# Trouble Shooting

## Basic SK Sump Troubleshooting

1. ***The water level in the crash box is flowing over the top of the Crash Box Weir Baffle:***
   * Make sure that your flow is not more than the recommended flow rate of the Clarisea SK5000 ( *Each SK5000 is rated for 1300 GPH MAX, 2 SK5000s would be 2600 GPH MAX)*
   * Did you install the proper float switch brackets? Please see the Float Switch Bracket Installation instructions for your Gen SK5000 Listed here: [Gen1& Gen2](/installation-manuals/sk-sump-installation/float-switch-bracket-installation-gen1-and-2-only.md) or [Gen3](/installation-manuals/sk-sump-installation/float-switch-bracket-installation-sk5000-gen3-only.md)
   * If you have the proper flow rates listed rates and proper float switch bracket installed, you may need to modify the Clarisea's input pipe as the inlet vents can restrict the flow into the clarisea. The slots in the input tube may be too small and need to be opened up to allow more flow into the clarisea. Make sure that the slots are facing upwards when installed in the Clarisea or you can get air trapped in the pipe and reduce flow rates. These slots over time can also build up with bio slime or algae and cause the SK5000 not to function properly or totally reduce flow. This needs to be done at your own risk as we are not responsible for any parts on your clariseas. Please see the photo below:

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.synergyreef.com/installation-manuals/sk-sump-installation/trouble-shooting.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
