We admit it ? there are moments when you'd like to give up on this hobby. For example when algae have become a pest, overgrowing all the plants and the entire hardscape like driftwood or rocks.
Or when you maybe have some pests of animal origin in your tank that threaten to eradicate your beloved shrimp or fish offspring as they reproduce massively.
In such a case you'll need to get some First Aid that keeps you from giving up this beautiful hobby.
