Hello. I have 200lt tank (Juwel Lido 200) with 50lt sump and there is 2 gymnothorax tile, 2 green spotted puffers and the main reason of making a scrubber - 30cm porcupine puffer grown from 5cm for about half of the year, waiting for me to buy a larger tank for him. Since I can`t do it right now, I decided to make a scrubber first. Also I`m currently using all-in-one biopellets, carbon reactor and skimmer (Juwel Seaskim). Nitrates always remain the same 20ppm and phosphates is unknown, but I have a huge growth of algae all over the tank.
It`s size is 20x50cm or 1000cm2 and it feeded by both Tunze 1074/2 overflow and directly from Aquael 2000 pump. The slot is 5mm and seems that is possible to make it wider. The light is 50w chinese led grow flood light each side about 15cm from scrubber. 18/6 per day. I like it because they`re splash-proof. Feeding is 1 frozen shrimp or mussel per day and it`s about 15grams. I`m not sure about cube equivalent since all of them are predators and eat the same.
The problem is that I have green growth on my scrubber but it is not thick as on many forum users pictures, and it mostly the green slime. What`s wrong with my setup?
