Thank you for the good advice all. My freshwater set up is by necessity low tech so I'm not too bothered by that.
I actually came to this forum via google because of your S650 Shaun! Lovely tank!
Well now it's world famous then! Lol. I wonder if I'll get a badge or something....
I would agree with some of the above and keep things as simple as you can and keep on top of water changes. Fancy gadgets can fail, go wrong etc so I've tried to avoid them as much as possible
I would also agree and say that looking after the water parameters in a larger tank is much easier than in smaller tanks as it's much more stable. So assuming you like the hobby I would go as big as you can within reason (not a 500g monster tank!!) otherwise you will then want to upgrade - like what I did. Only problem is the bigger the tank the more fish and corals in needs to fill it and the more expensive!
I personally found the Max S 650 easier to look after than the Max E 260 I had for a few months. It just needs more water and everything else to fill it, but of course it all depends on your space and budget etc. The benefit with these tanks and the variations, is that other than the Reefer series, they are plug and play, so you get everything you need (other than heaters/chillers) to get up and running.
Read as much as you can, look into the Red Sea Reef Care program as that will tell you pretty much what you need to do. Your just a water keeper and if you keep the water in good condition you should be fine. If you don't, and let things go, then bad things or problems start to happen so keep up with at least 10% weekly water changes and make sure you use a good quality salt from the outset.
I can certainly recommend the Red Sea Coral Pro as this will maintain many of the parameters in terms of foundation elements etc with regular water changes, before you need to enter the world of dosing foundation elements to improve water stability. I currently use the standard Red Sea Salt but I'm dosing the various elements separately.
And just a bit of advice from what I have learned which will prevent many of the problems with algea etc you read about. Keep your phosphate nailed down to around 0.03ppm or thereabouts. Use whatever method you need as there are many. I use Rhowaphos in a reactor. Also keep Nitrate at less than 10ppm but don't try and go to 0ppm. If you keep these well under control from the outset, you will enjoy the hobby even more.
Anyway enough of my rambling!
