See what I mean by different opinions? If you want to set your lights all over again later then by all means forget about Par for now. Why not just do it once? That said you do need to have rock in before you do it . Cycling a tank is another mine field. I have an article explaining in detail the fishless cycle if your interested. A bit of work but will do if you are sure you want to do it. Not off the top of my head. I learn from experienced people
Please don't take this the wrong way, as it is not directed at you individually (at all). It is directed at the entire community.
This person is new and struggling to get her head wrapped around all of this but is very excited to be part of the hobby.
There has been an endless supply of opinions, most of them further complicating the situation instead of keeping it basic and getting her system going with what she has.
People are not looking at the actual situation and instead telling her to buy things because what she has already purchased is
garbage , or there is
better or that suggesting things that are wholly unneeded at this stage in her reefing experience.
None of it is bad advice, it is just being given without consideration for the OPs actual dilemma.
The entire premise from this community should be in context to what she needs to do to get what she already purchased up and running.
She is on very limited budget and just needs to get headed in the right direction. She can build on it as she learns over time and need arises.
The last thing on God's green earth that she needs to do is spend money on a PAR meter or a pile of Hanna Checkers or other advanced equipment. She doesn't need N or P or 2-part dosing, Carbon Dosing or amino acids. All of that crap can wait for many months. If she sticks with the hobby then many of those things will become self evident and part of the natural progression of learning.
She has the basic test kits that she needs and a light that will be suitable at its default settings to grow coral. She doesn't need to tweak PAR or anything else.
So, please, everyone -- let's just focus on helping her with what she has. Step by step.
