If I had no other option but to have a hang on skimmer, what skimmer is the best you can get or you guys to recommend. Tank: AR620-T 130 litres. Now I have been told by my local petshop that I don't necessarily need a protein skimmer and a sump with all its medias. But here I am being told differently. And now I am confused. The tank I have is not necessarily suitable for a marine setup yet on the Aqua 1 site it says it is, otherwise I would never of persued this marine setup.
It is hard to explain, but because of the restrictions on access to the tank for any water for sump and protein skimmer, this makes things very difficult. Ive been told I can't drill through the glass because it is toughened and may crack and explode, but then other people are telling me different.
Scenario's:
1 - If I decide to go with the sump/skimmer, what are the benefits of having a sump with all the medias besides taking all the crapola out of the tank. I.E Will the fish die without a sump/protien skimmer eventually or what?
2 - If I don't decide to go with a sump/skimmer. What things will I have to do to keep the fish alive? Will I I.E have to change the water (10% with NSW) every week? If that is all then I will decide to go without sump due to the implications and extra $300 involved.
