Upgrade advice

[Scm186]

Good evening, I have a aquatop recife eco 40. I have fish and 4 corals in the tank. The only upgrade I have done is the AI prime 16HD light, and a reverse osmosis system. Looking for suggestions on a new protein skimmer, what you recommended for a dosing system, and a good ATO? Thank you in advance for your time and suggestions.

I would have to say that the tunze 9004 is the best you could get if you wanted to upgrade the protein skimmer ( also R2R has a giveaway for one going on rn! ) just make sure it fits in the back chamber.

not an expert on dosing systems so I will leave suggestions up to other people.

and the top end ato is the tunze osmilator 3155, however the Nano version is highly looked upon, along with jbj’s ato ( not the new nano one but the older normal one ) and a few others.
