Aquatop SP7-UV Submersible UV Filter

Good move. For me it's more the secondary impact it can have.

Whats caught in the filter is 99% dead. But in large quantity it has great chances to provoke a chemistry swing.

So clearing them off is the best way not to have a low oxygen / high ammonia output impact from the massive bacteria generation that it will occur if left to decompose in the filter.

Absolutely. I was already concerned about a possible ammonia spike with the mass die off of algae. I've been doing 50% water changes every 2-3 days during the green water bloom and that will continue for a bit to help mitigate any ammonia build up.
That said the tank is now 5 months old, it's got 2 Penguin 200's both with additional sponges on them so it's probably a bit over filtered. Not to mention the nice deep substrate.
