Question: I'm using Minecraft Education Edition. I want to summon 3 to 5 fish whenever a player comes closer to a location in the sea and I want it to put some delay for summoning too, for example: 3 seconds.

Can I achieve this with command blocks or with other methods?

Answer: 
**Try resolving the problem using a 'Cure All' batch file.**  

These files list all known active effects from the base game and DLC (and the Wet & Cold and Skyrim Immersive Creatures mods), preceded by the `player.sme` command (which stands for 'Stop Magic Effect' on 'player'), and can be executed using the in-game console.

You can find an archive file with these batch files under *Solution 4* on [this page](https://forums.nexusmods.com/index.php?/topic/872861-tutorial-removing-unwanted-magic-effects-from-the-player/). [Here](http://forums.nexusmods.com/index.php?app=core&module=attach&section=attach&attach_id=40779) is a direct link (you need a (free) account in order to download). The file was created by NexusForums user *LubitelSofta*.  

Be sure to take off all your (enchanted) gear beforehand.

Instructions as per the Nexus forum thread:

> 
> * Extract the files to your Skyrim root folder (not the data subfolder).
> * Edit the Dawnguard, Dragonborn, or WC or SIC batch files (if necessary) so that every shader or effect ID matches your load order (see above).
> * Start the game.
> * In the console type `bat <filename>` (without quotes), e.g. `bat DBMGEF`.

You can remove all applied spells by using player.DispelAllSpells, I believe. Note that this will also remove blessings and apparel effects, so you will need to unequip and re-equip armor to re-apply the effects from armor.
