Water changes are a poor excuse for nutrient export I'm sorry if I hurt your feelings saying this but it's true and again I can prove it if you like .....just so we can make sure what's fact and what's not
That's the problem with forums you just get plain wrong info that claim to be facts lol |
Of course coraline consumes dkh.
What I'm saying is that you need a fair amount of coraline to affect your dkh...you also need alot of other calcium eating corals for it to even matter to the rest of the tank.
It takes time for coraline to grow..especially in a tank that isn't being dosed at all.
So worrying about it in a brand new tank is just overkill.
if you buy LR that is absolutely covered in coraline, you may need to worry about it...maybe.
Please do forward me any information you have that proves that water changes offer poor nutrient export.
I have ran skimmerless tanks for years using only WC as nutrient export.
Heres a blurb from wet web media for ya...
Water Changes
Another one of the most basic aspects of aquarium husbandry (and one of the best means of achieving nutrient control and export!) is the performance of regular, modest water changes in your system. In my opinion, smaller, more frequent water changes are preferred over larger, less frequent ones, and are much less labor-intensive. Try changing as little as 5% of tank volume on a twice-weekly basis, and you’ll be astounded at the difference this will make in your system! Fish will be livelier and more colorful, corals will open up like you’ve never seen them do before, and levels of dissolved organic substances, such as nitrate and phosphate, will decrease significantly. Frequent water changes allow the aquarist to help dilute and reduce the concentration of waste products from the system before they begin to accumulate as nutrients. This, in turn, will result in less potential for nuisance algae growth, and a more stable system.
Remember to use high-quality source water when mixing up your saltwater for water changes. Be consistent, methodical, and siphon out as much detritus as you can from the rockwork and other areas from the aquarium. Frequent water changes also give the hobbyist the added advantage of being “in touch” with the system on a very regular basis, resulting in a better understanding of just what’s going on within his or her aquarium. As the old hobby saying goes, “nothing good happens quickly in a marine system,” so the benefits of frequent water changes will begin to manifest themselves gradually-but they will become obvious after a brief period of time. Give more frequent water changes a try!

I do totally agree on your opinion on online forum information, however.
