bshumake,
You do have skills in writing and expressing your thoughts. It's a pleasure reading your post.
Thank you for the nice comments.
The only way I can equate a successful reef system, is that it is like a symphony playing a wonderful suite. All the individual instruments chime in at the appropriate moments to complete the symphony and make it into a master piece. It can take a lot of work, trial and error and studying the known facts to make your reef system (master piece) come together. Once it does, it is a wonderful thing to look at and enjoy.
In a reef system you are working to bring your water parameters, lighting, feeding & tank occupants selected to a harmony where all your occupants are happy and flourish, yet exclude the weeds & pests you do not want. Easier said then done. :lol:
The subject of weeds in a reef system is similar to weeds in a garden. Most successful gardeners start with good soil and carefully prepare the soil to eliminate pests and weeds. This can be done in many ways.
In a reef system, this can be accomplished by carefully quarantining all your items to be placed in your reef system. This includes everything. Introducing live rock, live sand & possibly natural seawater without proper quarantining is asking for problems.
As in gardening there are many weeds that are easily controlled, buy pulling them by hand. However, there are always weeds that lead to major problems. Trying to control these type of weeds can be difficult if they are introduced into your system. Usually there is no one easy method for removing them. Instead, you may be faced with using many procedures to gain control and sometimes chemicals may help.
Carefully observing your reef system on a regular basis will allow one to detect these weeds when they first start growing. Acting as quickly as possible when you first notice them is of great importance. It is much easier to control these type of pests when they first start then to wait until they have taken over your reef system.
If the weeds are allowed to get out of hand, then you are faced with other problems such as the increased organic matter these weeds create in your water column. When you remove them, parts of them end up in the water column. Most of these weeds in the reef system will create other toxic substances (built in defenses) into your water column. All of this increased DOM takes a while to remove from your water column. Many of these toxins have adverse effects on your coral and possibly fish, which is not taken into consideration as you kill them off. It is possible that this is an underling effect that causes problems with many coral and possibly fish that hobbyists attribute to other things.
To sum everything up, I feel that particular attention to the increased DOM from weed infestations is one of the critical aspects commonly overlooked in any weed pest control program used in a reef system. Your use of the Zeoliths to help accomplish this is certainly one approach to removing DOM along with other known methods such as proper skimming, running GAC, proper water changes & running other filter methods that grab the DOM from the water column (using fine filter bags, sand filters & diatomaceous earth filters may be included here).
