing macroalgae or an ATS will use little to no silicate.

I’m not dosing silicates anymore but I have a diatom bloom that I need to keep. I had a refugium full of chaeto but it is slowly dying because of the vodka dosing. There won’t be anything left of it soon.

I have no room for any algae turf scrubber.

I’m sure it doesn’t for most tanks but in my case removing the silicate and diatoms will leave room in the ecosystem for Dino’s to come back. They were prevalent in my tank for 5 years so very, very stubborn.

In that case I'm sure I'd opt to dose silicates, or choose another method to lower phos.

I'm a big proponent of algae turf scrubbers.
