better than instant ocean a had before(got it with samp).
That's not actually saying much. The IO skimmer is virtually a SeaClone clone.
*Who copied who is irrelevent - they both sucked* An airstone skimmer was more effective and reliable than those two.
I did modify it little, put bigger pump and more air tubes, it skimms now like crazy. Good skimmer for beginners like me
That's the thing. If you buy this skimmer for $40.00, then you want to upgrade the pump and get additional tubes that would cost an additional $20.00 then you are already out at least $60.00 for a sub-par skimmer.
Why not just save up and buy a quality skimmer to begin with?
It is not like you absolutely need to get a skimmer ASAP. You can do well with just regular water changes while you save up for a good skimmer.
This "Beginner" concept for equipment is a dangerous (and expensive) mindset.
"Buy this cheaper equipment now until you decide that you want a better one."
What do you do with the old equipment that no one would buy used? That is money down the dumpster.
One would be better of investing in quality equipment that will provide good performance. If you still want to upgrade to premium equipment later on, there will be a decent market for your used equipment because it is a good product.
Granted that the best equipment for this hobby is beyond practical reach for most of us *cough*Vortech*cough*Radion*cough*, that is no reason to dive into the cheapest, sub-par equipment that we would most likely toss due to poor performance.
Even if you cannot afford the best equipment, there is a large selection of mid-range equipment that will provide the performance that you need.
If you already have the $40.00 today, it would not be unrealistic to save up some more and have around $150.00 for a good purchase.
But that is just my opinion.
