Hello everyone I am in the process of cycling a 20 gallon high and the only place it fits is right by the window. I put up a backing but as you can see in the pic it is still getting way too much light on the left. I read that filters with a skimmer and UV
sterilization help with algae growth. Is this true and should I invest in one due to my lighting issue? No readings yet as far as water parameters are concerned. It has only been 3 days. I used tetra safe start plus and added some good BB from my other tank. I modified the HOB
whisper 20 so that the bio bags filled with carbon were switched to bio rings since they support a large surface area and hold BB. I just dumped the carbon out of the bag and filled It with small Fluval rings.
