You could use Poret foam in the corner to cover you heater and water pickup.  https://fish2water.com/corner-filter-hmfs.php

I've used these filters in my tanks for 6 years now and never had to clean them and they do help to create a cleaner looking tank.

It also means that for tanks which have canister filter I remove all the foam and add matrix to the filter trays.

Its also rather concerning when you read something like this:
Mycobacteriosis Fish Tuberculosis

I did not know that high KH would help, I have been keeping my Cichlid at above 10 GH but keeping the KH high has been ready hard.

I'm also new to cichlids (about six months) I've found this forum great. Good people and even better information.
