Coral Snow question

[WaterWorld]

I have been battling dynos and cyano with water changes and manual siphoning it out. I have a 32g Biocube not currently running a skimmer but i do have the cheap biocube skimmer in storage. I dont usually use additives but I’m considering using coral snow and some bacteria to see if it will help with the cyano/dynos. My question is should I use Snow if i dont have a skimmer, or even if I add the cheapo biocube skimmer back. Everything I read suggest a good skimmer when dosing

A skimmer is always a good idea when using a lot of these types of products as it increases aeration.
